CARDENE SR vs PROCARDIA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nicardipine is a dihydropyridine calcium channel blocker that inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle. It produces relaxation of coronary vascular smooth muscle and dilation of coronary arteries, and also dilates peripheral arteries, reducing systemic vascular resistance and blood pressure.
Dihydropyridine calcium channel blocker that inhibits the influx of calcium ions through L-type calcium channels in vascular smooth muscle and cardiac muscle, leading to vasodilation and reduced myocardial contractility.
Initial: 30 mg orally twice daily (SR capsules). Titrate up to 60 mg twice daily. Usual maintenance: 30-60 mg twice daily.
Initial dose: 10 mg orally 3 times daily; maintenance: 10-30 mg 3-4 times daily; maximum 180 mg/day. Extended-release (XL): 30-60 mg once daily; titrate up to 120 mg/day.
