PROBLEM TO BE SOLVED: To provide a pharmaceutical preparation capable of suppressing decomposition of rebamipide by light.SOLUTION: There is provided a pharmaceutical preparation in which an aqueous pharmaceutical composition comprising at least one selected from the group consisting of rebamipide, a rebamipide derivative and a salt thereof is stored in a container for shielding light having a wavelength of 270 to 280 nm. There is provided a pharmaceutical preparation in which, preferably, the maximum transmittance of light having a wavelength of 400 to 700 nm in the container is 60% or more. In addition, the container preferably shields light having a wavelength of 300 to 700 nm.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】光によるレバミピドの分解を抑制できる医薬製剤の提供。【解決手段】レバミピド、レバミピド誘導体、及びそれらの塩からなる群から選択される少なくとも1種を含有する水性医薬組成物が、波長270~280nmの光線を遮断する容器に収容されている、医薬製剤。前記容器が更に波長400~700nmの光線の最大透過率が60%以上であることが好ましい医薬製剤。その上波長300~700nmの光線の遮断する容器であることが好ましい医薬製剤。【選択図】なし
