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.
The present invention relates to new salts of perindopril, particularly to a new calcium salt and new amine salts of perindopril, to a process for their preparation and to a pharmaceutical formulations containing the new salts.
