Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bacteriostatic antibiotic that reversibly binds to the 30S ribosomal subunit, inhibiting protein synthesis by preventing attachment of aminoacyl-tRNA to the mRNA-ribosome complex.
Doxycycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, blocking the attachment of aminoacyl-tRNA to the mRNA-ribosome complex.
200 mg orally or intravenously once, followed by 100 mg every 12 hours; maximum 400 mg/day.
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.

Terminal elimination half-life: 11–17 hours (mean ~15 hours in normal renal function); prolonged to 18–30 hours in renal impairment; context: allows twice-daily dosing, but accumulation can occur in hepatic/renal dysfunction.
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).
Renal (approximately 10% unchanged; higher in impaired renal function), biliary/fecal (major route via feces as unchanged drug and metabolites, up to 70% overall elimination through hepatobiliary system).
Renal: ~40% (glomerular filtration, tubular secretion); biliary: ~20-60% (enterohepatic circulation); fecal: ~30% (unabsorbed or excreted in bile).
