Abstract
The present invention relates to a drug-containing polymeric composition comprising at least one therapeutic agent encapsulated in at least one biocompatible polymer, wherein at least a portion of the therapeutic agent in this polymeric composition is crystalline. The at least one biocompatible polymer may form a substantially continuous polymeric matrix with the at least one therapeutic agent encapsulated therein. Alternatively, the at least one biocompatible polymer may form polymeric particles with the at least one therapeutic agent encapsulated therein.
