Summary for Patent: 5,575,987
Title: Method of producing sustained-release microcapsules
Abstract:A method of producing sustained-release microcapsules containing a biologically active substance from an W/O emulsion comprising an inner aqueous phase containing said biologically active substance and an external oil phase containing a biodegradable polymer, characterized in that microcapsules formed on microencapsulation of said biologically active substance with said biodegradable polymer are heated at a temperature not lower than the glass transition temperature of said biodegradable polymer but not so high as to cause aggregation of the microcapsules. This method enables the production of very useful sustained release microcapsules adapted to release a bologically active substance at a calculated rate over a protracted time period starting immediately following administration without an initial burst within one day following administration.
