PHARMACEUTICAL COMPOSITION CONTAINING (R)-N-1-(3,5-DIFLUORO-4-METHANSULFONYLAMINO-PHENYL)-ETHYL-3-(2-PROPYL-6-TRIFLUOROMETHYL-PYRIDIN-3-YL)-ACRYLAMIDE AND METHOD FOR INHIBITING CRYSTAL FORMATION THEREOF

摘要

The present invention relates to a pharmaceutical composition, containing (R)-N-[1-(3,5-difluoro-4-methansulfonylamino-phenyl)-ethyl]-3-(2-propyl-6-trifluoromethyl-pyridin-3-yl)-acrylamide as a first ingredient and containing a vinylpyrrolidone-based polymer as a second ingredient. The composition of the present invention has a formulation characteristic in which the crystal formation of a compound represented by chemical formula 1 is delayed for a long time.
