Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Doxycycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, blocking the attachment of aminoacyl-tRNA to the mRNA-ribosome complex.
Tetracycline antibiotic; inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing aminoacyl-tRNA from binding to the mRNA-ribosome complex.
100 mg orally or IV every 12 hours on day 1, then 100 mg orally or IV every 24 hours; for severe infections, 100 mg every 12 hours.
100 mg orally twice daily on day 1, then 100 mg orally once daily

Terminal elimination half-life: 14-22 hours (mean ~18 hours) in adults; prolonged up to 24-48 hours in renal impairment; no dose adjustment in mild-moderate renal impairment but caution in severe (CrCl <30 mL/min).
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: ~40% (glomerular filtration, tubular secretion); biliary: ~20-60% (enterohepatic circulation); fecal: ~30% (unabsorbed or excreted in bile).
Renal (40% as unchanged drug via glomerular filtration), biliary/fecal (20-30%, including enterohepatic circulation).
