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: 21-28 hours; clinical context: permits once-daily dosing
Primarily hepatic metabolism with 80% renal excretion of inactive metabolites; 15% fecal elimination via bile; 5% unchanged drug in urine.
Renal: ~50% (30% as unchanged drug, 20% as metabolites); Fecal: ~40%; Biliary: minor
