Dihydrochloride pseudo-polymorphous forms of 2-[2-[4-[bis(4-fluorophenyl)methyl]-1-piperazinyl]ethoxy]acetic acid

摘要

The present invention relates to new pseudopolymorphic forms of 2-Ä2-Ä4-Äbis(4-fluorophenyl)methylÜ-1-piperazinylÜethoxyÜacetic acid dihydrochloride, namely, anhydrous 2-Ä2-Ä4-Äbis(4-fluorophenyl)methylÜ-1-piperazinylÜethoxyÜacetic acid dihydrochloride and 2-Ä2-Ä4-Äbis(4-fluorophenyl)methylÜ-1-piperazinylÜethoxyÜacetic acid dihydrochloride monohydrate. It also relates to processes for the preparation of these pseudopolymorphic forms and to pharmaceutical compositions containing them.
