CLEVIPREX vs NIMOTOP
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.
Nimodipine is a dihydropyridine calcium channel blocker that selectively inhibits calcium influx into vascular smooth muscle cells, leading to vasodilation. It has a preferential effect on cerebral arteries, reducing the incidence of vasospasm following subarachnoid hemorrhage.
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.
60 mg orally every 4 hours for 21 days, initiated within 96 hours of subarachnoid hemorrhage. If unable to swallow, 0.5 mg/h continuous IV infusion via central line; increase to 1 mg/h after 2 hours if tolerated, continue for up to 21 days.

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 approximately 8–9 hours (range 3–12 hours) in adults, with clinical context of twice-daily dosing for continuous cerebral vasodilation in subarachnoid hemorrhage.
Renal: 63–73% as metabolites, fecal: 7–10%, unchanged drug in urine: <1%
Primarily hepatic metabolism; 50% excreted in urine as metabolites, 30% in feces via biliary elimination. Less than 1% excreted unchanged in urine.
