Abstract

See full text

This invention relates to a polyamide rate-modulated monolithic drug delivery system comprising at least one active compound and a biodegradable and biocompatible polyamide polymer. The polymer is selected for delivering, in use, the active compound, within a predetermined time frame depending on the biodegradable properties of the polymer, to a target organism or organisms. In one embodiment of the invention the polymer is modified by salting-out or crosslinking the polymeric material to achieve the desired biodegradability characteristics and, consequently, to control the release of the active compound.
