      Description/Classification

      Description

      Sacubitril; valsartan is a combination product containing sacubitril, a neprilysin inhibitor, and valsartan, an angiotensin II receptor blocker. Sacubitril; valsartan is indicated in adults to reduce the risk of cardiovascular death and hospitalization for heart failure in patients with chronic heart failure. The benefits of sacubitril; valsartan therapy in adult patients with chronic heart failure are most evident in those patients with left ventricular ejection fraction (LVEF) below normal. In the PARADIGM-HF trial, sacubitril; valsartan was superior to enalapril in reducing the rate of cardiovascular death and hospitalizations related to heart failure in adults with symptomatic chronic heart failure (NYHA class II to IV) and systolic dysfunction (LVEF of 40% or less). Most patients were also receiving standard heart failure treatments including beta-blockers, diuretics, and mineralocorticoid antagonists.[59939] In the PARAGON-HF trials, the rate of the primary composite outcome (first and recurrent heart failure hospitalizations and cardiovascular death) was lower in the sacubitril; valsartan group at 12.8 events per 100 patient years compared to the valsartan group at 14.6 events per 100 patient years (RR = 0.87 (0.75, 1.01), p = 0.06). The PARAGON-HF trial enrolled adult patients with symptomatic heart failure with LVEF of 45% or higher and structural heart disease (either left atrial enlargement or left ventricular hypertrophy). Most patients were also receiving a beta-blockers and diuretics.[66422] In an analysis of both the PARADIGM-HF and PARAGON-HF studies, greater risk reductions were observed with patients with LVEF below normal treated with sacubitril; valsartan.[59904] In pediatric patients 1 year and older, sacubitril; valsartan is indicated for the treatment of symptomatic heart failure with systemic left ventricular systolic dysfunction. Results from PANORAMA-HF trial showed a reduction from baseline in NT-proBNP of 44% in sacubitril; valsartan-treated patients compared to 33% in enalapril-treated patients. While not statistically significant, the reductions were similar or larger than what were seen in adult patients. This effect on NT-proBNP was considered a reasonable basis to infer improved cardiovascular outcomes in the pediatric populations, as similar outcomes were seen in the PARADIGM-HF study. Sacubitril; valsartan is contraindicated with concomitant use of an ACE inhibitor; allow a 36-hour washout period between administration of the 2 drugs. The most common adverse effects reported include hypotension, hyperkalemia, cough, dizziness, and renal failure.[59904]

        Angioedema has been reported with the use of sacubitril; valsartan. During clinical trials, angioedema was reported in 0.5% of patients treated with sacubitril; valsartan compared to 0.2% of those treated with enalapril. The incidence of angioedema was higher in Black patients (2.4%) receiving sacubitril; valsartan compared to non-Black patients (0.4%).[69374] If angioedema occurs, immediately discontinue sacubitril; valsartan therapy, provide appropriate therapy, and monitor for airway compromise. Do not readminister sacubitril; valsartan to patients who have experienced angioedema with its use. In cases where swelling was confined to the face and lips, the condition generally resolved without treatment; however, antihistamines have been used for symptom relief. Laryngeal edema may be fatal. If there is involvement of the tongue, glottis, or larynx, administer appropriate therapy (e.g., epinephrine) to ensure airway patency. Anaphylactoid reactions, pruritus, and rash have been reported during postmarketing use of sacubitril; valsartan.[59904]

        Drugs which affect the renin-angiotensin system have been associated with fetal and neonatal abnormalities when administered to pregnant patients. Adverse fetal and neonatal effects have included hypotension, neonatal skull hypoplasia, anuria, reversible or irreversible renal failure, oligohydramnios, and death. Oligohydramnios has been associated with fetal limb contractures, craniofacial deformation, and hypoplastic lung development. Due to the potential for teratogenesis, every effort should be made to discontinue sacubitril; valsartan and consider alternative therapy during pregnancy.[59904]

        Hypotension has been reported with the use of sacubitril; valsartan. During controlled clinical trials, hypotension was reported in 18% of patients treated with sacubitril; valsartan and in 12% of those receiving enalapril. Hypotension was reported as serious in 1.5% of patients in both treatment arms. Orthostatic hypotension was reported in 2.1% of patients receiving sacubitril; valsartan and 1.1% of patients in the enalapril group. Falls were reported in 1.9% of those receiving sacubitril; valsartan compared to 1.3% of those receiving enalapril. Dizziness was reported in 6% of patients in the sacubitril; valsartan group and 5% in the enalapril group. Volume and salt depletion should be corrected prior to initiating therapy. If hypotension is anticipated, initiating therapy at a lower dose may be necessary. If hypotension occurs during therapy, ensure hypovolemia has not occurred and consider dose adjustments of diuretics and other concomitant antihypertensive drugs. If hypotension persists despite such measures, reduce the dosage or temporarily discontinue sacubitril; valsartan; permanent discontinuation of therapy is usually not required.[59904]

        Decrease in renal function has been reported with the use of sacubitril; valsartan. During the PARADIGM-HF clinical trial, renal failure (unspecified) was reported in 5% of patients in both the sacubitril; valsartan and enalapril groups. Increases in serum creatinine of more than 50% were observed in 1.4% of patients in the enalapril run-in period and 2.2% of patients in the sacubitril; valsartan run-in period. During the double-blind period, increases in serum creatinine of more than 50% were reported in approximately 16% of both treatment groups. In the PARAGON-HF trial, increases in serum creatinine of more than 50% were reported in approximately 17% of sacubitril; valsartan patients and 21% of valsartan patients. Oliguria, progressive azotemia, and, rarely, acute renal failure and death have been associated in patients receiving angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs) whose renal function depends upon the activity of the renin-angiotensin-aldosterone system (e.g., patients with severe congestive heart failure). If a clinically significant decrease in renal function develops, closely monitor serum creatinine and decrease the dose or interrupt sacubitril; valsartan therapy. In addition, serum creatinine and blood urea concentrations may increase in patients with bilateral or unilateral renal artery stenosis.[59904]

        Hyperkalemia was reported in 12% of patients treated with sacubitril; valsartan and 14% of patients treated with enalapril during controlled trials. Potassium concentrations more than 5.5 mEq/L were reported in approximately 4% of patients in both the enalapril and sacubitril; valsartan run-in periods. During the double-blind period in the PARADIGM-HF trial, approximately 16% of both treatment groups reported potassium concentrations more than 5.5 mEq/L. During the double-blind period in the PARAGON-HF trial, approximately 18% of sacubitril; valsartan patients and 20% of valsartan patients reported potassium concentrations more than 5.5 mEq/L. Monitor serum potassium periodically and treat appropriately. Dosage reduction or interruption of therapy may be required.[59904]

        During controlled clinical trials, cough was reported in 9% of patients receiving sacubitril; valsartan compared to 13% of those in the enalapril group.[59904]

        Rhabdomyolysis has been reported with the postmarketing use of sacubitril; valsartan. During clinical trials, evidence of possible muscle harm was noted.[63529]

        Contraindications/Precautions

        Absolute contraindications are italicized.

