Pharmacological action :
sulfamethoxazole inhibits bacterial synthesis of dihydrofolic acid by competing with para aminobenzoic acid , trimethoprim blocks the production of tetrahydrofolic acid from dihydrofolic acid by binding to and reversibly inhibiting the required enzyme , dihydrofolate reductase . thus septazole blocks two consecutive steps in the biosynthesis of nucleic acids and proteins essential to many bacteria in vitro studies have shown that bacterial resistance develops more slowly with septazole than with either trimethoprim or sulfamethoxazole alone .
