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 causes vasodilation and decreases systemic vascular resistance.
Cardizem LA (diltiazem) is a calcium channel blocker that inhibits calcium ion influx across cardiac and smooth muscle cells during depolarization, leading to negative inotropic, chronotropic, and dromotropic effects. It dilates coronary and peripheral arteries, reducing systemic vascular resistance and myocardial oxygen demand.
Intravenous infusion: initial dose 5 mg/hour, titrate by 2.5-5 mg/hour every 15-30 minutes as needed; maximum 15 mg/hour. Oral: 20 mg three times daily initially, then 30-40 mg three times daily.
Oral, 180-360 mg once daily; initiate at 180 mg once daily, titrate to 240 mg, then 300 mg, then 360 mg once daily as needed.

2 to 4 hours in healthy subjects; increased in hepatic impairment (up to 7 hours) and in elderly. No significant change in renal impairment.
Terminal elimination half-life: 5-8 hours after oral administration. For extended-release formulations, the half-life is similar but the prolonged absorption phase results in sustained plasma concentrations.
Primarily hepatic metabolism to inactive metabolites; <1% excreted unchanged in urine. Biliary/fecal excretion of metabolites accounts for approximately 60-70% of total elimination, with renal excretion of metabolites approximately 30-40%.
Urine (2-4% unchanged, ~40% as metabolites); bile/feces (major route, ~60% as metabolites).
