PROCESS TO PREPARE MICROPARTICLES. |
| abstract |
A process for preparing microparticles comprising a biologically active material and a polymer and having an average particle size expressed as the average volume diameter (VMD) of from 10 to 500 µm, where the biologically active material is substantially insoluble in the polymer , process that includes: a. contacting a mixture of the biologically active material or a precursor thereof, the polymer or a precursor thereof and a processing aid with a supercritical fluid that is capable of sponging the polymer under the conditions of temperature and pressure necessary to maintain the fluid in a supercritical state; b. allow the supercritical fluid to penetrate and liquefy the polymer, while maintaining the temperature and pressure conditions so that the fluid is maintained in a supercritical state; C. release the pressure to precipitate the microparticles comprising the biologically active agent and the polymer. |