        • ACE-inhibitor induced angioedema
        • angioedema
        • Black patients
        • breast-feeding
        • diabetes mellitus
        • hepatic disease
        • hereditary angioedema
        • hyperkalemia
        • hypotension
        • hypovolemia
        • pregnancy
        • renal artery stenosis
        • renal failure
        • renal impairment

        Sacubitril; valsartan is contraindicated in patients with a history of ACE-inhibitor induced angioedema and in those with angiotensin II receptor blocker (ARB) therapy induced angioedema. Sacubitril; valsartan should not be used in patients with hereditary angioedema. Angioedema was reported during clinical trials of sacubitril; valsartan. Black patients and patients with a prior history of angioedema may be at increased risk of angioedema with sacubitril; valsartan.[59904]

        Use sacubitril; valsartan with caution in patients with hypovolemia and in patients who exhibit signs of hypotension. Sacubitril; valsartan lowers blood pressure and may cause symptomatic hypotension. Patients with an activated renin-angiotensin system including patients who are volume or salt depleted (e.g., those treated with diuretics) are at an increased risk of developing hypotension. Correct volume or salt depletion prior to initiating of therapy or start sacubitril; valsartan at a lower dose.[59904]

        Sacubitril; valsartan may decrease renal function in patients whose renal function depends upon the activity of the renin-angiotensin-aldosterone system (e.g., patients with severe congestive heart failure). Treatment with angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) has been associated with oliguria, progressive azotemia and, rarely, acute renal failure and death. Closely monitor serum creatinine, and reduce the dose or interrupt sacubitril; valsartan in patients who develop a clinically significant decrease in renal function. Similar to other drugs that affect the renin-angiotensin-aldosterone system, sacubitril; valsartan may increase blood urea and serum creatinine concentrations in patients with bilateral or unilateral renal artery stenosis. Monitor renal function in patients with renal artery stenosis.[59904]

        Sacubitril; valsartan therapy may result in hyperkalemia and should be used cautiously in patients with risk factors for hyperkalemia, such as severe renal impairment, diabetes mellitus, hypoaldosteronism, or a high potassium diet. Monitor serum potassium periodically and treat appropriately, especially in patients with risk factors for hyperkalemia. Dosage reduction or interruption of sacubitril; valsartan therapy may be required.[59904]

        Administration of sacubitril; valsartan is not recommended in patients with severe hepatic disease (Child-Pugh class C), as no studies have been conducted in these patients. Dose adjustments are recommended in patients with moderate hepatic impairment (Child-Pugh class B); no dose adjustment is required when administering sacubitril; valsartan to patients with mild hepatic impairment (Child-Pugh class A).[59904]

        When pregnancy is detected, discontinue sacubitril; valsartan as soon as possible and consider alternative therapy. If sacubitril; valsartan must be used during pregnancy, advise pregnant patients of the potential risk of fetal harm. When used during the second and third trimesters of pregnancy, drugs that affect the renin-angiotensin system (e.g., ACE inhibitors, angiotensin II receptor antagonists) can cause reduced fetal renal function and increased fetal and neonatal morbidity and death. Use of drugs that affect the renin-angiotensin system during pregnancy can cause fetal death or injury such as hypotension, neonatal skull hypoplasia, reversible or irreversible renal failure and death. Anhydramnios and oligohydramnios have also been reported. Development of oligohydramnios may be associated with decreased fetal renal function leading to anuria and renal failure and results in fetal limb contractures, craniofacial deformation, hypotension, hypoplastic lung development, and death.[59904] An observational cohort study evaluating the outcomes of angiotensin receptor blockers (ARBs) use during the first trimester of pregnancy found an increased rate of major birth defects compared to non-hypertensive pregnancies, 5.4% and 3%, respectively; the difference did not reach statistical significance. The authors noted that there was a higher risk of major birth defects with ARB therapy beyond 6 weeks of gestation compared to discontinuation of ARBs before week 6, 7.3% and 2.8%, respectively. The rates of prematurity and reduced birth weight were also increased in the ARB group. There were no statistically significant differences in the rates of major birth defects, spontaneous abortions, or preterm births between women with chronic hypertension treated with an ARB versus methyldopa.[64367] Once pregnancy is detected, perform ultrasound examination if sacubitril; valsartan exposure occurs beyond the first trimester. In rare cases, when another antihypertensive agent cannot be used to treat a pregnant patient, perform serial ultrasound examinations to assess the intraamniotic environment. If oligohydramnios occurs, discontinue sacubitril; valsartan unless it is life-saving to the mother. It should be noted that oligohydramnios may not appear until after the fetus has sustained an irreversible injury. Closely observe newborns with histories of in utero exposure to sacubitril; valsartan for hypotension, oliguria, and hyperkalemia. If oliguria occurs, blood pressure and renal perfusion support may be required, as well as exchange transfusion or dialysis to reverse hypotension and/or support decreased renal function. The effect of sacubitril; valsartan on labor and delivery has not been evaluated.[59904]

        Breast-feeding is not recommended during treatment with sacubitril; valsartan. There are no data on the presence of sacubitril or valsartan in human milk, the effects on the breastfed child, or the effects on milk production.[59904] Alternative therapies may be considered. Due to low concentrations in breast milk, guidelines generally consider the ACE inhibitors captopril and enalapril to be compatible with breast-feeding unless high doses are required.[63903] [68837] In addition, benazepril and quinapril are excreted in low quantities into breast milk and have been suggested as options during breast-feeding.[65551] [68835] [68836] If a patient is switched from sacubitril; valsartan to one of the alternative ACE inhibitors, allow a 36-hour washout period prior to starting the ACE inhibitor.[59904] Consider the benefits of breast-feeding, the risk of potential drug exposure to the breastfed child, and the risk of an untreated or inadequately treated condition.

