Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bacteriostatic; binds reversibly to 30S ribosomal subunit, inhibits protein synthesis by blocking aminoacyl-tRNA binding to mRNA-ribosome complex.
Tetracycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing the attachment of aminoacyl-tRNA to the mRNA-ribosome complex.
250-500 mg orally every 6 hours
500 mg orally once daily for 28 days; for severe infections, 500 mg twice daily for 14 days.

Terminal elimination half-life is 6-12 hours in patients with normal renal function; prolonged in renal impairment (up to 48-72 hours in anuria).
6-11 hours (prolonged in renal impairment; up to 57 hours in anuria).
Renal (60% unchanged in urine via glomerular filtration), biliary/fecal (40% as active drug and metabolites, with a portion undergoing enterohepatic recirculation).
Renal 60% (glomerular filtration), fecal 40% (biliary excretion of active drug and metabolites).
