Maraviroc is a substrate of P-glycoprotein (Pgp); nifedipine is a mild inhibitor of Pgp. It is possible that additive reductions in blood pressure may be seen when fish oils are used in a patient already taking antihypertensive agents. Monitor clinical response during coadministration; adjustment of nifedipine dosage may be needed during concurrent beta-blocker therapy. A gradual downward titration of the beta-adrenergic blocking agent dosage during initiation of nifedipine therapy may minimize or eliminate this potential interaction. Nifedipine is a CYP3A substrate, and lesinurad is a weak CYP3A inducer. Metoprolol: (Moderate) In general, concomitant therapy of nifedipine with beta-blockers is well tolerated and can even be beneficial in some cases (i.e., inhibition of nifedipine-induced reflex tachycardia by beta-blockade). Elderly patients may be at increased risk of adverse effects from combined long-term NSAID therapy and antihypertensive agents, especially diuretics, due to age-related decreases in renal function and an increased risk of stroke and coronary artery disease. Naproxen; Pseudoephedrine: (Moderate) If nonsteroidal anti-inflammatory drugs (NSAIDs) and an antihypertensive drug are concurrently used, carefully monitor the patient for signs and symptoms of renal insufficiency and blood pressure control. Lansoprazole; Naproxen: (Moderate) If nonsteroidal anti-inflammatory drugs (NSAIDs) and an antihypertensive drug are concurrently used, carefully monitor the patient for signs and symptoms of renal insufficiency and blood pressure control. In addition, both drugs can cause hypotension, and these effects can be additive. Careful monitoring of blood pressure is suggested during concurrent therapy of MAOIs with calcium-channel blockers. Finally, angina has been reported when beta-adrenergic blocking agents are withdrawn abruptly and nifedipine therapy is initiated. Semin Perinatol. Patients who rely upon renal prostaglandins to maintain renal perfusion may have acute renal blood flow reduction with NSAID usage. Hypotension and impaired cardiac performance can occur during coadministration of nifedipine with beta-blockers, especially in patients with left ventricular dysfunction, cardiac arrhythmias, or aortic stenosis. Nifedipine is a CYP3A4 substrate and ceritinib is a strong CYP3A4 inhibitor. Aldesleukin, IL-2: (Moderate) Calcium channel blockers may potentiate the hypotension seen with aldesleukin, IL 2. Nifedipine is used to treat hypertension (high blood pressure). Azithromycin may be preferred if the use of a macrolide antibiotic is necessary in a patient receiving nifedipine therapy. Free Online Library: COMPARISON OF ORAL NIFEDIPINE WITH INTRAVENOUS HYDRALAZINE FOR ACUTE HYPERTENSIVE EMERGENCIES OF PREGNANCY. This action may be additive with other agents that can cause hypotension such as calcium-channel blockers. Monitor clinical response during coadministration; adjustment of nifedipine dosage may be needed during concurrent beta-blocker therapy. Finally, angina has been reported when beta-adrenergic blocking agents are withdrawn abruptly and nifedipine therapy is initiated. PubMed 15. NSAIDs cause a dose-dependent reduction in prostaglandin formation, which may result in a reduction in renal blood flow leading to renal insufficiency and an increase in blood pressure that are often accompanied by peripheral edema and weight gain. Lower mean arterial pressure by 20- 25% or diastolic pressure to <100 to 110 mmHg within 30–60 minutes. Fexofenadine; Pseudoephedrine: (Moderate) The cardiovascular effects of pseudoephedrine may reduce the antihypertensive effects produced by calcium-channel blockers. Titrate milrinone dosage according to hemodynamic response. The side effects of … The same total daily dosage should apply when switching from immediate to extended-release preparations. A gradual downward titration of the beta-adrenergic blocking agent dosage during initiation of nifedipine therapy may minimize or eliminate this potential interaction. Monitor heart rate, blood pressure, and cardiac response. The immediate-release nifedipine dosage form is currently only indicated for the treatment of chronic stable angina or vasospastic angina. Saquinavir: (Moderate) According to the manufacturer of nifedipine, coadministration with saquinavir may result in increased exposure to nifedipine, and initiation of nifedipine should begin with the lowest available dose.