        Mechanism of Action

        Sacubitril is a neprilysin inhibitor, and valsartan antagonizes angiotensin II at the AT1 receptor subtype. Neprilysin degrades endogenous vasoactive peptides, including natriuretic peptide, bradykinin, and adrenomedullin. Inhibition of neprilysin results in increased concentrations of these proteins and their activities, resulting in vasodilation, natriuresis, diuresis, and inhibition of pathologic growth and fibrosis. Inhibition of neprilysin occurs via the active metabolite of sacubitril, LBQ657. Angiotensin II is a potent vasoconstrictor and also stimulates the production and release of aldosterone.[59939][59940] The cardiovascular and renal effects of sacubitril; valsartan in patients with heart failure are due to increased concentrations of peptides that are degraded by neprilysin and the simultaneous inhibition of angiotensin II and angiotensin II-dependent aldosterone release by valsartan.[59904]

        Pharmacokinetics

        Sacubitril; valsartan is administered orally. Sacubitril and valsartan are highly bound to plasma proteins (more than 94%). Sacubitril is converted to its active metabolite, LBQ657, by plasma esterases and not further metabolized. Valsartan is minimally metabolized; approximately 20% of the dose is recovered as metabolites. A hydroxyl metabolite has been identified at low concentrations (less than 10%) in plasma. LBQ657 crosses the blood brain barrier to a minimal extent (0.28%). The average volume of distribution of sacubitril and valsartan is 103 and 75 L, respectively. After oral administration, 52% to 68% of sacubitril (primarily as metabolite) and approximately 13% of valsartan and its metabolites are excreted in urine. The remaining drug and metabolites are excreted in feces. Sacubitril, LBQ657, and valsartan exhibit a mean elimination half-life of approximately 1.4, 11.5, and 9.9 hours, respectively.[59904]

         

        In a 21-day study of patients with heart failure and reduced ejection fraction, sacubitril; valsartan administration resulted in significantly increased urine atrial natriuretic peptide (ANP) and cyclic guanosine monophosphate (cGMP) and plasma cGMP, and decreased plasma N-terminal pro b-type natriuretic peptide (NT-proBNP), aldosterone, and endothelin-1. Sacubitril; valsartan blocked the AT1-receptor resulting in increased plasma renin activity and plasma renin concentrations. In PARADIGM-HF, sacubitril; valsartan decreased NT-proBNP, increased BNP, and increased urine cGMP compared to enalapril. In the PARAMOUNT study that enrolled patients with heart failure with left ventricular ejection fraction (LVEF) of 45% or higher, sacubitril; valsartan (97 mg; 103 mg twice daily) decreased NT-proBNP by 17% compared to an 8% decrease with valsartan (160 mg twice daily) after 12 weeks of therapy. In the PARAGON-HF study, NT-proBNP was decreased by 24% at week 16 and 19% at week 48 in the sacubitril; valsartan group compared to 6% and 3%, respectively, in the valsartan group.[59904]

         

        Affected cytochrome P450 isoenzymes and drug transporters: CYP2C9, OATP1B1, OATP1B3, MRP2

        Valsartan does not inhibit CYP450 isoenzymes at clinically relevant concentrations. In vitro studies indicate CYP2C9 is the isoenzyme responsible for the formation of valeryl-4-hydroxy valsartan. An in vitro study with human liver tissue indicates that it is a substrate of the hepatic uptake transporter OATP1B1 and the hepatic efflux transporter MRP2.[29130][62719] In vitro data also indicate that sacubitril inhibits OATP1B1 and OSTP1B3 transporters.[59904]

        Route-Specific Pharmacokinetics

        Oral Route

        After oral administration, the peak plasma concentrations of sacubitril, its metabolite, and valsartan are reached in 0.5, 2, and 1.5 hours, respectively. Oral absolute bioavailability of sacubitril is estimated to be 60% or more. Valsartan when combined in the sacubitril; valsartan combination product is more bioavailable than valsartan in other marketed tablet formulations; 26 mg, 51 mg, and 103 mg of valsartan in sacubitril; valsartan is equivalent to 40 mg, 80 mg, and 160 mg of valsartan in other marketed formulations. Steady state concentrations of sacubitril, its metabolite, and valsartan are reached in 3 days. At steady state, sacubitril and valsartan do not accumulate; however, the metabolite of sacubitril accumulates by 1.6-fold. Food has no clinically significant effect on the systemic exposure of sacubitril; valsartan.[59904]

        Special Populations

        Hepatic Impairment

        • Sacubitril: The exposure of LBQ657 is increased approximately 2-fold in those with moderate hepatic impairment compared to healthy volunteers.[59904]
        • Valsartan: Patients with mild to moderate chronic hepatic disease have a 2-fold increase in the AUC of valsartan compared to healthy volunteers.[29130][59904]

        Renal Impairment

        • Sacubitril: The exposure of LBQ657 is increased approximately 3-fold in those with severe renal impairment compared to healthy volunteers.[59904]
        • Valsartan: There is no apparent correlation between renal function and valsartan exposure in patients with varying degrees of renal impairment.[29130][59904]

        Pediatrics

        The exposure to sacubitril; valsartan is similar in pediatric and adult patients.[59904]

        Geriatric

        No relevant pharmacokinetic differences have been observed for sacubitril; valsartan in patients 65 years and older compared to the overall population.[59904]

        Gender Differences

        Gender does not have a clinically significant effect on the systemic exposure of sacubitril or valsartan.[59904]

        Pregnancy/Breast-feeding

        pregnancy

        When pregnancy is detected, discontinue sacubitril; valsartan as soon as possible and consider alternative therapy. If sacubitril; valsartan must be used during pregnancy, advise pregnant patients of the potential risk of fetal harm. When used during the second and third trimesters of pregnancy, drugs that affect the renin-angiotensin system (e.g., ACE inhibitors, angiotensin II receptor antagonists) can cause reduced fetal renal function and increased fetal and neonatal morbidity and death. Use of drugs that affect the renin-angiotensin system during pregnancy can cause fetal death or injury such as hypotension, neonatal skull hypoplasia, reversible or irreversible renal failure and death. Anhydramnios and oligohydramnios have also been reported. Development of oligohydramnios may be associated with decreased fetal renal function leading to anuria and renal failure and results in fetal limb contractures, craniofacial deformation, hypotension, hypoplastic lung development, and death.[59904] An observational cohort study evaluating the outcomes of angiotensin receptor blockers (ARBs) use during the first trimester of pregnancy found an increased rate of major birth defects compared to non-hypertensive pregnancies, 5.4% and 3%, respectively; the difference did not reach statistical significance. The authors noted that there was a higher risk of major birth defects with ARB therapy beyond 6 weeks of gestation compared to discontinuation of ARBs before week 6, 7.3% and 2.8%, respectively. The rates of prematurity and reduced birth weight were also increased in the ARB group. There were no statistically significant differences in the rates of major birth defects, spontaneous abortions, or preterm births between women with chronic hypertension treated with an ARB versus methyldopa.[64367] Once pregnancy is detected, perform ultrasound examination if sacubitril; valsartan exposure occurs beyond the first trimester. In rare cases, when another antihypertensive agent cannot be used to treat a pregnant patient, perform serial ultrasound examinations to assess the intraamniotic environment. If oligohydramnios occurs, discontinue sacubitril; valsartan unless it is life-saving to the mother. It should be noted that oligohydramnios may not appear until after the fetus has sustained an irreversible injury. Closely observe newborns with histories of in utero exposure to sacubitril; valsartan for hypotension, oliguria, and hyperkalemia. If oliguria occurs, blood pressure and renal perfusion support may be required, as well as exchange transfusion or dialysis to reverse hypotension and/or support decreased renal function. The effect of sacubitril; valsartan on labor and delivery has not been evaluated.[59904]

