Terminal elimination half-life is 18–22 hours in patients with normal renal function; prolonged to 20–30 hours in severe renal impairment. Clinical context: Allows once- or twice-daily dosing.
6-12 hours; prolonged in renal impairment (up to 24-48 hours in anuria)
Doxycycline hyclate is primarily excreted via the feces (approximately 90%) as an inactive chelated complex, with renal excretion accounting for about 10% of the dose. Biliary excretion is minimal.
Renal (60-80% unchanged via glomerular filtration), biliary/fecal (20-40%)
