Time (minutes) and necessary doses were outlined to achieve blood pressure lower than 150/95 mmHg. Well-controlled hypertensive patients receiving decongestant sympathomimetics at recommended doses do not appear to be at high risk for significant elevations in blood pressure; however, increased blood pressure (especially systolic hypertension) has been reported in some patients. Belladonna Alkaloids; Ergotamine; Phenobarbital: (Major) Avoid coadministration of nifedipine with barbiturates and consider alternative therapy if possible. Efavirenz induces CYP3A4, potentially altering serum concentrations of calcium-channel blockers metabolized via CYP3A4. Metformin: (Minor) Nifedipine may increase the plasma metformin Cmax and AUC and increase the amount of metformin excreted in the urine. Level of evidence I. Not a Member? 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. Dose: 10-20 mg PO tid; Start: 10 mg PO tid, may incr. Extended-release preparations are available in 30, 60, and 90 mg tablets. Practical, fast, safe, and dependable control of hypertensive urgencies and emergencies has made sublingual nifedipine the treatment of choice of such pa tients in the Emergency Care Department. Finally, angina has been reported when beta-adrenergic blocking agents are withdrawn abruptly and nifedipine therapy is initiated. One study in patients with essential hypertension (n = 25) reported an average rise of 5 mmHg in mean blood pressure and a 66% increase in plasma norepinephrine (NE) concentrations following yohimbine administration (4 x 5.4 mg tablets PO). Coadministration of nifedipine with another strong CYP3A4 inducer reduced the AUC and Cmax of nifedipine by approximately 70%. Magnesium sulfate therapy should not be given concurrently because of additive effects on maternal cardiac function. Epub 2014 May 16. 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.

In addition, calcium-channel blockers with CYP3A4 inhibitory properties, such as diltiazem, nicardipine, and verapamil, may also reduce the hepatic metabolism of ergonovine and increase the risk of ergot toxicity. Concomitant administration of prazosin with other antihypertensive agents is not prohibited, however. Vermillion ST, Scardo JA, Newman RB, Chauhan SP. Aprepitant, when administered as a 3-day oral regimen (125 mg/80 mg/80 mg), is a moderate CYP3A4 inhibitor and inducer and may increase plasma concentrations of nifedipine. 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. 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. 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).