        breast-feeding

        Breast-feeding is not recommended during treatment with sacubitril; valsartan. There are no data on the presence of sacubitril or valsartan in human milk, the effects on the breastfed child, or the effects on milk production.[59904] Alternative therapies may be considered. Due to low concentrations in breast milk, guidelines generally consider the ACE inhibitors captopril and enalapril to be compatible with breast-feeding unless high doses are required.[63903] [68837] In addition, benazepril and quinapril are excreted in low quantities into breast milk and have been suggested as options during breast-feeding.[65551] [68835] [68836] If a patient is switched from sacubitril; valsartan to one of the alternative ACE inhibitors, allow a 36-hour washout period prior to starting the ACE inhibitor.[59904] Consider the benefits of breast-feeding, the risk of potential drug exposure to the breastfed child, and the risk of an untreated or inadequately treated condition.

        Acarbose: (Moderate) Angiotensin II receptor antagonists (ARBs) may enhance the hypoglycemic effects of antidiabetic agents by improving insulin sensitivity. In addition, angiotensin II receptor antagonists have been associated with a reduced incidence in the development of new-onset diabetes in patients with hypertension or other cardiac disease. Patients receiving an ARB in combination with antidiabetic agents should be monitored for changes in glycemic control. [33489] [42591] Acetaminophen; Chlorpheniramine; Dextromethorphan; Phenylephrine: (Moderate) The cardiovascular effects of sympathomimetics may reduce the antihypertensive effects produced by angiotensin II receptor antagonists. Well-controlled hypertensive patients receiving phenylephrine at recommended doses do not appear at high risk for significant elevations in blood pressure; however, increased blood pressure (especially systolic hypertension) has been reported in some patients. [24172] [26181] [27369] Acetaminophen; Chlorpheniramine; Dextromethorphan; Pseudoephedrine: (Moderate) The cardiovascular effects of pseudoephedrine may reduce the antihypertensive effects produced by angiotensin II receptor antagonists. Monitor heart rate and blood pressure. [26181] [29548] Acetaminophen; Chlorpheniramine; Phenylephrine : (Moderate) The cardiovascular effects of sympathomimetics may reduce the antihypertensive effects produced by angiotensin II receptor antagonists. Well-controlled hypertensive patients receiving phenylephrine at recommended doses do not appear at high risk for significant elevations in blood pressure; however, increased blood pressure (especially systolic hypertension) has been reported in some patients. [24172] [26181] [27369] Acetaminophen; Dextromethorphan; Guaifenesin; Phenylephrine: (Moderate) The cardiovascular effects of sympathomimetics may reduce the antihypertensive effects produced by angiotensin II receptor antagonists. Well-controlled hypertensive patients receiving phenylephrine at recommended doses do not appear at high risk for significant elevations in blood pressure; however, increased blood pressure (especially systolic hypertension) has been reported in some patients. [24172] [26181] [27369] Acetaminophen; Dextromethorphan; Guaifenesin; Pseudoephedrine: (Moderate) The cardiovascular effects of pseudoephedrine may reduce the antihypertensive effects produced by angiotensin II receptor antagonists.

Well-controlled hypertensive patients receiving phenylephrine at recommended doses do not appear at high risk for significant elevations in blood pressure; however, increased blood pressure (especially systolic hypertension) has been reported in some patients. [24172] [26181] [27369] Acetaminophen; Ibuprofen: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible. [27388] [27991] [28608] [29130] [32122] [60860] Acetaminophen; Phenylephrine: (Moderate) The cardiovascular effects of sympathomimetics may reduce the antihypertensive effects produced by angiotensin II receptor antagonists. Well-controlled hypertensive patients receiving phenylephrine at recommended doses do not appear at high risk for significant elevations in blood pressure; however, increased blood pressure (especially systolic hypertension) has been reported in some patients. [24172] [26181] [27369] Acetaminophen; Pseudoephedrine: (Moderate) The cardiovascular effects of pseudoephedrine may reduce the antihypertensive effects produced by angiotensin II receptor antagonists. Monitor heart rate and blood pressure. [26181] [29548] Acrivastine; Pseudoephedrine: (Moderate) The cardiovascular effects of pseudoephedrine may reduce the antihypertensive effects produced by angiotensin II receptor antagonists. Monitor heart rate and blood pressure. [26181] [29548] Alemtuzumab: (Moderate) Alemtuzumab may cause hypotension. Careful monitoring of blood pressure and hypotensive symptoms is recommended especially in patients with ischemic heart disease and in patients on antihypertensive agents. [27942] Aliskiren: (Major) Aliskiren-containing products are contraindicated in combination with angiotensin II receptor antagonists (ARBs) in patients with diabetes mellitus. In general, avoid combined use of two renin-angiotensin-aldosterone system (RAAS) inhibitors, particularly in patients with CrCl less than 60 mL/minute. Combination therapy increases the risk for hyperkalemia, renal impairment, hypotension, and other side effects. Most patients receiving a comination of two RAAS inhibitors, such as ARBs and aliskiren, do not obtain any additional benefit compared to monotherapy. Closely monitor blood pressure, renal function, and electrolytes if aliskiren must be combined with another RAAS inhibitor. In the ALTITUDE trial, patients with type 2 diabetes and renal impairment, a population at high risk for cardiovascular and renal events, were given aliskiren in addition to ACE inhibitors or ARBs. The trial was stopped early because aliskiren was associated with an increased risk of non-fatal stroke, renal complications, hyperkalemia, and hypotension. In the Veterans Affairs Nephropathy in Diabetes (VA NEPHRON-D) trial, no additional benefit over monotherapy was seen in patients receiving the combination of losartan and lisinopril compared to monotherapy; however, there was an increased incidence of hyperkalemia and acute renal injury. [29130] [29132] [32198] [33200] [60860] [63923] Aliskiren; Hydrochlorothiazide, HCTZ: (Major) Aliskiren-containing products are contraindicated in combination with angiotensin II receptor antagonists (ARBs) in patients with diabetes mellitus. In general, avoid combined use of two renin-angiotensin-aldosterone system (RAAS) inhibitors, particularly in patients with CrCl less than 60 mL/minute. Combination therapy increases the risk for hyperkalemia, renal impairment, hypotension, and other side effects. Most patients receiving a comination of two RAAS inhibitors, such as ARBs and aliskiren, do not obtain any additional benefit compared to monotherapy.

