GENERIC NAME: nicardipine
BRAND NAME: Cardene, Cardene SR
DRUG CLASS AND MECHANISM: Nicardipine belongs to a class of blood pressure reducing medications called calcium channel blockers (CCBs). Other medications in this class include diltiazem (Cardizem), amlodipine (Norvasc), felodipine (Plendil), verapamil (Calan, Isoptin), clevidipine (Cleviprex), and nifedipine (Adalat, Procardia). These medications block the movement of calcium into the smooth muscle cells surrounding the arteries of the body. Since calcium promotes contraction of muscle, blocking calcium entry into the muscle cells relaxes the arterial muscles and causes the arteries to become larger. This lowers blood pressure, which reduces the work that the heart must do to pump blood to the body. Reducing the work of the heart lessens the heart muscle's demand for oxygen and thereby helps prevent angina (heart pain) in patients with coronary artery disease. Unlike verapamil or diltiazem, nicardipine has little effect on heart muscle or on electrical conduction within the heart. The FDA approved nicardipine in December 1988.
GENERIC AVAILABLE: Yes
PREPARATIONS: Capsules: 20 and 30 mg; Sustained release capsules:30 and 60 mg; Injection 0.1, 0.2 and 2.5 mg
STORAGE: Nicardipine should be stored at room temperature, 15 to 30 C (59 to 86 F), and protected from light.
PRESCRIBED FOR: Oral nicardipine is used alone or in combination with other drugs for the treatment of high blood pressure. Conventional capsules (not sustained release) also are used for the treatment of angina (chest pain). Nicardipine injections are used for short-term treatment of blood pressure when oral medications are not possible or desirable.
DOSING: The recommended dose of nicardipine for treatment of hypertension is 20-40 mg three times daily with conventional capsules or 30-60 mg twice daily with sustained release capsules. Intravenous infusion rates can range between 0.5 and 15 mg/hr. Chest pain is treated with 20-40 mg of conventional capsules three times daily.
DRUG INTERACTIONS: Rifampin, phenobarbital, phenytoin (Dilantin, Dilantin-125), oxcarbazepine (suspension oral Trileptal; oral Trileptal) and carbamazepine (Tegretol, Tegretol XR , Equetro, Carbatrol) may reduce blood levels of nicardipine by increasing its metabolism (destruction) in the liver. Therapy should be monitored and drug doses should be adjusted accordingly when nicardipine is used with these drugs.
Co-administration of nicardipine and cyclosporine results in increased cyclosporine blood levels. Cyclosporine blood levels should be monitored and its dosage reduced when taking nicardipine.
