ACANYA vs BENZAMYCIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Acanya is a combination of clindamycin, a lincosamide antibiotic that inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, and benzoyl peroxide, an oxidizing agent with bactericidal and keratolytic activity. Benzoyl peroxide exerts its effect by releasing free radical oxygen that oxidizes bacterial proteins and has been shown to reduce Propionibacterium acnes.
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.
Apply a pea-sized amount to the entire face once daily in the evening, topical.
Topical: Apply a thin layer to affected areas twice daily (morning and evening). Each gram contains 30 mg benzoyl peroxide and 30 mg erythromycin.

Clindamycin: after topical application, terminal half-life is approximately 2-3 hours in serum, but clinical relevance is minimal due to low systemic levels. Benzoyl peroxide metabolites have a half-life of ~1-2 hours. The clinical effect is primarily local with sustained antimicrobial and keratolytic activity.
2.5-3.5 hours in adults with normal renal function; may be prolonged to 4-6 hours in patients with hepatic impairment
Acanya (clindamycin phosphate 1.2% and benzoyl peroxide 2.5% gel) is a fixed-dose combination applied topically. Systemic absorption is minimal. Clindamycin: <0.1% of applied dose excreted renally as parent and metabolites. Benzoyl peroxide: metabolized to benzoic acid, which is conjugated and excreted renally; <5% of applied dose appears in urine. Fecal excretion is negligible.
Renal excretion: ~70% (30% as unchanged drug, 40% as active metabolite N-desmethylclindamycin); biliary/fecal: ~30%
