    Abstract: PROBLEM TO BE SOLVED: To provide an efletirizine which is a pharmaceutical having excellent antihistaminic properties, namely, a new crystal form of a 2-[2-[4-[bis (4-fluorophenyl) methyl]-1-piperazinyl]ethoxy]acetic acid dihydrochloride, and to provide a method for preparation of the crystal and to a pharmaceutical composition comprising the same.
    SOLUTION: The invention relates to the new pseudopolymorphic forms of 2-[2-[4-[bis(4- fluorophenyl)methyl]-1-piperazinyl]ethoxy]acetic acid dihydrochloride, defined by the X-ray diffraction pattern, namely, anhydrous 2-[2-[4-[bis(4-fluorophenyl)methyl]-l-piperazinyl]ethoxy]acetic acid dihydrochloride and a monohydrate of the crystal, and relates to the method for preparation of the pseudopolymorphic crystal. The invention also relates to the pharmaceutical composition comprising the pseudopolymorphic crystal, slow release excipient and a cyclodextrine.
