Terminal elimination half-life is 50 hours (range 30-86 hours), allowing once-daily dosing. Prolonged in elderly (up to 80 hours) and in hepatic impairment.
Renal: 50-60% as metabolites and conjugates; biliary/fecal: ~5%; remainder uncharacterized.
Approximately 60-70% renal (glomerular filtration and tubular secretion) as unchanged drug and metabolites; 30-40% fecal via biliary excretion. Less than 5% as unchanged drug in urine.
