  • Patent number: 11633409
    Abstract: The present invention provides a solid preparation comprising, based on 100 parts by weight of the solid preparation, a self-emulsifying composition comprising 0.1 to 0.5 parts by weight of dutasteride, 6 to 110 parts by weight of oil and 6 to 110 parts by weight of a surfactant, and 5 to 185 parts by weight of a coating excipient having pores accommodating the self-emulsifying composition formed in a surface thereof, and a method of manufacturing the solid preparation.
    Type: Grant
    Filed: August 30, 2018
    Date of Patent: April 25, 2023
    Assignee: JW PHARMACEUTICAL CORPORATION

  • Patent number: 10722585
    Abstract: Disclosed is a pharmaceutical composition, comprising: a) at least one sorbitan unsaturated fatty acid ester having a polar head with at least two or more —OH (hydroxyl) groups; b) at least one phospholipid; c) at least one liquid crystal hardener which is free of an ionizable group and has a triacyl group with 15 to 40 carbon atoms or a carbon ring structure in a hydrophobic moiety; and d) at least one GnRH (gonadotropin-releasing hormone) analogue as a pharmacologically active substance, wherein said lipid pre-concentrate exists as a liquid phase in absence of aqueous fluid and forms into a liquid crystal in presence of aqueous fluid. The pharmaceutical composition is configured to enhance the sustained release of the pharmacologically active substance GnRH analogue.

  • Publication number: 20150265535
    Abstract: Disclosed is a sustained-release lipid pre-concentrate, comprising: a) at least one liquid crystal former; b) at least one neutral phospholipid; c) at least one liquid crystal hardener; and d) at least one anionic anchoring agent, wherein the sustained-release pre-concentrate exists as a lipid liquid phase in the absence of aqueous fluid and forms into a liquid crystal upon exposure to aqueous fluid. The sustained-release lipid pre-concentrate is configured to enhance the sustained release of cationic pharmacologically active substance through ionic interaction between the anionic anchoring agent and the cationic pharmacologically active substance.
