  Sulfa drug - Wikipedia, the free encyclopedia
Sulfa drugs are synthetic antimicrobial agents that contain the sulfonamide group.
In bacteria, sulfa drugs act as competitive inhibitors of para-Aminobenzoic acid (PABA), a substrate of the enzyme dihydropteroate synthetase.
Certain sulfonamides (sulfadiazine or sulfamethoxazole) are sometimes mixed with the drug trimethoprim, which acts against dihydrofolate reductase.
