The present invention relates to an improved method of making drug delivery devices for the controlled release of pharmacologically active agents and further, to drug delivery devices made by such method. More specifically, the present invention relates to a method of forming a film comprising one or more biodegradable polymeric materials, one or more pharmacologically active agents, and one or more biocompatible solvents. The film is then partially dried, rolled or otherwise shaped, and then compressed. In this manner, the amount of pharmacologically active agent(s) that can be incorporated into the drug delivery device is increased and the pharmacologically active agent(s) is/are substantially homogeneously distributed throughout the drug delivery device. As a result, the release characteristics of the pharmacologically active agent from the drug delivery device are enhanced.
