Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to the 30S ribosomal subunit, inhibiting protein synthesis by blocking aminoacyl-tRNA binding.
Tetracycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing the attachment of aminoacyl-tRNA to the A site.
250-500 mg orally every 6 hours; or 10-20 mg/kg/day intravenously divided every 12 hours
250–500 mg orally every 6 hours; or 500 mg to 1 g intravenously every 6–12 hours (administer slow IV).

Terminal elimination half-life: 8–12 hours (prolonged in renal impairment; may extend to 20–30 hours in anuria)
Terminal elimination half-life: 6-8 hours in normal renal function; prolonged to 18-30 hours in severe renal impairment (CrCl <30 mL/min); dosing adjustment required.
Renal (70% unchanged), biliary/fecal (30% as metabolites and unchanged drug)
Renal (glomerular filtration): 60% unchanged in urine; biliary/fecal: 40% as active drug and metabolites; enterohepatic recirculation occurs.
