Description
Sources: https://www.drugbank.ca/drugs/DB01582
Curator's Comment: Description was created based on several sources, including https://www.fda.gov/downloads/AnimalVeterinary/Products/ApprovedAnimalDrugProducts/FOIADrugSummaries/ucm061367.pdf | https://www.drugs.com/vet/sulfamethazine-25-solution-can.html

Sulfamethazine is a sulfonamide used to treat a variety of bacterial diseases in animals. It inhibits bacterial synthesis of dihydrofolic acid by competing with para-aminobenzoic acid (PABA) for binding to dihydropteroate synthetase (dihydrofolate synthetase).
