 Use of Sulfamethazine


Sulfamethazine is a sulfonamide antibacterial.Target: AntibacterialSulfamethazine is an antibiotic used to treat bronchitis, prostatitis and urinary tract infections. Sulfamethazine blocks the synthesis of dihydrofolic acid by inhibiting dihydropteroate synthase. In addition, sulfamethazine is a structural analog and competitive antagonist of para-aminobenzoic acid (PABA) and can inhibit normal bacterial utilization of PABA for the synthesis of folic acid, which is an important metabolite in DNA synthesis [1, 2].
