Description

Benzoyl Peroxide 5% + Erythromycin 3% Topical is a dual-action medicine used for acne vulgaris. Benzoyl Peroxide has mild keratolytic effect and antimicrobial activity attributed to its oxidative property. It is active against S.epidermidis and P.acne. Erythromycin inhibits protein synthesis by irreversibly binding to the 50S ribosomal subunit, blocking transpeptidation or translocation reactions, resulting in stunted cell growth. Apply topically to affected areas after thoroughly washing and drying the skin.
