BENZACLIN vs FOAMCOAT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
BENZACLIN (clindamycin 1% and benzoyl peroxide 5%) is a combination antibacterial agent. Clindamycin is a lincosamide antibiotic that binds to the 50S ribosomal subunit of bacteria, inhibiting protein synthesis and reducing Propionibacterium acnes growth. Benzoyl peroxide has bactericidal and keratolytic properties; it releases free radical oxygen species that oxidize bacterial proteins, decreasing P. acnes, and also causes drying and peeling of the skin.
FOAMCOAT is a proprietary fibrin sealant containing human fibrinogen and thrombin. When applied topically, thrombin converts fibrinogen into fibrin monomers that polymerize into a stable clot. This forms a mechanical barrier and promotes hemostasis through the final step of the coagulation cascade.
Topical gel applied once or twice daily to affected areas. Each gram contains 1% clindamycin and 5% benzoyl peroxide.
FOAMCOAT is a topical hemostatic agent; standard adult dose is 1 to 2 mL applied directly to bleeding site, repeated as needed.

After topical application, plasma concentrations of clindamycin are negligible; the systemic half-life of clindamycin from absorbed fraction is approximately 2.5-3 hours in adults. However, due to minimal systemic absorption, the terminal half-life is not clinically relevant for topical therapy.
Terminal elimination half-life is 3-4 hours in patients with normal renal function; may be prolonged in renal impairment.
Benzaclin (clindamycin 1% - benzoyl peroxide 5%) is a topical formulation; systemic absorption is minimal. After topical application, less than 1% of clindamycin is absorbed. Absorbed clindamycin is primarily excreted in urine (10% as active drug, 90% as metabolites) and feces (<5%). Benzoyl peroxide is metabolized to benzoic acid, which is conjugated and excreted in urine. Overall, renal excretion accounts for the majority of clearance of absorbed components.
Primarily renal excretion of intact drug (60-70%) with biliary/fecal elimination accounting for 20-30%.
