Terminal elimination half-life is 8-12 hours in adults with normal renal function; prolonged to 18-24 hours in moderate renal impairment (CrCl 30-50 mL/min).
Terminal elimination half-life is 8-12 hours in adults with normal renal function, allowing twice-daily dosing.
Renal excretion of unchanged drug accounts for 60-70% of elimination; biliary/fecal excretion accounts for 20-30%; less than 10% metabolized hepatically.
Renal elimination of unchanged drug accounts for approximately 60-70% of the dose; biliary excretion contributes about 20-25%, with the remainder eliminated via feces.