In the Veterans Affairs Nephropathy in Diabetes (VA NEPHRON-D) trial, no additional benefit over monotherapy was seen in patients receiving the combination of losartan and lisinopril compared to monotherapy; however, there was an increased incidence of hyperkalemia and acute renal injury. [29130] [29132] [32198] [33200] [60860] [63923] Alogliptin; Metformin: (Moderate) Monitor blood glucose during concomitant metformin and angiotensin receptor blocker use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia. [32198] [42591] Alogliptin; Pioglitazone: (Moderate) Monitor blood glucose during concomitant thiazolidinedione and angiotensin receptor blocker use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia. [32198] [42591] Alpha-glucosidase Inhibitors: (Moderate) Angiotensin II receptor antagonists (ARBs) may enhance the hypoglycemic effects of antidiabetic agents by improving insulin sensitivity. In addition, angiotensin II receptor antagonists have been associated with a reduced incidence in the development of new-onset diabetes in patients with hypertension or other cardiac disease. Patients receiving an ARB in combination with antidiabetic agents should be monitored for changes in glycemic control. [33489] [42591] Alprostadil: (Minor) The concomitant use of systemic alprostadil injection and antihypertensive agents, such as angiotensin II receptor antagonists (angiotensin receptor blockers, or ARBs), may cause additive hypotension. Caution is advised with this combination. Systemic drug interactions with the urethral suppository (MUSE) or alprostadil intracavernous injection are unlikely in most patients because low or undetectable amounts of the drug are found in the peripheral venous circulation following administration. In those men with significant corpora cavernosa venous leakage, hypotension might be more likely. Use caution with in-clinic dosing for erectile dysfunction (ED) and monitor for the effects on blood pressure. However, in clinical trials with alprostadil intracavernous injection, anti-hypertensive agents had no apparent effect on the safety and efficacy of alprostadil. [30847] [30849] [55990] Amifostine: (Major) Patients receiving angiotensin II receptor antagonists should be closely monitored during amifostine infusions due to additive effects. Patients receiving amifostine at doses recommended for chemotherapy should have antihypertensive therapy interrupted 24 hours preceding administration of amifostine. If the antihypertensive cannot be stopped, patients should not receive amifostine. [49124] Amiloride: (Major) Potassium-sparing diuretics, such as amiloride, should be used with caution in patients taking drugs that may increase serum potassium levels such as angiotensin II receptor antagonists. Concurrent use can cause hyperkalemia, especially in elderly patients or patients with impaired renal function. Coadministration may also result in increases in serum creatinine in heart failure patients. [29135] [43532] [60860] Amiloride; Hydrochlorothiazide, HCTZ: (Major) Potassium-sparing diuretics, such as amiloride, should be used with caution in patients taking drugs that may increase serum potassium levels such as angiotensin II receptor antagonists. Concurrent use can cause hyperkalemia, especially in elderly patients or patients with impaired renal function. Coadministration may also result in increases in serum creatinine in heart failure patients. [29135] [43532] [60860] Amlodipine; Benazepril: (Contraindicated) Sacubitril; valsartan is contraindicated with the concomitant use of angiotensin-converting enzyme inhibitors (ACE inhibitors) due to the increased risk of angioedema. Do not administer sacubitril; valsartan within 36 hours of switching to or from an ACE inhibitor. [59904] (Major) In general, avoid combined use of angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs) due to lack of benefit with concomitant use in most patients. Closely monitor blood pressure, renal function, and electrolytes in patients on ACE inhibitors and ARBs. Dual blockade of the renin-angiotensin system with ACE inhibitors and ARBs is associated with increased risks of hypotension, syncope, hyperkalemia, and changes in renal function, including acute renal failure, compared to monotherapy. [27991] [28608] [29147] [34997] [34998] [63923] Amlodipine; Celecoxib: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible. [27388] [27991] [28608] [29130] [32122] [60860] Amobarbital: (Moderate) Concurrent use of amobarbital with antihypertensive agents may lead to hypotension. Monitor for decreases in blood pressure during times of coadministration. [6532] Amphetamine: (Minor) Amphetamines increase both systolic and diastolic blood pressure and may counteract the activity of some antihypertensive agents, such as angiotensin II receptor antagonists. Close monitoring of blood pressure is advised. [29332] [53320] [60070] Amphetamine; Dextroamphetamine Salts: (Minor) Amphetamines increase both systolic and diastolic blood pressure and may counteract the activity of some antihypertensive agents, such as angiotensin II receptor antagonists. Close monitoring of blood pressure is advised. [29332] [53320] [60070] Amphetamine; Dextroamphetamine: (Minor) Amphetamines increase both systolic and diastolic blood pressure and may counteract the activity of some antihypertensive agents, such as angiotensin II receptor antagonists. Close monitoring of blood pressure is advised. [29332] [53320] [60070] Angiotensin II: (Moderate) Angiotensin II receptor antagonists (angiotensin receptor blockers, or ARBs) may decrease the response to angiotensin II. Angiotensin II is a naturally occurring peptide hormone of the renin-angiotensin-aldosterone system (RAAS) that causes vasoconstriction and an increase in blood pressure. ARBs block the vasoconstrictor and aldosterone-secreting effects of angiotensin II by selectively blocking the binding of angiotensin II to the angiotensin receptor in many tissues. [62722] Angiotensin-converting enzyme inhibitors: (Contraindicated) Sacubitril; valsartan is contraindicated with the concomitant use of angiotensin-converting enzyme inhibitors (ACE inhibitors) due to the increased risk of angioedema. Do not administer sacubitril; valsartan within 36 hours of switching to or from an ACE inhibitor. [59904] (Major) In general, avoid combined use of angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs) due to lack of benefit with concomitant use in most patients. Closely monitor blood pressure, renal function, and electrolytes in patients on ACE inhibitors and ARBs. Dual blockade of the renin-angiotensin system with ACE inhibitors and ARBs is associated with increased risks of hypotension, syncope, hyperkalemia, and changes in renal function, including acute renal failure, compared to monotherapy. [27991] [28608] [29147] [34997] [34998] [63923] Apomorphine: (Moderate) Use of angiotensin II receptor antagonists and apomorphine together can increase the hypotensive effects of apomorphine. Monitor blood pressure regularly during use of this combination. [28661] Apraclonidine: (Minor) Alpha blockers as a class may reduce heart rate and blood pressure. While no specific drug interactions have been identified with systemic agents and apraclonidine during clinical trials, it is theoretically possible that additive blood pressure reductions could occur when apraclonidine is combined with the use of antihypertensive agents. Patients using cardiovascular drugs concomitantly with apraclonidine should have their pulse and blood pressure monitored periodically. [6224] Aprepitant, Fosaprepitant: (Minor) Use caution if valsartan and aprepitant are used concurrently and monitor for a possible decrease in the efficacy of valsartan. After administration, fosaprepitant is rapidly converted to aprepitant and shares the same drug interactions. Valsartan is a CYP2C9 substrate and aprepitant is a CYP2C9 inducer. Administration of a CYP2C9 substrate, tolbutamide, on days 1, 4, 8, and 15 with a 3-day regimen of oral aprepitant (125 mg/80 mg/80 mg) decreased the tolbutamide AUC by 23% on day 4, 28% on day 8, and 15% on day 15. The AUC of tolbutamide was decreased by 8% on day 2, 16% on day 4, 15% on day 8, and 10% on day 15 when given prior to oral administration of aprepitant 40 mg on day 1, and on days 2, 4, 8, and 15. The effects of aprepitant on tolbutamide were not considered significant. When a 3-day regimen of aprepitant (125 mg/80 mg/80 mg) given to healthy patients on stabilized chronic warfarin therapy (another CYP2C9 substrate), a 34% decrease in S-warfarin trough concentrations was noted, accompanied by a 14% decrease in the INR at five days after completion of aprepitant. [29130] [30676] [34686] [40027] Aripiprazole: (Minor) Aripiprazole may enhance the hypotensive effects of antihypertensive agents. [31327] Articaine; Epinephrine: (Moderate) Antihypertensives, including angiotensin II receptor antagonists, antagonize the vasopressor effects of parenteral epinephrine. [56575] Asenapine: (Moderate) Secondary to alpha-blockade, asenapine can produce vasodilation that may result in additive effects during concurrent use of antihypertensive agents. The potential reduction in blood pressure can precipitate orthostatic hypotension and associated dizziness, tachycardia, and syncope. If concurrent use of asenapine and antihypertensive agents is necessary, patients should be counseled on measures to prevent orthostatic hypotension, such as sitting on the edge of the bed for several minutes prior to standing in the morning and rising slowly from a seated position. Close monitoring of blood pressure is recommended until the full effects of the combination therapy are known. [36343] Atazanavir: (Moderate) Concurrent use of atazanavir with valsartan may result in elevated valsartan serum concentrations. Valsartan is a substrate for the drug transporter organic anion transporting polypeptide (OATP1B1/1B3); atazanavir is an OATP1B1 inhibitor. Monitor for increased toxicities if these drugs are given together. [56579] [61511] [61512] Atazanavir; Cobicistat: (Moderate) Concurrent use of atazanavir with valsartan may result in elevated valsartan serum concentrations. Valsartan is a substrate for the drug transporter organic anion transporting polypeptide (OATP1B1/1B3); atazanavir is an OATP1B1 inhibitor. Monitor for increased toxicities if these drugs are given together. [56579] [61511] [61512] (Minor) Caution is warranted when cobicistat is administered with valsartan as there is a potential for increased valsartan concentrations. Valsartan is a substrate of organic anion transporting polypeptide (OATP)1B1. Cobicistat is an inhibitor of OATP. [29130] [35588] [51664] [58000] [60860] Baclofen: (Moderate) Baclofen has been associated with hypotension. Concurrent use with baclofen and antihypertensive agents may result in additive hypotension. Dosage adjustments of the antihypertensive medication may be required. [30582] [57272] Benazepril: (Contraindicated) Sacubitril; valsartan is contraindicated with the concomitant use of angiotensin-converting enzyme inhibitors (ACE inhibitors) due to the increased risk of angioedema. Do not administer sacubitril; valsartan within 36 hours of switching to or from an ACE inhibitor. [59904] (Major) In general, avoid combined use of angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs) due to lack of benefit with concomitant use in most patients. Closely monitor blood pressure, renal function, and electrolytes in patients on ACE inhibitors and ARBs. Dual blockade of the renin-angiotensin system with ACE inhibitors and ARBs is associated with increased risks of hypotension, syncope, hyperkalemia, and changes in renal function, including acute renal failure, compared to monotherapy. [27991] [28608] [29147] [34997] [34998] [63923] Benazepril; Hydrochlorothiazide, HCTZ: (Contraindicated) Sacubitril; valsartan is contraindicated with the concomitant use of angiotensin-converting enzyme inhibitors (ACE inhibitors) due to the increased risk of angioedema. Do not administer sacubitril; valsartan within 36 hours of switching to or from an ACE inhibitor. [59904] (Major) In general, avoid combined use of angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs) due to lack of benefit with concomitant use in most patients. Closely monitor blood pressure, renal function, and electrolytes in patients on ACE inhibitors and ARBs. Dual blockade of the renin-angiotensin system with ACE inhibitors and ARBs is associated with increased risks of hypotension, syncope, hyperkalemia, and changes in renal function, including acute renal failure, compared to monotherapy. [27991] [28608] [29147] [34997] [34998] [63923] Benzphetamine: (Minor) Benzphetamine may increase both systolic and diastolic blood pressure and may counteract the activity of some antihypertensive agents, such as angiotensin II receptor antagonists. Close monitoring of blood pressure is advised. [28456] [28477] Bexagliflozin: (Moderate) Monitor blood glucose during concomitant SGLT2 inhibitor and angiotensin receptor blocker use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia. [32198] [42591] Brexpiprazole: (Moderate) Due to brexpiprazole's antagonism at alpha 1-adrenergic receptors, the drug may enhance the hypotensive effects of alpha-blockers and other antihypertensive agents. [59949] Brompheniramine; Dextromethorphan; Phenylephrine: (Moderate) The cardiovascular effects of sympathomimetics may reduce the antihypertensive effects produced by angiotensin II receptor antagonists. Well-controlled hypertensive patients receiving phenylephrine at recommended doses do not appear at high risk for significant elevations in blood pressure; however, increased blood pressure (especially systolic hypertension) has been reported in some patients. [24172] [26181] [27369] Brompheniramine; Phenylephrine: (Moderate) The cardiovascular effects of sympathomimetics may reduce the antihypertensive effects produced by angiotensin II receptor antagonists. Well-controlled hypertensive patients receiving phenylephrine at recommended doses do not appear at high risk for significant elevations in blood pressure; however, increased blood pressure (especially systolic hypertension) has been reported in some patients. [24172] [26181] [27369] Brompheniramine; Pseudoephedrine: (Moderate) The cardiovascular effects of pseudoephedrine may reduce the antihypertensive effects produced by angiotensin II receptor antagonists. Monitor heart rate and blood pressure. [26181] [29548] Brompheniramine; Pseudoephedrine; Dextromethorphan: (Moderate) The cardiovascular effects of pseudoephedrine may reduce the antihypertensive effects produced by angiotensin II receptor antagonists. Monitor heart rate and blood pressure. [26181] [29548] Bumetanide: (Moderate) Coadministration of furosemide and Angiotensin-converting enzyme inhibitors (ACE inhibitors) or angiotensin II receptor antagonists may result in severe hypotension and deterioration in renal function, including renal failure. Hyponatremia or hypovolemia predisposes patients to acute hypotensive episodes following initiation of ACE inhibitor therapy. While ACE inhibitors and loop diuretics are routinely administered together in the treatment of heart failure, if an ACE inhibitor is to be administered to a patient receiving furosemide, initial doses should be conservative. [28429] [48546] Bupivacaine; Epinephrine: (Moderate) Antihypertensives, including angiotensin II receptor antagonists, antagonize the vasopressor effects of parenteral epinephrine. [56575] Bupivacaine; Meloxicam: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible. [27388] [27991] [28608] [29130] [32122] [60860] Cabergoline: (Moderate) Cabergoline should be used cautiously with antihypertensive agents, including angiotensin II receptor antagonists. Cabergoline has been associated with hypotension. Initial doses of cabergoline higher than 1 mg may produce orthostatic hypotension. It may be advisable to monitor blood pressure. [27964] Calcium Phosphate, Supersaturated: (Moderate) Concomitant use of medicines with potential to alter renal perfusion or function such as angiotensin II receptor antagonists, may increase the risk of acute phosphate nephropathy in patients taking sodium phosphate monobasic monohydrate; sodium phosphate dibasic anhydrous. [32159] [32160] Canagliflozin: (Moderate) Monitor blood glucose during concomitant SGLT2 inhibitor and angiotensin receptor blocker use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia. [32198] [42591] Canagliflozin; Metformin: (Moderate) Monitor blood glucose during concomitant metformin and angiotensin receptor blocker use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia. [32198] [42591] (Moderate) Monitor blood glucose during concomitant SGLT2 inhibitor and angiotensin receptor blocker use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia. [32198] [42591] Captopril: (Contraindicated) Sacubitril; valsartan is contraindicated with the concomitant use of angiotensin-converting enzyme inhibitors (ACE inhibitors) due to the increased risk of angioedema. Do not administer sacubitril; valsartan within 36 hours of switching to or from an ACE inhibitor. [59904] (Major) In general, avoid combined use of angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs) due to lack of benefit with concomitant use in most patients. Closely monitor blood pressure, renal function, and electrolytes in patients on ACE inhibitors and ARBs. Dual blockade of the renin-angiotensin system with ACE inhibitors and ARBs is associated with increased risks of hypotension, syncope, hyperkalemia, and changes in renal function, including acute renal failure, compared to monotherapy. [27991] [28608] [29147] [34997] [34998] [63923] Captopril; Hydrochlorothiazide, HCTZ: (Contraindicated) Sacubitril; valsartan is contraindicated with the concomitant use of angiotensin-converting enzyme inhibitors (ACE inhibitors) due to the increased risk of angioedema. Do not administer sacubitril; valsartan within 36 hours of switching to or from an ACE inhibitor. [59904] (Major) In general, avoid combined use of angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs) due to lack of benefit with concomitant use in most patients. Closely monitor blood pressure, renal function, and electrolytes in patients on ACE inhibitors and ARBs. Dual blockade of the renin-angiotensin system with ACE inhibitors and ARBs is associated with increased risks of hypotension, syncope, hyperkalemia, and changes in renal function, including acute renal failure, compared to monotherapy. [27991] [28608] [29147] [34997] [34998] [63923] Carbidopa; Levodopa: (Moderate) Concomitant use of antihypertensive agents with levodopa can result in additive hypotensive effects. [28521] Carbidopa; Levodopa; Entacapone: (Moderate) Concomitant use of antihypertensive agents with levodopa can result in additive hypotensive effects. [28521] Cariprazine: (Moderate) Orthostatic vital signs should be monitored in patients who are at risk for hypotension, such as those receiving cariprazine in combination with antihypertensive agents. Atypical antipsychotics may cause orthostatic hypotension and syncope, most commonly during treatment initiation and dosage increases. Patients should be informed about measures to prevent orthostatic hypotension, such as sitting on the edge of the bed for several minutes prior to standing in the morning, or rising slowly from a seated position. Consider a cariprazine dose reduction if hypotension occurs. [60164] Celecoxib: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible. [27388] [27991] [28608] [29130] [32122] [60860] Celecoxib; Tramadol: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible. [27388] [27991] [28608] [29130] [32122] [60860] Cetirizine; Pseudoephedrine: (Moderate) The cardiovascular effects of pseudoephedrine may reduce the antihypertensive effects produced by angiotensin II receptor antagonists. Monitor heart rate and blood pressure. [26181] [29548] Chlophedianol; Dexchlorpheniramine; Pseudoephedrine: (Moderate) The cardiovascular effects of pseudoephedrine may reduce the antihypertensive effects produced by angiotensin II receptor antagonists. Monitor heart rate and blood pressure. [26181] [29548] Chloroprocaine: (Moderate) Local anesthetics may cause additive hypotension in combination with antihypertensive agents. [28996] Chlorpheniramine; Dextromethorphan; Phenylephrine: (Moderate) The cardiovascular effects of sympathomimetics may reduce the antihypertensive effects produced by angiotensin II receptor antagonists. Well-controlled hypertensive patients receiving phenylephrine at recommended doses do not appear at high risk for significant elevations in blood pressure; however, increased blood pressure (especially systolic hypertension) has been reported in some patients.

