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.
Clindamycin phosphate is a prodrug that is hydrolyzed to clindamycin, which reversibly binds to the 50S subunit of the bacterial ribosome, inhibiting protein synthesis by blocking peptide bond formation. It exhibits primarily bacteriostatic activity against susceptible gram-positive cocci and anaerobes.
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).
Clindamycin 600-2700 mg/day IV divided every 6-8 hours. For severe infections, up to 4800 mg/day IV may be given.

Clindamycin terminal elimination half-life is 2-4 hours in adults; benzoyl peroxide has minimal systemic absorption, so half-life is not clinically relevant.
The terminal elimination half-life is approximately 2.4-3.0 hours in adults with normal renal and hepatic function; prolonged to 3-6 hours in hepatic impairment and up to 8-14 hours in severe 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.
Clindamycin is primarily eliminated via hepatic metabolism; approximately 10% is excreted unchanged in urine, 3.6% in feces, and the remainder as inactive metabolites in bile and urine.
