ADALAT vs VASCOR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dihydropyridine calcium channel blocker; inhibits calcium ion influx across cardiac and vascular smooth muscle cells, reducing peripheral vascular resistance and blood pressure.
VASCOR (bepridil) is a calcium channel blocker that inhibits calcium ion influx across cardiac and smooth muscle cells, reducing contractility and oxygen demand. It also has class I and IV antiarrhythmic properties.
10-20 mg orally three times daily; extended-release: 30-60 mg orally once daily; maximum 120 mg/day.
Bepridil hydrochloride (Vascor) is typically dosed as 200 mg to 400 mg orally once daily.

Terminal elimination half-life: 2-5 hours (immediate-release); 8-14 hours (extended-release). Context: shorter half-life necessitates multiple daily dosing for immediate-release; extended-release allows once-daily dosing.
Terminal elimination half-life: 6-8 hours (normal renal/hepatic function). May be prolonged in hepatic impairment; unchanged in renal impairment.
Renal: 70-80% as metabolites; Fecal: 15-20% as metabolites; <1% unchanged in urine
Primarily hepatic metabolism; ~70% excreted in feces as metabolites, ~30% in urine (largely as metabolites). <2% excreted unchanged in urine.