[26181] [29548] Citric Acid; Potassium Citrate; Sodium Citrate: (Moderate) Monitor serum potassium concentrations closely if potassium supplements and angiotensin II receptor antagonists are used together. Concomitant use may increase the risk of hyperkalemia. [28608] [29130] [30272] [57713] Clofarabine: (Moderate) Concomitant use of clofarabine, a substrate of OAT1 and OAT3, and valsartan, an inhibitor of OAT protein (OATP), may result in increased clofarabine levels. Therefore, monitor for signs of clofarabine toxicity such as gastrointestinal toxicity (e.g., nausea, vomiting, diarrhea, mucosal inflammation), hematologic toxicity, and skin toxicity (e.g., hand and foot syndrome, rash, pruritus) in patients also receiving valsartan. [29130] [54578] Clozapine: (Moderate) Clozapine used concomitantly with the antihypertensive agents can increase the risk and severity of hypotension by potentiating the effect of the antihypertensive drug. [28262] Cobicistat: (Minor) Caution is warranted when cobicistat is administered with valsartan as there is a potential for increased valsartan concentrations. Valsartan is a substrate of organic anion transporting polypeptide (OATP)1B1. Cobicistat is an inhibitor of OATP. [29130] [35588] [51664] [58000] [60860] Cocaine: (Major) Use of cocaine with antihypertensive agents may increase the antihypertensive effects of the antihypertensive medications or may potentiate cocaine-induced sympathetic stimulation.

