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).
Terminal elimination half-life is 12-15 hours in healthy adults; prolonged in renal/hepatic impairment.
Primarily renal (approximately 70% as unchanged drug via glomerular filtration and tubular secretion); minor biliary/fecal elimination (<10%).
Renal excretion of metabolites (approx. 60%) and unchanged drug (<5%); biliary/fecal elimination accounts for about 40%.
