  • Publication number: 20230025836
    Abstract: The present invention relates to an ophthalmic preparation containing an active ingredient selected from 3-phenyl-4-propyl-1-(pyridin-2-yl)-1H-pyrazol-5-ol compound or a pharmaceutically acceptable salt thereof. The eye drop according to the present invention is excellent in stability and safety and shows an excellent effect on prevention or treatment of eye diseases in such a way that an active ingredient thereof reaches a posterior segment of an eyeball simply through instillation rather than a direct injection into an eyeball.

  • Patent number: 10918725
    Abstract: An ophthalmic composition is provided that includes rebamipide and a method for preparing the same. The ophthalmic composition of maintains its transparency for a long time even in a physiologically neutral to weakly basic pH range that does not injure the cornea and conjunctiva of a patient suffering from dry eye and has improved stability so as not to be re-dispersed.

  • Publication number: 20190038564
    Abstract: Disclosed is an immediate-release carvedilol formulation, which is configured such that a coating layer including a polymer, wax, fatty acid and/or fatty acid ester is formed on the surface thereof. This formulation has improved madescent, and thus can exhibit high stability, in which the initial appearance of the formulation can be maintained without cracking or breaking even under storage conditions at high relative humidity.

  • Publication number: 20080226579
    Abstract: The present invention is a novel resinate complex of (+)-clopidogrel optical isomer, wherein the (+)-clopidogrel isomer is bounded to a water-soluble cation exchange resin having sulfonic acid groups. The novel resinate complex has recognized some advantages in that (1) its chemical structure is stable, and (2) it can be formulated into a solid form that may provide taste-masking capabilities associated with bitter drugs (e.g., strong irritation, bitterness and sour taste), thus requiring no drink of water.

  • Publication number: 20080153785
    Abstract: Provided is a pharmaceutical composition having improved oral absorption of a bisphosphonate drug, comprising at least one active substance selected from bisphosphonate drugs having non-permeability to a lipid biomembrane due to ionization and high water-solubility in vivo and having bioavailability of less than 10%, and at least one selected from biocompatible water-soluble chitosan, as essential ingredients.

  • Publication number: 20060019872
    Abstract: Disclosed herein is a pharmaceutical composition for oral absorption of polar drugs. The composition consists essentially of (a) at least one polar active substance having a bioavailability of less than 30% which is poorly absorptive through lipid membranes because of its high hydrophilicity and charged ion; (b) at least one organic alkalizing agent having an amino acid or polyol structure which shows alkalinity in aqueous solution and is ionically bonded to the polar active substance; and (c) at least one surfactant having a C6-18 fatty acid structure which has an HLB of 4 to 18. Alternatively, the composition consists essentially of (d) at least one organic alkalizing agent having the characteristics of both the organic alkalizing agent and the surfactant instead of the organic alkalizing agent and the surfactant. The composition enables polar active drugs to penetrate the gastro-intestinal membrane and oral dosage forms to be substituted for injections.
