Sulfisoxazole is only found in individuals that have used or taken this drug. It is a short-acting sulfonamide antibacterial with activity against a wide range of gram- negative and gram-positive organisms. [PubChem]Sulfisoxazole is a competitive inhibitor of the enzyme dihydropteroate synthetase. It inhibits bacterial synthesis of dihydrofolic acid by preventing the condensation of the pteridine with para-aminobenzoic acid (PABA), a substrate of the enzyme dihydropteroate synthetase. The inhibited reaction is necessary in these organisms for the synthesis of folic acid.
