Abstract

The invention discloses an artemether injection and a preparation method thereof. Each 1000mL injection contains 80-100g artemether, 20-30g benzyl alcohol, 100-150g ethyl oleate, 5-10g phospholipid, 50 ‑100mg antioxidant, the balance is soybean oil for injection. The artemether injection prepared by the invention not only has high active ingredient content, but also has excellent stability.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to an artemether injection and a preparation method thereof. Background technique [0002] Artemether is a derivative of artemisinin, which has a strong and rapid killing effect on the erythrocytic apomict of Plasmodium. To control the clinical onset and symptoms, it is used for the treatment of chloroquine-resistant falciparum malaria and dangerous malaria, and the effect is rapid and the curative effect is good. Animal experiments have shown that its antimalarial effect is 10 to 20 times that of artemisinin. [0003] The existing artemether injection is prepared by heating and miscible with artemether as the active ingredient, benzyl alcohol and soybean oil as the solvent. However, the artemether injection prepared by the above process has the disadvantages of poor stability and low artemether content, and it is difficult to meet the requirements of quality c...
