    摘要: The present invention relates to polymorphic forms of duloxetine hydrochloride, especially (duloxetine HCl), which are characterized by an X-ray diffraction pattern with peaks (2θ):9.6, 13.9, 18.0, 18.8, 19.2, 20.8, 27.4, 27.9 (designated form A) or an X-ray diffraction pattern with characteristic peaks (2θ): 12.0, 14.8, 19.8, 21.3, 21.6, 22.1, 22.4, 23.1, 24.1 (designated form T). The present invention also pertains to processes for the preparation of form A and form T, which involves dissolving duloxetine hydrochloride in particular solvents and cooling the solution to obtain crystals, that are dried.
