Doxycycline is a tetracycline antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing aminoacyl-tRNA from binding to the mRNA-ribosome complex.

Terminal elimination half-life: 18-22 hours (mean ~20 hours) in adults with normal renal function. Clinically, this supports twice-daily dosing; prolonged in severe renal impairment (up to 40-60 hours) or hepatic impairment.
Terminal elimination half-life: 18-22 hours (single dose); increases to 24-48 hours in renal impairment. Mean half-life after multiple doses: 14-16 hours.
Renal (approx. 40% as unchanged drug via glomerular filtration), biliary/fecal (approx. 60% as active and inactive metabolites, with significant enterohepatic recycling). Dose adjustment not required in mild renal impairment, but caution in severe hepatic dysfunction.
Renal (40% as unchanged drug via glomerular filtration), biliary/fecal (20-30%, including enterohepatic circulation).
