Terminal elimination half-life is 12-15 hours in healthy adults; prolonged to 20-30 hours in severe hepatic impairment and 15-20 hours in renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is 8–12 hours in healthy adults; prolonged to 20–30 hours in severe renal impairment (CrCl <30 mL/min), requiring dose adjustment.
Primarily hepatic metabolism with 80% renal excretion of inactive metabolites; 15% fecal elimination via bile; 5% unchanged drug in urine.
Primarily renal excretion (approximately 70% as unchanged drug via glomerular filtration and tubular secretion); biliary/fecal elimination accounts for about 20% (including metabolites); 10% undergoes metabolic clearance.