[24172] [26181] [27369] Co-Enzyme Q10, Ubiquinone: (Moderate) Co-enzyme Q10, ubiquinone (CoQ10) may lower blood pressure. CoQ10 use in combination with antihypertensive agents may lead to additional reductions in blood pressure in some individuals. Patients who choose to take CoQ10 concurrently with antihypertensive medications should receive periodic blood pressure monitoring. Patients should be advised to inform their prescriber of their use of CoQ10. [34900] Cyclosporine: (Moderate) Coadministration of cyclosporine and an angiotensin II receptor antagonist, like valsartan, may increase the risk of hyperkalemia and reduced renal function. In response to cyclosporine-induced renal afferent vasoconstriction and glomerular hypoperfusion, angiotensin II is required to maintain an adequate glomerular filtration rate. Inhibition of angiotensin-converting enzyme (ACE) could reduce renal function acutely. Several cases of acute renal failure have been associated with the addition of enalapril to cyclosporine therapy in renal transplant patients. Also, cyclosporine can cause hyperkalemia, and inhibition of angiotensin II leads to reduced aldosterone concentrations, which can increase the serum potassium concentration. Closely monitor renal function and serum potassium concentrations in patients receiving cyclosporine concurrently with valsartan. Additionally, valsartan is a substrate of the hepatic uptake transporter OATP1B1 and cyclosporine is an inhibitor of OATP. Coadministration may increase systemic exposure to valsartan.

