MICROCAPSULES PREPARED USING ETHYL OR ISOPROPYL ESTERS OF FATTY ACIDS AND PHARMACEUTICAL COMPOSITIONS |
摘要 |
A process for microencapsulating bioactive substances in biocompatible polymers according to the phase-separation principle, wherein an excess of an ethyl or isopropyl ester of a straight-chain fatty acid having 12-18 carbon atoms is used as the hardening liquid, and the pharmaceutical compositions containing the microcapsules prepared by this process. Isopropyl myristate and isopropyl palmitate are preferred hardening liquids. |
