AFEDITAB CR vs CLEVIPREX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nifedipine is a dihydropyridine calcium channel blocker that inhibits the influx of calcium ions through L-type channels in vascular smooth muscle and cardiac muscle, leading to vasodilation and reduced myocardial contractility.
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.
30-60 mg orally once daily, extended-release; maximum 90 mg/day.
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.

Terminal elimination half-life is 6-11 hours; prolonged in hepatic impairment and elderly due to reduced clearance
Terminal elimination half-life: 2.7 minutes (dihydropyridine ring reduction) and 15 minutes (ester hydrolysis); clinical context: rapid offset allows precise titration
Renal (80% as inactive metabolites), fecal (15% as metabolites), unchanged drug (<1%)
Renal: 63–73% as metabolites, fecal: 7–10%, unchanged drug in urine: <1%
