  • Patent number: 9943484
    Abstract: The present invention relates to preparation of biodegradable microparticles formed from polylactide-polyglycolide copolymers (PLGA) polymer and how to achieve sigmoidal release of active pharmaceutical compound from the microparticles. In particular, the present invention relates to emulsification of an inner/oil phase to an outer/water phase followed by quenching and a single drying step for the preparation of microparticles having a preferred release profile of preferably basic/nucleophilic compounds such as risperidone. Alternatively the present invention is also suitable for hydrophobic compounds that have poor water-solubility and a high drug loading of >20% w/w is required. The release profile can be controlled by adjusting the degree of saturation of the outer/water phase with the organic solvent used in the inner/oil phase, the polymer concentration of the inner/oil phase and the temperature at the quenching step.

  • Patent number: 9849147
    Abstract: The present invention relates to a fast dissolving tablet comprising a therapeutically effective amount of a phosphate binding polymer, such as sevelamer or pharmaceutically acceptable salt or derivative thereof, that exhibit limited swelling in the oral cavity, has pleasant taste and mouth feel, high phosphate binding capacity with fast binding kinetics and require limited amount of water intake. A process for the preparation thereof is disclosed.
