Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Tetracycline antibiotic; inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing aminoacyl-tRNA binding 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.
100 mg orally or IV every 12 hours on day 1, then 100 mg daily.
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 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.
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).
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: ~40% (glomerular filtration, tubular secretion); biliary: ~20-60% (enterohepatic circulation); fecal: ~30% (unabsorbed or excreted in bile).
