BENZOYL PEROXIDE AND CLINDAMYCIN PHOSPHATE vs LINCOMYCIN HYDROCHLORIDE
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.
Binds to the 50S subunit of the bacterial ribosome, inhibiting protein synthesis by blocking peptide bond formation.
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 intramuscularly every 24 hours or 600 mg intravenously every 8 to 12 hours. Maximum dose: 8 g/day intravenously.

Clindamycin terminal elimination half-life is 2-4 hours in adults; benzoyl peroxide has minimal systemic absorption, so half-life is not clinically relevant.
5.4 ± 1.0 hours (normal renal function); prolonged in hepatic impairment (up to 14 hours) and anuria (up to 10 hours)
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 (40% unchanged), biliary/fecal (significant via enterohepatic circulation; ~30% in feces)
