BENZAMYCIN vs CENTANY
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Mupirocin binds to isoleucyl-tRNA synthetase, inhibiting bacterial protein synthesis.
Topical: Apply a thin layer to affected areas twice daily (morning and evening). Each gram contains 30 mg benzoyl peroxide and 30 mg erythromycin.
Apply a thin layer to affected area twice daily for 10 days. For perioral dermatitis, apply once daily.

2.5-3.5 hours in adults with normal renal function; may be prolonged to 4-6 hours in patients with hepatic impairment
8-10 minutes in serum; prolonged to 15-20 minutes in patients with renal impairment. Clinical context: Rapidly cleared, infrequent dosing intervals (e.g., every 20 minutes during procedure).
Renal excretion: ~70% (30% as unchanged drug, 40% as active metabolite N-desmethylclindamycin); biliary/fecal: ~30%
Primarily excreted unchanged in urine via glomerular filtration and tubular secretion (85-90% renal); minor biliary/fecal elimination (<5%).
