MINOCIN vs VIBRAMYCIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Minocycline is a tetracycline antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, blocking the binding of aminoacyl-tRNA 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.
100 mg orally or intravenously every 12 hours for 24 hours, then 100 mg every 12 hours; severe infections: 200 mg initially, then 100 mg every 12 hours.
100 mg orally or intravenously every 12 hours on day 1, then 100 mg once daily; severe infections: 100 mg every 12 hours.

Terminal elimination half-life is 11–17 hours in patients with normal renal function; prolonged up to 18–69 hours in renal impairment.
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.
Primarily renal (approximately 70% unchanged) and biliary/fecal (approximately 30%, with enterohepatic recycling).
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.
