atoms are arranged on the plane on the other hand the inventors have confirmed that the crystal which is the hitherto known crystal and which is recrystallized from n hexane ethyl acetate is the crystal having such a crystal habit that 11 1 plane is the specific growth surface phenyl group is arranged on this plane this plane is the plane represented by the peak provided in the vicinity of 16 u00b0 as the value of 20 in the powder x ray diffraction measurement the pharmaceutical composition of the present invention is characterized in that the pharmaceutical composition comprises the crystal of the present invention or the active pharmaceutical ingredient of the present invention it is estimated that the crystal as described above is excellent in the solubility in the polar solvent as for the production method for producing the pharmaceutical composition of the present invention the pharmaceutical composition can be produced in the same manner as in the conventional production method for producing the pharmaceutical composition comprising luliconazole except that the crystal of the present invention or the active pharmaceutical ingredient of the present invention is comprised it is estimated that the crystal of the present invention or the active pharmaceutical ingredient of the present invention is excellent in the solubility in the polar solvent and the crystal of the present invention or the active pharmaceutical ingredient of the present invention is excellent in the solubility in the polar solvent such as alcohol or the like therefore it is preferable to provide a pharmaceutical preparation which includes the dissolving step in.
