  • Patent number: 6221400
    Abstract: The present invention describes formulations of nanoparticulate HIV protease inhibitors comprising a cellulosic surface stabilizer. The nanoparticulate formulations have an increased rate of dissolution in vitro, an increased rate of absorption in vivo, a decreased fed/fasted ratio variability, and a decreased variability in absorption. The present invention is also directed to methods of making the novel formulations. In particular, nanoparticulate formulations of HIV type 1 (HIV-1) and type 2 (HIV-2) protease inhibitors are described.
    Type: Grant

  • Patent number: 5705194
    Abstract: There is disclosed a pharmaceutical composition which gels at physiological temperature. The composition is comprised of a block copolymer containing one or more polyoxyethylene blocks and one or more polyoxy (higher alkylene) blocks wherein at least some of the blocks are linked together by a linking group characterised in that the linking group is an oxymethylene group, and a therapeutic agent. The therapeutic agent is present as (i) nanoparticles of the therapeutic agent having the block copolymer adsorbed on the surface thereof, (ii) a suspension in a solution of the block copolymer, or (iii) as an aqueous solution in a solution of the block copolymer.

  • Patent number: 5665330
    Abstract: The invention provides a novel compound having the structure ##STR1## wherein R is alkyl and R1, R2, R3 and R4 are each independently OCH3, H or I and n is 0 or 1 and m is 0 or 1.The compound is useful in a method of treating mammals either therapeutically or imaging mammals for diagnostic purposes. Useful therapeutic areas are in treating lymph nodes and tumors and diagnostic treatment is applicable to lymph nodes, tumors and in blood pool imaging. It is particularly advantageous to link an insoluble carrier molecule with a therapeutic or imaging agent to form the structure above. This makes the conjugate insoluble and thus amenable to forming nanoparticles.

  • Patent number: 5622938
    Abstract: Dispersible particles consisting essentially of a crystalline drug substance having a surface modifier having the formula: ##STR1## wherein R is phenyl-(CH.sub.2).sub.10 CO or C.sub.12 H.sub.25 NHCO adsorbed on the surface thereof in an amount sufficient to maintain an effective average particle size of less than about 400 nm, methods for the preparation of such particles and dispersions containing the particles. Pharmaceutical compositions containing the particles exhibit unexpected bioavailability and are useful in methods of treating mammals.

  • Patent number: 5587143
    Abstract: This invention provides a composition comprised of nanoparticles containing a therapeutic or diagnostic agent having a nonionic polymeric surfactant as a surface modifier adsorbed on the surface thereof, the surfactant being a block copolymer of ethylene oxide and butylene oxide and a method of making such nanoparticles. The compositions exhibit reduced macrophage uptake and improved toxicological profiles and facilitate particle size reduction such that milling time can be reduced and/or sterile filtration of the nanoparticles can be accomplished.
