Problems solved by technology

Among them, the main function of lactose as an excipient is to maintain the properties of the drug after freeze-drying, and has a certain stabilizing effect on the active ingredient fosaprepitant dimeglumine. In terms of maintaining the properties of the drug, the excipient commonly used in the freeze-drying process Agents mannitol, dextran, sorbitol and amino acids have similar effects, but the stability of the drug during storage cannot be guaranteed, especially the stability during long-term storage

Abstract

The invention particularly relates to a sterile freeze-dried fosaprepitant-dimeglumine powder for injection and a preparation process of the sterile freeze-dried fosaprepitant-dimeglumine powder. The sterile freeze-dried fosaprepitant-dimeglumine powder for injection comprises an active component, a solubilizing agent and a pH-value adjusting agent, wherein the active component is fosaprepitant dimeglumine. The preparation process of the sterile freeze-dried fosaprepitant-dimeglumine powder for injection is simple and feasible and is suitable for scale production. The sterile freeze-dried fosaprepitant-dimeglumine powder for injection has high quality and excellent stability and can be stored for a long time.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a sterile freeze-dried powder of fosaprepitant dimeglumine for injection and a preparation process thereof. Background technique [0002] Fosaprepitant Dimeglumine (Fosaprepitant Dimeglumine) is the prodrug of aprepitant (aprepitant), which is rapidly converted into aprepitant in the body after injection. This product, like aprepitant, belongs to the human substance P / neurokinin 1 (NK-1) selective high-affinity receptor blocker, which mainly acts by blocking the nausea and vomiting signals in the brain. In animal models, aprepitant inhibits emesis induced by cytotoxic chemotherapeutic drugs such as cisplatin through central nervous effects. Animal and human positron emission tomography (PET) studies have shown that aprepitant penetrates the blood-brain barrier and occupies the brain NK-1 receptor. Animal and clinical studies have shown that aprepitant increases the...
