Sulfacetamide is a sulfonamide antibiotic. Sulfonamides are synthetic bacteriostatic antibiotics, that are active against gram-positive and gram-negative bacteria. It blocks the synthesis of dihydrofolic acid by inhibiting the enzyme dihydropteroate synthase. It is a competitive inhibitor of bacterial para-aminobenzoic acid (PABA).PABA is required for bacterial synthesis of folic acid and it is an essential component for bacterial growth. The multiplication of bacteria is therefore inhibited by the action of sulfacetamide.
