12–15 hours in adults with normal renal function; prolonged to 30–40 hours in severe renal impairment (CrCl <30 mL/min).

Renal: 80% as unchanged drug; biliary/fecal: 15% as metabolites; <5% unchanged in feces.
Approximately 84% of a dose is excreted renally as unchanged drug; 12% in feces via biliary elimination.
