  • Patent number: 5330768
    Abstract: A new series of degradable polymeric matrices were prepared by blending polymers that degrade by hydrolysis such as poly(L-lactic acid)(PLA), and nonionic Pluronic.TM. surfactants, block copolymers of polyethyleneoxide (PEO) and polypropyleneoxide (PPO). The water content of the polymer blend films was controlled by mixing different types of block copolymers and by adjusting their amount. In aqueous solution, the blends revealed the typical liquid-crystalline phase transition of Pluronic.TM. polymers, suggesting the formation of a gel-like structure within the polymer skeleton. Poly(lactic acid) degradation rates were not affected by the blending procedure, although the hydration degree in these matrices was higher. When used as drug-releasing matrices, these blends extended protein release and minimized the initial protein burst, as compared to the pure polymer.

  • Patent number: 5164193
    Abstract: A sustained-release tablet is disclosed. The tablet is a combination of powder (A) comprising an oil component, water insoluble polymer, or both, and a pharmaceutically active component and powder (B) comprising a water soluble polymer and a pharmaceutically active component. An ideal release rate for individual pharmaceutically active component can easily be ensured by controlling its release rate by changing the ratio of powders (A) and (B).

  • Patent number: 5023081
    Abstract: Controlled release microspheres of hydroxybutyrate polymer comprise active ingredient and hydroxybutyrate/hydrovalerate copolymer. The microspheres comprise a skin which is distinct from the general bulk of the microspheres, and this skin may have a porosity covering from 0-50% of the total surface area of the microsphere, this porosity being largely controlled by varying the hydroxyvalerate content of the polymer. The porosity of the interior of the microspheres can also be regulated. Control of the two porosities permits the attainment of a wide range of release rates for a wide range of active ingredients. The microspheres can be used in a wide variety of pharmaceutical, veterinary and agricultural applications.
