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.
Verapamil inhibits calcium ion influx across cardiac and vascular smooth muscle cells, blocking L-type calcium channels, leading to vasodilation and reduced myocardial contractility and conduction velocity.
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.
Initial dose: 80-120 mg orally three times daily; sustained-release: 120-240 mg orally once daily. IV: 5-10 mg slow IV push over 2 minutes, may repeat after 15-30 minutes. Maximum daily oral dose: 480 mg.

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: 4.5-12 hours (mean 8 hours); increases with hepatic impairment or cirrhosis
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%.
Renal (70% as metabolites, 3-5% unchanged); biliary/fecal (25%)
