  • Patent number: 11166974
    Abstract: Regarding Diquafosol ophthalmic solution comprising a chelating agent at a concentration of 0.0001 to 1% (w/v), formation of insoluble precipitates found in Diquafosol ophthalmic solution during storage of the solution, as well as deterioration of the filtration performance in the course of production (course of filtration sterilization), have been inhibited. Further, in Diquafosol ophthalmic solution comprising a chelating agent, reduction of eye irritation and enhancement of the preservative effectiveness have been confirmed, in comparison to Diquafosol ophthalmic solution comprising no chelating agent. Accordingly, the present invention has been confirmed to provide physicochemical properties that are stable during the courses of production and distribution as well as the course of storage by a patient, and also reduce eye irritation and enhance preservative effectiveness.

  • Patent number: 9254306
    Abstract: An eye drop containing (i) a peptide having an amino acid sequence which is represented by Ser-Ser-Ser-Arg (“SSSR”), or a pharmaceutically acceptable salt thereof and (ii) a peptide having an amino acid sequence represented by Phe-Gly-Leu-Met-NH2 (“FGLM”), or a pharmaceutically acceptable salt thereof. The concentration ratio of the SSSR or a pharmaceutically acceptable salt thereof and the FGLM or a pharmaceutically acceptable salt thereof is 1/15 and 1/50. The concentration of the SSSR or a pharmaceutically acceptable salt thereof is 0.001% to 0.3% (w/v), and the concentration of the FGLM or a pharmaceutically acceptable salt thereof is 0.015% to 1.5% (w/v). The pH of the eye drop is 2.5 to 6.5. The eye drop serves to minimize the occurrence of side effects and serves to improve its storage stability.

  • Patent number: 9170472
    Abstract: According to an aspect, a portable photographing device includes: an image capturing unit; a projecting unit for projecting an image; and a storing unit for storing an image captured by the image capturing unit. The projecting unit projects any of a first image captured by the image capturing unit, a second image related to the first image, and a third image obtained by synthesizing the first image with the second image as a projection image into a region which is different from an image capturing region of the photographing unit. The storing unit stores the first image in the projection of the projection image or the first image after the projection of the projection image.
