VASCOR vs VERILOID
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
VERILOID is a synthetic alkaloid that acts as a ganglionic blocker, inhibiting nicotinic acetylcholine receptors at autonomic ganglia, leading to reduced sympathetic and parasympathetic outflow. This results in vasodilation and decreased peripheral vascular resistance, lowering blood pressure.
Bepridil hydrochloride (Vascor) is typically dosed as 200 mg to 400 mg orally once daily.
Intravenous: 0.1-0.5 mg/kg bolus, followed by 0.5-2 mcg/kg/min continuous infusion. Oral: 20-80 mg every 6-8 hours.

Terminal elimination half-life: 6-8 hours (normal renal/hepatic function). May be prolonged in hepatic impairment; unchanged in renal impairment.
Terminal elimination half-life is 3-5 hours, clinically relevant for dose scheduling to maintain steady-state levels.
Primarily hepatic metabolism; ~70% excreted in feces as metabolites, ~30% in urine (largely as metabolites). <2% excreted unchanged in urine.
Renal excretion accounts for approximately 60% as unchanged drug; hepatic metabolism contributes 30% with biliary-fecal elimination of metabolites, totaling ~10% fecal.
