Bar of this enzyme prevents the organization of the metabolically sprightly fabric of folic acid, tetrahydrofolic acid, and thus, interferes with general bacterial apartment functions. Trimethoprim binds to bacterial dihydrofolate reductase more swiftly than it does to individual dihydrofolate reductase, which accounts looking for the demanding toxicity of the medicament. Antibacterial spectrumThe antibacterial spectrum of trimethoprim is nearly the same to that of sulfamethoxazole. Rebelliousness Resistance in gram-negative bacteria is due to the presence of an altered dihydrofolate reductase that has a deign friendliness as a service to trimethoprim. Because the cure-all is a weak-minded base, higher concentrations of trimethoprim are achieved in the extent acidic prostatic and vaginal fluids. The drug is widely distributed into main part tissues and fluids, including entrance into the cerebrospinal unsettled.
