    摘要: The present invention provides a tetomilast crystal that is industrially easily produced in a large volume. (1) a tetomilast hydrate crystal having a powder X-ray diffraction spectrum that is substantially the same as the powder X-ray diffraction spectrum shown in Fig. 2; (2) an anhydrous tetomilast type A crystal having a powder X-ray diffraction spectrum that is substantially the same as the powder X-ray diffraction spectrum shown in Fig. 4; (3) an anhydrous tetomilast type C crystal having a powder X-ray diffraction spectrum that is substantially the same as the powder X-ray diffraction spectrum shown in Fig. 8; (4) a tetomilast acetonitrile solvate crystal having a powder X-ray diffraction spectrum that is substantially the same as the powder X-ray diffraction spectrum shown in Fig. 10; and (5) a mixture consisting of the above anhydrous tetomilast type A crystal and an anhydrous tetomilast type B crystal. These crystals are stable towards heat and moisture, and are also excellent in terms of the disintegration property and dissolution property of tablets. Accordingly, these crystals are preferably used as pharmaceutical compositions.

    摘要: The present invention provides a novel method for producing fine particles of aripiprazole anhydride crystals B. The method for producing fine particles of aripiprazole anhydride crystals B comprises the steps of: (1) heating and dissolving crude aripiprazole in a lower alcohol, and subsequently cooling the resulting mixture to precipitate crystals to obtain crystals of aripiprazole lower alcohol solvate; (2) subjecting the crystals of aripiprazole lower alcohol solvate to wet-milling in the form of a slurry containing the lower alcohol; and (3) subjecting the dispersion of the wet-milled crystals to solid-liquid separation to obtain the crystals, and heating the crystals.
