Pyrimethamin e is a widely used broad-spectrum antiprotozoal veterinary medicine. In addition to this, pyrimethamin e can also be applied to the breeding of the aquatic product and is also capable of enhancing the disease resistance capability of aquaculture fish. However, pyrimethamin e has significant side effects with being used in excess amount being able to cause damage to the reproductive system of livestock and poultry, and is also difficult for recovery. Pyrimethamin e has inhibitory effect on the primary exo-erythrocytic stage of Plasmodium falciparum and vivax malaria, and is a good preventive medicine. Although it has no significant effects on the malaria gametocyte but when the drug-containing blood enters into the mosquito body, it can affect the development of gametocytes inside mosquitoes, thus being able to interrupt the transmission. The mechanism of action is to inhibit the dihydrofolate reductase and affect the utilization of folate, causing reduction of the nucleic acid synthesis and inhibiting the malaria parasite reproduction. Meanwhile pyrimethamin e and chloroquin e, through lowering the level of oxidative stress and apoptosis, can exert protective effect on the placental pathology after the infection of malaria and can also reduce the proportion of infected red cells in the blood, therefore being able to achieving a excellent therapeutic effect on malaria. It also has enrichment effect in aquatic body. Upon going beyond a certain range, it can cause hemolytic anemia after being eaten and even has direct toxicity on the central nervous system.

It has inhibitory effects on the primary exo-erythrocytic stage of some kinds of Plasmodium falciparum and vivax malaria and is a good preventive medicine. Owing to its slow excretion rate, it has a long-lasting effect with the preventive effect of one-time medication being able to be maintained for more than 1 week. Although this product has no significant effects on the malaria gametocyte but when the drug-containing blood is inhaled into the mosquito body, it can affect the development of gametocytes inside mosquitoes, thus being able to interrupt the transmission. Because of its effect on inhibiting the exo-erythrocytic stage of Plasmodium, it is usually used in combination with primaquin e for the prevention of recurrence.
