Pyrimethamine is a broad-spectrum veterinary drug widely used in antigenic worm.
The principle of action of pyrimethamine is to inhibit dihydrofolate reductase, affect the utilization of tetrahydrofolate, reduce nucleic acid synthesis, and inhibit the reproduction of malaria parasites. At the same time, pyrimethamine and chloroquine can reduce the level of oxidative stress and apoptosis, protect against placental pathological changes after infection with malaria, and also effectively reduce the proportion of infected red blood cells in the blood, so as to achieve a good malaria treatment effect.
