摘要:

本文对阿齐沙坦微粉化工艺中的降解产物以及对降解过程的控制进行了研究。通过HPLC检测发现, 原料药在微粉化过程中产生两个杂质DP-1DP-2, 其中DP-2尚未见文献报道。经核磁共振谱和质谱对两个杂质的结构进行了鉴定,同时可以通过改变微粉化工艺对两个杂质的产生进行控制。

Abstract:

The degradation of Azilsartan in the micronization process was studied and a degradation control method was developed. In the micronization process of Azilsartan, two degradation products (DP-1 and DP-2) were detected by HPLC. DP-1 is a known impurity but DP-2 has not been reported before. The structures of the two degradation products were identified by NMR and MS analysis. The formation of DP-1 and DP-2 can be controlled by changing the micronization process.

Key words: Azilsartan, Degradation, Impurities, Micronization
