CLEVIPREX vs SULAR
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.
Nisoldipine is a dihydropyridine calcium channel blocker that inhibits the influx of calcium ions through L-type calcium channels in vascular smooth muscle and cardiac muscle. This leads to vasodilation, reduced peripheral vascular resistance, and decreased myocardial oxygen demand.
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.
10-20 mg orally once daily; maximum 60 mg/day.

Terminal elimination half-life: 2.7 minutes (dihydropyridine ring reduction) and 15 minutes (ester hydrolysis); clinical context: rapid offset allows precise titration
Terminal half-life of 24-50 hours, mean ~34 hours; extended in elderly and hepatic impairment, dose adjustment may be needed
Renal: 63–73% as metabolites, fecal: 7–10%, unchanged drug in urine: <1%
Renal: 50-60% as metabolites, 10% as unchanged drug; Fecal: ~35%; Biliary: <5%
