BENZAMYCIN vs SODIUM SULAMYD
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
BENZAMYCIN (benzoyl peroxide and clindamycin) combines the keratolytic and antimicrobial actions of benzoyl peroxide with the antibacterial effect of clindamycin, a lincosamide antibiotic that inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit.
Sodium sulfacetamide is a sulfonamide antibiotic that inhibits bacterial dihydropteroate synthase, blocking folate synthesis.
Topical: Apply a thin layer to affected areas twice daily (morning and evening). Each gram contains 30 mg benzoyl peroxide and 30 mg erythromycin.
1-2 drops of 10% or 15% solution into affected eye(s) every 2-3 hours initially, tapered as infection resolves; ophthalmic ointment: apply 0.5-inch ribbon into conjunctival sac every 3-4 hours and at bedtime.

2.5-3.5 hours in adults with normal renal function; may be prolonged to 4-6 hours in patients with hepatic impairment
7-13 hours (prolonged in renal impairment; in anuria up to 22-50 hours)
Renal excretion: ~70% (30% as unchanged drug, 40% as active metabolite N-desmethylclindamycin); biliary/fecal: ~30%
Renal excretion of unchanged drug (approximately 70-100%) via glomerular filtration and tubular secretion; minor biliary/fecal elimination (<5%)
