The object of the invention are new crystalline forms perindopril erbumine monohydrate, perindopril erbumine sesquihydrate and perindopril erbumine dihydrate and a process for the preparation thereof by dissolving perindopril erbumine in water or in water under the addition of a volatile water-miscible polar organic solvent, freezing and lyophilizing.
Another object of the invention is a new process for the preparation of perindopril erbumine monohydrate in pure crystalline form by freezing aqueous acetone solutions and lyophilizing.
Another object of the invention are pharmaceutical formulations for the treatment of arterial hypertension and with vasodilatory activity, containing a therapeutically effective amount of these new crystalline forms.
本发明的目的是新的晶体形式perindopril erbumine monohydrate、perindopril erbumine sesquihydrate和perindopril erbumine dihydrate以及通过将perindopril erbumine溶解在
水中或在添加挥发性的
水相互溶性极性有机溶剂的
水中,冷冻和冻干的制备方法。本发明的另一个目的是通过冷冻
乙酸水溶液并冻干的方法制备纯晶体形式的perindopril erbumine monohydrate。本发明的另一个目的是制备含有这些新的晶体形式的治疗动脉高血压和具有扩血管作用的药物配方,其中包含治疗有效量。
