Terminal elimination half-life is 6-8 hours in patients with normal renal function. Half-life is significantly prolonged (up to 80 hours) in anuria, requiring dose adjustment.
Terminal elimination half-life: 8-10 hours in normal renal function; prolonged to 20-40 hours in severe renal impairment (creatinine clearance <10 mL/min).
Primarily renal excretion of unchanged drug via glomerular filtration; 80-90% recovered in urine within 24 hours. Biliary/fecal excretion accounts for <5%.
Renal (primarily glomerular filtration, 20-60% unchanged in urine), biliary/fecal (10-30% via bile into feces).
