The present invention describes an amorphous form of trisodium salt of valsartan sacubitril complex and a process for the preparation of same comprising: reacting sacubitril sodium and valsartan disodium or sacubitril and valsartan in the presence of a sodium ion source in one or more solvents to obtain a solution; and obtaining the trisodium salt of valsartan sacubitril complex by the removal of the solvent from the solution or by adding an anti-solvent to the solution. The crystalline form of sacubitril sodium is characterized by x-ray powder diffraction pattern having characteristic peaks expressed in terms of 2-theta at about 6.3°, 12.0°, 13.8°, 16.5°, 18.3°, 20.0° and 23.8°±0.2° (2θ).
本发明描述了缬沙坦沙库比曲三钠盐的非晶形态以及制备该非晶形态的方法,包括:在一个或多个溶剂中,在存在钠离子源的情况下,将沙库比曲钠和缬沙坦二钠或沙库比曲和缬沙坦反应,以获得溶液;通过从溶液中去除溶剂或向溶液中加入抗溶剂来获得缬沙坦沙库比曲三钠盐。沙库比曲钠的晶体形态的特征是具有特征峰的X射线粉末衍射图谱,以2θ约为6.3°、12.0°、13.8°、16.5°、18.3°、20.0°和23.8°±0.2°(2θ)表示。
