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: 12-15 hours in healthy adults; clinically relevant for once-daily dosing.
Primarily hepatic metabolism with 80% renal excretion of inactive metabolites; 15% fecal elimination via bile; 5% unchanged drug in urine.
Renal excretion of unchanged drug: 60-70%; fecal/biliary elimination: 20-30%; hepatic metabolism accounts for <10%.
