Method of producing a sustained-release preparation |
摘要 |
A method of producing sustained-release microcapsules which comprises dispersing a physiologically active polypeptide into a solution of a biodegradable polymer and zinc oxide in an organic solvent, followed by removing the organic solvent; which provides a sustained-release preparation showing a high entrapment ratio of the physiologically active polypeptide and its constant high blood concentration levels over a long period of time. |
