Sulfacetamide is an anti-infective agent from the sulfonamide drug class (antibiotic). This drug can be used topically to treat skin infections (acne vulgaris), as well as orally to treat urinary tract infections. It is also indicated in the treatment of bacterial vaginitis, keratitis, acute conjunctivitis, and blepharitis. Sulfacetamide is a bacteriostatic drug, it stops the replication of the bacteria. This molecule binds to the dihydropteroate synthase protein in a wide-spectrum activity against most gram-positive and many gram-negative organisms. The inhibited enzyme is essential for the synthesis of folic acid from para-aminobenzoic acid (PABA) molecules. Folic acids are essential for the growth of the bacteria.
