BRISTACYCLINE vs MONODOX
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.
Doxycycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, blocking the attachment of aminoacyl-tRNA to the mRNA-ribosome complex.
250 mg orally every 6 hours for 7-14 days.
100 mg orally or IV every 12 hours on day 1, then 100 mg orally or IV every 24 hours; for severe infections, 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: 14-22 hours (mean ~18 hours) in adults; prolonged up to 24-48 hours in renal impairment; no dose adjustment in mild-moderate renal impairment but caution in severe (CrCl <30 mL/min).
Renal (40-60% unchanged), fecal (20-30%, primarily as inactive metabolites). Biliary excretion contributes minimally (<5%).
Renal: ~40% (glomerular filtration, tubular secretion); biliary: ~20-60% (enterohepatic circulation); fecal: ~30% (unabsorbed or excreted in bile).
