OXYTETRACYCLINE HYDROCHLORIDE vs TERRAMYCIN
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.
Inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing aminoacyl-tRNA from binding to the A site.
250-500 mg orally every 6 hours or 1-2 g/day divided every 12 hours intravenously.
250-500 mg orally every 6 hours or 1-2 g intravenously every 12 hours. Maximum oral dose: 2 g/day.

6-10 hours (prolonged to 48-100 hours in renal impairment; consider dose adjustment in CrCl <50 mL/min)
Terminal elimination half-life: 8-10 hours in normal renal function; prolonged to 20-40 hours in severe renal impairment (creatinine clearance <10 mL/min).
Renal (60-70% unchanged by glomerular filtration); biliary/fecal (20-35%)
Renal (primarily glomerular filtration, 20-60% unchanged in urine), biliary/fecal (10-30% via bile into feces).
