Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Oxytetracycline binds reversibly to the 30S ribosomal subunit, inhibiting protein synthesis by blocking the attachment of aminoacyl-tRNA to the mRNA-ribosome complex.
Tetracycline inhibits protein synthesis by binding to the 30S ribosomal subunit, preventing aminoacyl-tRNA from binding to the ribosome.
250-500 mg orally every 6 hours or 1-2 g/day divided every 12 hours intravenously.

6-10 hours (prolonged to 48-100 hours in renal impairment; consider dose adjustment in CrCl <50 mL/min)
Terminal elimination half-life is 12–15 hours in adults with normal renal function; in renal impairment (CrCl <30 mL/min), half-life may extend to >30 hours, requiring dose adjustment.
Renal (60-70% unchanged by glomerular filtration); biliary/fecal (20-35%)
Renal excretion of unchanged drug accounts for approximately 60% of elimination; biliary/fecal excretion accounts for 30%; minor metabolic clearance accounts for 10%.
