ABSTRACT:
The field of this invention is the encapsulation of therapeutic or diagnostic substances in minute capsules or spheres from which the substances are slowly released over a prescribed period of time. The general processes for preparing such capsules or spheres include coacervation or a related process by means of which liquid droplets can be encapsulated, and solid phase entrapment in which the water-soluble agent is dispersed in a solid matrix material. The method of this invention can be classified as an improved procedure for matrix encapsulation or entrapment.
