Abstract:
There is disclosed a process for the extraction of volatile solvents entrained in a polymer-based pharmaceutical composition designed for sustained release of drug over an extended period of time prepared in microcapsule form wherein the composition comprises at least one hormonally active water-soluble polypeptide in an effective amount greater than a conventional single dose and a biocompatible, bioerodable encapsulating polymer, which process comprises the steps of contacting the composition to a stream of dense gas, that is, pressurized gas and then removing the dense gas, and volatile solvents contained therein, extracted from the pharmaceutical composition.
Abstract:
This invention relates to compositions for the sustained release of biologically active polypeptides, and methods of forming and using said compositions, for the sustained release of biologically active polypeptides. The sustained release compositions of this invention comprise a biocompatible polymer having dispersed therein, a biologically active polypeptide and a sugar.
