Terminal half-life: 8-12 hours (average 10 hours); prolonged in hepatic impairment (up to 24 h) and severe renal impairment (up to 18 h).
Terminal elimination half-life is approximately 8-11 hours in healthy adults; prolonged in renal impairment (up to 20-30 hours in moderate to severe impairment).
Renal: 30-50% unchanged; hepatic metabolism: 50-70% (CYP3A4); biliary/fecal: 10-20%.
Primarily renal (approximately 70% as unchanged drug via glomerular filtration and tubular secretion); minor biliary/fecal elimination (<10%).
