BRISTACYCLINE vs NUZYRA
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.
Omadacycline is a aminomethylcycline antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, blocking aminoacyl-tRNA binding to the A site.
250 mg orally every 6 hours for 7-14 days.
200 mg intravenously once on day 1, then 100 mg IV once daily; or 200 mg orally once on day 1, then 100 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 approximately 17-21 hours; supports once-daily dosing.
Renal (40-60% unchanged), fecal (20-30%, primarily as inactive metabolites). Biliary excretion contributes minimally (<5%).
Fecal (approximately 76%) as unchanged drug; renal (approximately 14%) as unchanged drug; biliary excretion is minimal.
