  • Patent number: 6719999
    Abstract: The present invention is directed to a formulation comprising a lipid-regulating agent dissolved in one or more non-aqueous and/or water-miscible solvents, or optionally, in a premix of one or more solvents and one or more surfactants.
    Type: Grant
    Filed: March 31, 1999
    Date of Patent: April 13, 2004
    Assignee: Abbott Laboratories
    Inventors: Rong (Ron) Liu, Qinghai Pan, Pawan Hansrani
  • Patent number: 6372251
    Abstract: The present invention is directed to a semi-solid formulation comprising a lipid-regulating agent. Said formulation is prepared by solubilizing said lipid-regulating agent in one or more liquid components to form a clear liquid solution, then solidifying said solution by adding one or more solid or semi-solid components to said solution to form a semi-solid formulation. Said formulation can melt or dissolve upon mixing with a bulk aqueous medium. The resulting formulation results in an increase in drug solubility and oral bioavailability, and an improved dissolution rate.
    Type: Grant
