DEMECLOCYCLINE HYDROCHLORIDE vs VIBRAMYCIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to the 30S ribosomal subunit, inhibiting protein synthesis by preventing aminoacyl-tRNA from attaching to the mRNA-ribosome complex.
Inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing addition of amino acids to the growing peptide chain. Bacteriostatic.
150 mg orally every 6 hours or 300 mg orally every 12 hours. Maximum daily dose: 1200 mg.
100 mg orally or intravenously every 12 hours on day 1, then 100 mg once daily; severe infections: 100 mg every 12 hours.

10-17 hours; prolonged in renal impairment (up to 40–50 hours)
Terminal elimination half-life is 16-18 hours in patients with normal renal function. Prolonged to 20-36 hours in severe renal impairment; no significant change in hepatic impairment.
Renal: 40-50% unchanged; fecal/biliary: 10-15%
Approximately 40% excreted unchanged in urine via glomerular filtration; 20-25% eliminated in feces via biliary secretion; remainder metabolized. Renal clearance is about 30 mL/min.
