BRISTACYCLINE vs RONDOMYCIN
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.
Binds to the 30S ribosomal subunit, inhibiting protein synthesis by blocking the attachment of aminoacyl-tRNA to the mRNA-ribosome complex.
250 mg orally every 6 hours for 7-14 days.
150 mg orally twice daily or 300 mg orally once daily.

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 6-8 hours in patients with normal renal function; may extend to 20-30 hours in severe renal impairment.
Renal (40-60% unchanged), fecal (20-30%, primarily as inactive metabolites). Biliary excretion contributes minimally (<5%).
Renal (40-50% unchanged), biliary/fecal (10-20% as metabolites and unchanged drug). Approximately 30% undergoes enterohepatic circulation.
