BACI-RX vs BENZAMYCIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bacitracin inhibits bacterial cell wall synthesis by interfering with the dephosphorylation of the lipid carrier that transports peptidoglycan precursors, thereby blocking cell wall formation.
BENZAMYCIN (benzoyl peroxide and clindamycin) combines the keratolytic and antimicrobial actions of benzoyl peroxide with the antibacterial effect of clindamycin, a lincosamide antibiotic that inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit.
1-2 units/kg intramuscularly every 2-4 hours as needed for hemophilia A; intravenous infusion 40-50 units/kg for major surgery or life-threatening bleeding, then 20-25 units/kg every 8 hours.
Topical: Apply a thin layer to affected areas twice daily (morning and evening). Each gram contains 30 mg benzoyl peroxide and 30 mg erythromycin.

Terminal half-life: 2-3 hours in patients with normal renal function; prolonged to 20-40 hours in anuria. Clinical context: Dosing interval adjustment required for creatinine clearance <30 mL/min.
2.5-3.5 hours in adults with normal renal function; may be prolonged to 4-6 hours in patients with hepatic impairment
Renal: 90-100% as unchanged drug via glomerular filtration; biliary/fecal: negligible.
Renal excretion: ~70% (30% as unchanged drug, 40% as active metabolite N-desmethylclindamycin); biliary/fecal: ~30%
