CARDENE vs ISRADIPINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cardene (nicardipine) is a dihydropyridine calcium channel blocker that inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle. It dilates peripheral arterioles, reducing systemic vascular resistance and blood pressure, and also has coronary vasodilatory effects.
Isradipine is a dihydropyridine calcium channel blocker that inhibits the influx of extracellular calcium ions into vascular smooth muscle and myocardial cells via L-type calcium channels, leading to vasodilation and reduced peripheral vascular resistance, with minimal negative inotropic effect.
20-40 mg orally three times daily.
2.5-10 mg orally twice daily. Initial dose: 2.5 mg twice daily, titrate to 5-10 mg twice daily as needed.

1.5-2 hours (terminal); prolonged in hepatic impairment (up to 6-8 hours)
Terminal elimination half-life 8 hours (range 6-12 hours); clinical context: supports twice-daily dosing, requires dose adjustment in hepatic impairment.
Renal: 60% as metabolites, 10% unchanged; Fecal: 35%
Renal: 65% (as metabolites, <1% unchanged); Fecal: 35% (biliary elimination); total clearance 1.4 L/min.
