Terminal elimination half-life is 6-8 hours; in moderate renal impairment (CrCl 30-50 mL/min) extends to 12-15 hours.
2-3 hours (terminal); prolonged in hepatic impairment; circadian-timed formulation intended for once-daily morning dosing.
Primarily renal excretion (70-80% as unchanged drug), with 15-20% fecal elimination via biliary secretion.
Renal: ~80% as inactive metabolites; fecal: ~5%; biliary: small amount.
