摘要

Method for preparation of solid microparticles containing at least one active ingredient (I). Method for preparation of solid microparticles containing at least one active ingredient (I) comprises (a) making a solution (A) of at least one biodegradable, biocompatible and water-insoluble polymer (P) in a biocompatible and water-miscible solvent (S); (b) dissolving or suspending at least one hydrophilic or hydrophobic (I) in the solution, forming (B); (c) emulsifying (B), optionally in presence of a surfactant, in a plant oil that forms the continuous hydrophobic phase; and (d), the new feature, extraction of (S) by adding at least one biocompatible hydrophobic oil (O), with gentle stirring, until solid microparticles of (P), containing (I), have formed. An Independent claim is also included for microparticles (MP) containing (I) prepared by the new method.
