trimethoprimsulfa

Trimosulfa is a combination of trimethoprim and sulfamethoxazole, an antibiotic combination. Sulfamethoxazole inhibits dihydropteroate synthase, while trimethoprim inhibits dihydrofolate reductase (dihydrofolate reductase), making it effective for mild to moderate bacterial infections against many Gram-negative and Gram-positive bacteria.

Trimethoprim sulfate is a pyrimidine inhibitor of dihydrofolate reductase, it is an antibacterial related to PYRIMETHAMINE. The interference with folic acid metabolism may cause a depression of hematopoiesis. It is potentiated by SULFONAMIDES and the TRIMETHOPRIM-SULFAMETHOXAZOLE COMBINATION is the form most often used. It is sometimes used alone as an antimalarial. TRIMETHOPRIM RESISTANCE has been reported.
