  • Taste-masked drugs in rupturing multiparticulates
    Patent number: 8236349
    Abstract: A pharmaceutical composition comprises multiparticulates comprising a drug, a matrix material, and swelling agent. In one aspect, the multiparticulates comprise a core comprising a drug, and a coating surrounding the core. The coating is selected from the group consisting of (i) a water-permeable, substantially drug-impermeable coating, and (ii) an anti-enteric coating.

  • Microparticles of lactide-co-glycolide copolymers and methods of making and using the same
    Patent number: 6319521
    Abstract: The present invention relates to the formation of microparticles from copolymers during a process involving precipitation with compressed antisolvents. The family of suitable copolymers have a semi-crystalline structure that above their glass transition temperature retain sufficient crystalline strength to form microparticles. The invention also provides systems comprising the microparticles encapsulated with a desired compound for the controlled release of the compound over a predetermined period of time.
