SEPTAZOLE 400/80MG 20*10 TABS

Indication For the treatment bacterial infections causing bronchitis prostatitis and urinary tract infections. Mechanism of action Sulfonamides inhibit the enzymatic conversion of pteridine and p-aminobenzoic acid (PABA) to dihydropteroic acid by competing with PABA for binding to dihydrofolate synthetase an intermediate of tetrahydrofolic acid (THF) synthesis. THF is required for the synthesis of purines and dTMP and inhibition of its synthesis inhibits bacterial growth. Pyrimethamine and trimethoprim inhibit dihydrofolate reductase another step in THF synthesis and therefore act synergistically with the sulfonamides.
