          Trimethoprim is a synthetic broad-spectrum antibacterial agent, which is used alone for respiratory infections, urinary tract infections, intestinal infections and other diseases, and can be used to treat sepsis, meningitis, otitis media, typhoid fever, shigellosis caused by sensitive bacteria ( Bacillary dysentery) etc.

          Trimethoprim is a bacterial dihydrofolate reductase inhibitor and a sulfonamide synergist. The principle of its antibacterial effect is to interfere with the folic acid metabolism of bacteria. It is mainly to selectively inhibit the activity of bacterial dihydrofolate reductase, so that dihydrofolate cannot be reduced to tetrahydrofolate, thereby inhibiting the growth and reproduction of bacteria. Trimethoprim has antibacterial activity against most Gram-positive bacteria and Gram-negative bacteria; in addition, trimethoprim also has a certain effect on Plasmodium and some fungi, such as Nocardia, Histoplasma, and yeast.

Applicable symptoms
