CARDENE vs KATERZIA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cardene (nicardipine) is a dihydropyridine calcium channel blocker that inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle. It dilates peripheral arterioles, reducing systemic vascular resistance and blood pressure, and also has coronary vasodilatory effects.
KATERZIA (bosentan) is an endothelin receptor antagonist (ERA) that blocks endothelin-1 (ET-1) from binding to ETA and ETB receptors in the endothelium and vascular smooth muscle. This inhibits ET-1-mediated vasoconstriction and smooth muscle proliferation, reducing pulmonary vascular resistance and pulmonary arterial pressure.
20-40 mg orally three times daily.
5 mg orally once daily for 21 days, then 7 days off, repeated in 28-day cycles.

1.5-2 hours (terminal); prolonged in hepatic impairment (up to 6-8 hours)
Terminal elimination half-life is approximately 9-12 hours in healthy adults. In patients with hypertension or hepatic impairment, half-life may be prolonged up to 15-20 hours, necessitating dose adjustment.
Renal: 60% as metabolites, 10% unchanged; Fecal: 35%
Renal elimination accounts for approximately 60-80% of the administered dose, predominantly as unchanged drug via glomerular filtration and active tubular secretion. Biliary/fecal excretion is minimal, <5%.
