Pharmacology And Toxicology Of Artequick

The product is a drug to treat malaria, particularly drug-resistant falciparum malaria. It is well tolerated and has rapid action, high efficacy, low toxicity and offers a short course treatment. Using the product to treat falciparum malaria with 56-day follow-up, the results showed that the cure rate was >95%, the fever and parasite clearance time were 16-30 and 36-60 hours respectively.

The product also has a parasiticidal effect on plasmodium vivax in the intra erythrocytic stage. Artemisinin in Artequick tablets has a powerful and quick parasiticidal effect on those parasites in the intra erythrocytic stage. Moreover, its efficacy is much quicker than that of quinine, chloroquine and other non artemisinin antimalarial drugs.

It therefore relieves clinical symptoms much faster. This product has significant gametocidal effects on falciparum malaria thus interrupts the generation of gametocytes in bone marrow and reduces the transmission.

The resistance culture showed that the drug resistance to this product is hard to occur. Piperaquine is a 4-aminoquinoline compound. Studies of the pharmacodynamic and toxicological properties in rodent malaria showed that the efficacy and curative index of piperaquine were 2.6 and 66 times higher than those of chloroquine.

Since 1978, piperaquine has been used widely to replace chloroquine to treat malaria in China and proven its higher therapeutic efficacy and lower side effects than those of chloroquine The results of acute toxicity tests in mice given the drug by intragastric administration showed that LD⁵⁰ of the product was 1062 5 mg/kg, and the toxicity of the combination of the two components was not potentiated but additive. Genetic toxicology tests showed that the product has no mutagenic effects.
