Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nicardipine is a dihydropyridine calcium channel blocker that inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle. It causes vasodilation and decreases systemic vascular resistance.
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.
Intravenous infusion: initial dose 5 mg/hour, titrate by 2.5-5 mg/hour every 15-30 minutes as needed; maximum 15 mg/hour. Oral: 20 mg three times daily initially, then 30-40 mg three times daily.
5 mg orally once daily for 21 days, then 7 days off, repeated in 28-day cycles.

2 to 4 hours in healthy subjects; increased in hepatic impairment (up to 7 hours) and in elderly. No significant change in renal impairment.
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.
Primarily hepatic metabolism to inactive metabolites; <1% excreted unchanged in urine. Biliary/fecal excretion of metabolites accounts for approximately 60-70% of total elimination, with renal excretion of metabolites approximately 30-40%.
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%.
