BRISTACYCLINE vs MINOCIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
BRISTACYCLINE is a tetracycline antibiotic that reversibly binds to the 30S ribosomal subunit, inhibiting bacterial protein synthesis by blocking the attachment of aminoacyl-tRNA to the mRNA-ribosome complex.
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.
250 mg orally every 6 hours for 7-14 days.
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.

6-12 hours (terminal). In renal impairment, half-life extends up to 24-48 hours; dose adjustment required for CrCl <30 mL/min.
Terminal elimination half-life is 11–17 hours in patients with normal renal function; prolonged up to 18–69 hours in renal impairment.
Renal (40-60% unchanged), fecal (20-30%, primarily as inactive metabolites). Biliary excretion contributes minimally (<5%).
Primarily renal (approximately 70% unchanged) and biliary/fecal (approximately 30%, with enterohepatic recycling).
