BENZOYL PEROXIDE AND CLINDAMYCIN PHOSPHATE vs LINCOMYCIN HCL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benzoyl peroxide: oxidizes bacterial proteins via free radical release, reducing Cutibacterium acnes; keratolytic and comedolytic. Clindamycin phosphate: inhibits bacterial protein synthesis by binding to 50S ribosomal subunit, bacteriostatic against C. acnes.
Lincomycin inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, inhibiting peptide bond formation and translocation.
Topical: Apply a thin film to affected areas twice daily (morning and evening). Each gram of gel contains 50 mg benzoyl peroxide and 10 mg clindamycin phosphate (as clindamycin).
600 mg IM every 12-24 hours or 600 mg IV every 8-12 hours, up to 8 g/day for severe infections.

Clindamycin terminal elimination half-life is 2-4 hours in adults; benzoyl peroxide has minimal systemic absorption, so half-life is not clinically relevant.
4-5 hours (prolonged in renal impairment, up to 10 hours in anuria; no significant change in hepatic disease).
Benzoyl peroxide is metabolized to benzoic acid, which is excreted in urine as hippuric acid; clindamycin phosphate is hydrolyzed to clindamycin, which undergoes hepatic metabolism with about 10% excreted unchanged in urine, 3.6% in feces as active drug, and the remainder as metabolites.
Renal (approximately 40% unchanged in urine) and biliary/fecal (approximately 50% as active drug and metabolites).
