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 smooth muscle cells, blocking L-type calcium channels, leading to vasodilation and negative chronotropic, dromotropic, and inotropic effects.
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.
Hypertension: 120-240 mg ER orally once daily; maximum 480 mg/day. Angina: 80-120 mg IR orally three times daily; ER 180-360 mg once daily.

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 is 2.8 to 7.4 hours in healthy adults, prolonged in hepatic impairment or elderly (up to 12 hours).
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 excretion accounts for approximately 70% of elimination, with 3-4% as unchanged drug. Fecal elimination accounts for about 25%, predominantly via biliary secretion.