Monitor heart rate and blood pressure. [26181] [29548] Dextromethorphan; Quinidine: (Moderate) Quinidine can decrease blood pressure and should be used cautiously in patients receiving antihypertensive agents due to the potential for additive hypotension. [28249] Diazoxide: (Moderate) Additive hypotensive effects can occur with the concomitant administration of diazoxide with other antihypertensive agents. This interaction can be therapeutically advantageous, but dosages must be adjusted accordingly. The manufacturer advises that IV diazoxide should not be administered to patients within 6 hours of receiving beta-blockers, hydralazine, methyldopa, minoxidil, nitrites, prazosin, reserpine, or other antihypertensive agents. [29537] Diclofenac: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use.

[28429] [48546] Trandolapril: (Contraindicated) Sacubitril; valsartan is contraindicated with the concomitant use of angiotensin-converting enzyme inhibitors (ACE inhibitors) due to the increased risk of angioedema. Do not administer sacubitril; valsartan within 36 hours of switching to or from an ACE inhibitor. [59904] (Major) In general, avoid combined use of angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs) due to lack of benefit with concomitant use in most patients. Closely monitor blood pressure, renal function, and electrolytes in patients on ACE inhibitors and ARBs. Dual blockade of the renin-angiotensin system with ACE inhibitors and ARBs is associated with increased risks of hypotension, syncope, hyperkalemia, and changes in renal function, including acute renal failure, compared to monotherapy. [27991] [28608] [29147] [34997] [34998] [63923] Trandolapril; Verapamil: (Contraindicated) Sacubitril; valsartan is contraindicated with the concomitant use of angiotensin-converting enzyme inhibitors (ACE inhibitors) due to the increased risk of angioedema. Do not administer sacubitril; valsartan within 36 hours of switching to or from an ACE inhibitor. [59904] (Major) In general, avoid combined use of angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs) due to lack of benefit with concomitant use in most patients. Closely monitor blood pressure, renal function, and electrolytes in patients on ACE inhibitors and ARBs. Dual blockade of the renin-angiotensin system with ACE inhibitors and ARBs is associated with increased risks of hypotension, syncope, hyperkalemia, and changes in renal function, including acute renal failure, compared to monotherapy. [27991] [28608] [29147] [34997] [34998] [63923] Tranylcypromine: (Contraindicated) The use of hypotensive agents and tranylcypromine is contraindicated by the manufacturer of tranylcypromine because the effects of hypotensive agents may be markedly potentiated. [29656] Trazodone: (Minor) Due to additive hypotensive effects, patients receiving antihypertensive agents concurrently with trazodone may have excessive hypotension. Decreased dosage of the antihypertensive agent may be required when given with trazodone. [28719] Triamterene: (Moderate) Monitor serum potassium concentrations in patients receiving angiotensin II receptor antagonists concomitantly with triamterene. Concomitant use may result in hyperkalemia. [28608] [29160] [60860] Triamterene; Hydrochlorothiazide, HCTZ: (Moderate) Monitor serum potassium concentrations in patients receiving angiotensin II receptor antagonists concomitantly with triamterene. Concomitant use may result in hyperkalemia. [28608] [29160] [60860] Trimethoprim: (Moderate) Monitor for hyperkalemia if concomitant use of an angiotensin II receptor antagonist and trimethoprim is necessary. Avoid concomitant use and consider alternative antibiotic therapy in patients with additional risk factors for hyperkalemia, including patients older than 65 years, those with underlying disorders of potassium metabolism, renal insufficiency, or those requiring high doses of trimethoprim. Amongst patients older than 65 years, concomitant use has been associated with a 2- to 7-fold increased risk of significant hyperkalemia compared to other antibiotics. Trimethoprim has a potassium-sparing effect on the distal nephron and may induce hyperkalemia, especially in those with pre-existing risk factors. [43890] [55864] [67024] [67025] Vitamin B Complex Supplements: (Moderate) Cutaneous vasodilation induced by niacin may become problematic if high-dose niacin is used concomitantly with other antihypertensive agents. This effect is of particular concern in the setting of acute myocardial infarction, unstable angina, or other acute hemodynamic compromise. [44027] Zafirlukast: (Minor) In vitro data indicate that zafirlukast inhibits the CYP2C9 and CYP3A4 isoenzymes at concentrations close to the clinically achieved total plasma concentrations. Until more clinical data are available, zafirlukast should be used cautiously in patients stabilized on drugs metabolized by CYP2C9 such as valsartan. [28001] [28222] Ziprasidone: (Minor) Ziprasidone is a moderate antagonist of alpha-1 receptors and may cause orthostatic hypotension with or without tachycardia, dizziness, or syncope. Additive hypotensive effects are possible if ziprasidone is used concurrently with antihypertensive agents. [28233]
