Patent

CA 2743600

The present invention relates to a method for preparing microspheres and microspheres prepared thereby, more particularly to a method for preparing a polymeric microsphere, including preparing an emulsion including a polymer compound, a drug, a water- insoluble organic solvent and a dispersion solvent and adding to the prepared emulsion a base or an acid to remove the water-insoluble organic solvent from the emulsion, a polymeric microsphere prepared thereby, and a composition for drug delivery including the microsphere. According to the present invention, a drug-containing polymer microsphere may be prepared quickly and simply without the solvent evaporation or solvent extraction process, thereby reducing water consumption and minimizing wastewater generation.

La présente invention concerne un procédé de préparation de microsphères et des microsphères produites par ce procédé, plus particulièrement un procédé de préparation de microsphères polymériques, comprenant la préparation d'une émulsion comportant un composé à base de polymère, un médicament, un solvant organique non hydrosoluble et un solvant de dispersion et l'ajout à l'émulsion préparée d'une base ou d'un acide pour éliminer le solvant organique non hydrosoluble de l'émulsion, une microsphère polymérique préparée par ce procédé, et une composition pour l'administration de médicament comportant la microsphère. Selon la présente invention, une microsphère polymérique contenant un médicament peut être préparée rapidement et simplement sans procédé d'évaporation ou d'extraction de solvant, réduisant ainsi la consommation d'eau et minimisant la génération d'eaux usées.
