It acts on dihydrofolate synthase, interfering with the first step of folic acid synthesis. When used in combination with trimethoprim, it can doubly block the bacterial folic acid metabolism, enhance the synergistic antibacterial effect, and reduce drug-resistant strains.

It acts on the second step of folic acid anabolism and selectively inhibits the action of dihydrofolate reductase. When used in combination with sulfamethoxazole, it can double-block the bacterial folic acid metabolism, enhance the synergistic antibacterial effect, and reduce drug-resistant strains.

This product is a broad-spectrum antibiotic, the mechanism of action is to inhibit bacterial protein synthesis, and is effective against most Gram-negative and some Gram-positive bacteria, as well as Chlamydia trachomatis and Rickettsia.

Regulate autonomic dysfunction and endocrine imbalance

It can inhibit viral DNA and RNA polymerase, thereby inhibiting viral reproduction. On human embryonic kidney cells, 1% concentration has a significant inhibitory effect on DNA viruses (adenovirus, herpes virus) and RNA viruses (echovirus), and has an inhibitory effect on all stages of the viral proliferation cycle. It has no direct effect on free viral particles.

It participates in amino acid metabolism, synthesis of neurotransmitters, synthesis of collagen and tissue cell interstitial, can reduce the permeability of capillaries, accelerate blood coagulation, stimulate coagulation function, promote iron absorption in the intestine, promote the decrease of blood lipids, increase resistance to infection, participate in detoxification function, and has antihistamine effect and prevents the formation of carcinogens (nitrosamines).
