  • Sustained-release lipid pre-concentrate of GNRH analogues and pharmaceutical composition comprising the same
    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.
    Type: Grant

  • SUSTAINED-RELEASE LIPID PRE-CONCENTRATE OF ANIONIC PHARMACOLOGICALLY ACTIVE SUBSTANCES AND PHARMACEUTICAL COMPOSITION COMPRISING THE SAME
    Publication number: 20150290322
    Abstract: Disclosed is a sustained-release lipid pre-concentrate, comprising: a) at least one liquid crystal former; b) at least one phospholipid; c) at least one liquid crystal hardener; and d) at least one bi- or multivalent metal salt, 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 anionic pharmacologically active substances through ionic interaction between the bi- or multivalent metal salt and the anionic pharmacologically active substances.
