  • Patent number: 7374779
    Abstract: The present invention pertains to pharmaceutical formulations and systems for delivery of active agents, wherein a first fraction of an active agent is suspended in a vehicle and a second fraction of active agent is solubilized in the vehicle, with the suspended fraction representing about 5 wt. % to about 80 wt. % of the active agent and the second fraction representing about 20 wt. % to about 95 wt. % of the active agent. One or more additional active agents, which may be fully solubilized, partially solubilized, or suspended, may also be present. The first and second fractions of the active agent may or may not have different release profiles. Generally, a significant fraction of the solubilized drug will release rapidly, providing for rapid onset, while the suspended drug may be formulated for delayed and/or sustained release.
    Type: Grant

  • Patent number: 7364752
    Abstract: A pharmaceutical composition is disclosed which comprises a solid dispersion of an HIV protease inhibitor in a water soluble carrier, such as PEG, having enhanced bioavailability and improved dissolution properties. The solid dispersion may optionally be encapsulated in hard gelatin capsules, compressed into a tablet, or may be granulated with a pharmaceutically acceptable granulating agent. Also disclosed are methods of making said solid dispersion and methods of treating an HIV infection employing said solid dispersion.

  • Publication number: 20030104048
    Abstract: Pharmaceutical dosage forms having a highly hydrophilic fill material and a shell encapsulating the fill material are disclosed and described. Generally, the shell has at least one plasticizing agent therein in order to provide the shell with an effective plasticity. In one aspect, the shell may have included therein an amount of plasticizing agent that is sufficient to provide the shell with an effective plasticity upon migration of a portion of the plasticizing agent into the fill material. In another aspect, the plasticizing agent may have a solubility in the fill material of less than about 10% w/w. In yet another aspect, a combination of a plasticizing agent, and a plasticizing agent having a solubility in the fill material of less than about 10% w/w, may be presented in a total amount sufficient to provide the shell with an effective plasticity upon migration of plasticizing agent into the fill material.

  • Patent number: 6033685
    Abstract: The present invention provides a tablet for the controlled release of an active agent comprising (a) a matrix layer comprising an active agent embedded in a non-swelling, non-gelling hydrophobic matrix; (b) a first barrier layer laminated to a single face of the matrix layer; and (c) an optional second barrier layer laminated to the opposite face of the matrix layer and oppositely disposed to the first barrier layer; wherein the matrix comprises up to about 80% active agent and from about 5% to about 80% by weight of nonswellable waxes or polymeric material insoluble in aqueous medium, and the first and second barrier layers independently comprise (1) polymeric material exhibiting a high degree of swelling and gelling in aqueous medium or (2) nonswellable wax or polymeric material insoluble in aqueous medium.