Houston, MD \s=b\Oral clonidine hydrochloride rapid titration or loading is a safe, effective method to control severe elevations of blood pressure in hypertensive crisis in many clinical situations. NSAIDs cause a dose-dependent reduction in prostaglandin formation, which may result in a reduction in renal blood flow leading to renal insufficiency and an increase in blood pressure that are often accompanied by peripheral edema and weight gain. A retrospective, case crossover study, found the risk of hospitalization due to hypotension or shock to be significantly increased in geriatric patients exposed to clarithromycin during concurrent calcium-channel blocker therapy (OR 3.7, 95% CI 2.3-6.1). Co-Enzyme Q10, Ubiquinone: (Moderate) Co-enzyme Q10, ubiquinone (CoQ10) may lower blood pressure. Elderly patients may be at increased risk of adverse effects from combined long-term NSAID therapy and antihypertensive agents, especially diuretics, due to age-related decreases in renal function and an increased risk of stroke and coronary artery disease. When used concomitantly, anesthetics and calcium-channel blockers should be titrated carefully to avoid excessive cardiovascular depression. In a pharmacokinetic study of 26 patients with solid tumors and normal renal and hepatic function, vincristine 2 mg IV was administered alone (n = 14) or with nifedipine 10 mg by mouth three times daily for 3 days before and 7 days after (n = 12). Patients who rely upon renal prostaglandins to maintain renal perfusion may have acute renal blood flow reduction with NSAID usage. NSAIDs, to varying degrees, have been associated with an elevation in blood pressure. The concurrent administration of antihypertensive agents and duloxetine may increase the risk of hypotension. Alfuzosin: (Moderate) The concomitant administration of alpha-blockers with other antihypertensive agents can cause additive hypotensive effects. -Maintenance dose: 30 to 90 mg orally once a day. There is little difference in the bioavailability when nifedipine capsules are swallowed whole or if they are bitten and swallowed, or bitten and held sublingually. Angioedema has been reported in patients taking mammalian target of rapamycin (mTOR) inhibitors in combination with another calcium channel blocker. Renal Dose Adjustments NSAIDs cause a dose-dependent reduction in prostaglandin formation, which may result in a reduction in renal blood flow leading to renal insufficiency and an increase in blood pressure that are often accompanied by peripheral edema and weight gain. A prospective observational study of the hemodynamic effects of oral nifedipine was conducted with severely preeclamptic patients receiving magnesium sulfate infusion during a hypertensive emergency. A gradual downward titration of the beta-adrenergic blocking agent dosage during initiation of nifedipine therapy may minimize or eliminate this potential interaction. Patients should be monitored for the desired cardiovascular effects on heart rate, chest pain, or blood pressure; nifedipine dosages may need to be adjusted while the patient is receiving pioglitazone. Monitor clinical response during coadministration; adjustment of nifedipine dosage may be needed during concurrent beta-blocker therapy. Diltiazem: (Moderate) Diltiazem has been reported to increase the plasma level and hypotensive effects of nifedipine via CYP3A4 inhibition. If coadministration is necessary, monitor the patient closely for desired cardiovascular effects on heart rate, blood pressure, or chest pain. A single dose of nifedipine (5 mg by the sublingual route) was prescribed to determine its effectiveness and safety in the treatment of hypertensive emergencies during haemodialysis. The increase in nifedipine bioavailability is most likely due to inhibition of the CYP3A4 isoenzyme, resulting in reduced first-pass drug metabolism. Azithromycin may be preferred if the use of a macrolide antibiotic is necessary in a patient receiving nifedipine therapy. Labetalol: (Moderate) In general, concomitant therapy of nifedipine with beta-blockers is well tolerated and can even be beneficial in some cases (i.e., inhibition of nifedipine-induced reflex tachycardia by beta-blockade). Although hypertensive emergencies can lead to significant mor-bidity and potentially fatal target-organ damage, only 1%–3% of patients with hypertension will have a hypertensive emergency during their lifetime (Deshmukh 2011). Hawthorn, Crataegus laevigata: (Moderate) Hawthorn, Crataegus laevigata (also known as C. oxyacantha) may potentially interact with antihypertensive, heart failure, or arrhythmia medications such as the calcium-channel blockers. Clinical trial registration: Max. Finally, angina has been reported when beta-adrenergic blocking agents are withdrawn abruptly and nifedipine therapy is initiated. The FDA-approved labeling for some nifedipine products contraindicates coadministration with strong CYP3A4 inducers, while other manufacturers classify the recommendation as a warning. 2017 Dec;217(6):687.e1-687.e6. This additive effect can be desirable, but the patient should be monitored carefully and the dosage should be adjusted based on clinical response. 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. In addition, coadministration for 7 days resulted in a 5% and 4% increase in pioglitazone AUC and Cmax, respectively. This is a professional level major reference work containing information, in A-Z format, on herb-drug, herb-supplement, herb -food and herb-laboratory test interactions; all of which is data referenced. hypertensive emergency. Hypotension and impaired cardiac performance can occur during coadministration of nifedipine with beta-blockers, especially in patients with left ventricular dysfunction, cardiac arrhythmias, or aortic stenosis. If coadministration is necessary, monitor the patient closely for desired cardiovascular effects on heart rate, blood pressure, or chest pain. There have also been reports of no significant change in quinidine concentrations or effect. Finally, angina has been reported when beta-adrenergic blocking agents are withdrawn abruptly and nifedipine therapy is initiated.
