Pharmacology: this product as artesunate derivatives of the parasite within a powerful and red of rapid exterminate action, can quickly control clinical attack and symptoms. The mechanism of action of artesunate was not very clear, mainly is the interference of the film a parasite table mitochondrial function. Artesunate through the influence of plasmodium falciparum within the ultrastructure of red, make its membrane structure are changing. Because of the membrane, the role of the food to humans through the bite of blocking the nutrition, when plasmodium falciparum, lose a lot of cytoplasm and nutrients, and can't get added, and will soon die. Its function way is by them peroxide (double oxygen) bridge, the hemoglobin decomposition is an iron mediated by free, produce unstable organic free radicals and/or other close electronic intermediary thing, and then the protein formation with plasmodium falciparum covalent add $thing, and make the malaria deaths. Artemether of antimalarial activity artesunate is six times greater. Toxicology: in the animal reproductive toxicity studies prove, mice induced phase to medicine, pregnancy can increase embryonic suck.
