CLEVIPREX vs VERELAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cleviprex (clevidipine) is a dihydropyridine L-type calcium channel blocker with high vascular selectivity. It inhibits calcium influx into vascular smooth muscle cells, causing arterial vasodilation and reduced peripheral 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.
Initiate intravenous infusion at 1-2 mg/kg/hr, titrate by 0.5-1 mg/kg/hr every 90 minutes up to maximum 32 mg/kg/hr. Maintenance dose: 4-6 mg/kg/hr. Route: IV. Frequency: continuous infusion.
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.

Terminal elimination half-life: 2.7 minutes (dihydropyridine ring reduction) and 15 minutes (ester hydrolysis); clinical context: rapid offset allows precise titration
Terminal elimination half-life is 2.8 to 7.4 hours in healthy adults, prolonged in hepatic impairment or elderly (up to 12 hours).
Renal: 63–73% as metabolites, fecal: 7–10%, unchanged drug in urine: <1%
Renal excretion accounts for approximately 70% of elimination, with 3-4% as unchanged drug. Fecal elimination accounts for about 25%, predominantly via biliary secretion.
