CLINDAMYCIN PHOSPHATE AND BENZOYL PEROXIDE vs LINCOMYCIN HCL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Clindamycin phosphate is a lincosamide antibiotic that inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, suppressing peptide bond formation. Benzoyl peroxide is an oxidizing agent with bactericidal activity against Propionibacterium acnes, and also has keratolytic and comedolytic effects.
Lincomycin inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, inhibiting peptide bond formation and translocation.
Apply a thin film to affected areas twice daily (morning and evening).
600 mg IM every 12-24 hours or 600 mg IV every 8-12 hours, up to 8 g/day for severe infections.

Terminal elimination half-life of clindamycin after topical application is approximately 2.4 hours. However, due to slow release from skin depot, effective half-life extends to 6–12 hours, supporting twice-daily dosing. Benzoyl peroxide has a very short half-life (<1 minute) on skin due to rapid decomposition; systemic half-life of benzoic acid is ~0.9 hours.
4-5 hours (prolonged in renal impairment, up to 10 hours in anuria; no significant change in hepatic disease).
Clindamycin phosphate is a prodrug that is hydrolyzed to clindamycin. After topical application, systemic absorption is minimal (approximately 10% of applied dose). The absorbed clindamycin is primarily excreted via the kidneys (10% unchanged, 3% as metabolites) and biliary/fecal routes (approximately 4%). Benzoyl peroxide is converted to benzoic acid, which is up to 87% excreted in urine as hippuric acid after conjugation with glycine. Overall, for the combination, renal excretion accounts for ~10%, biliary/fecal ~4%, remainder remains unabsorbed or metabolized locally.
Renal (approximately 40% unchanged in urine) and biliary/fecal (approximately 50% as active drug and metabolites).
