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, preventing tRNA-amino acid binding. It also exhibits anti-inflammatory effects by inhibiting matrix metalloproteinases and downregulating cytokine production.
Oxytetracycline binds reversibly to the 30S ribosomal subunit, inhibiting protein synthesis by blocking the attachment of aminoacyl-tRNA to the mRNA-ribosome complex.
40 mg orally once daily in the morning, on an empty stomach, at least 1 hour before or 2 hours after meals.
250-500 mg orally every 6 hours or 1-2 g/day divided every 12 hours intravenously.

Terminal elimination half-life is 18–22 hours in patients with normal renal function; prolonged in renal impairment (up to 44 hours in severe dysfunction), necessitating dose adjustment for CrCl <30 mL/min.
6-10 hours (prolonged to 48-100 hours in renal impairment; consider dose adjustment in CrCl <50 mL/min)
Primarily renal, with about 60% of a dose excreted unchanged in urine via glomerular filtration; biliary/fecal excretion accounts for approximately 35% as active drug and conjugates.
Renal (60-70% unchanged by glomerular filtration); biliary/fecal (20-35%)
