A drug delivery system is provided in the form of a controlled release, bioerodible pellet for subdermal implantation. The pellet is bioerodible, and provides for the sustained release of a pharmacologically active agent over an extended time period. As such, the drug delivery system finds significant utility in chronic drug administration. Bioerosion products are water soluble, bioresorbed, or both, obviating the need for surgical removal of the implant. Methods for manufacturing and using the drug delivery system are also provided.
