ABSTRACT:
A method of enhancing the drug release rate from a composite material. The composite material includes a synthetic, bioabsorbable polymer matrix and a drug particle phase dispersed therein. The release rate of the drug from the polymer matrix is enhanced by orienting the composite material. The drug release rate of the oriented composite material is greater than the drug release rate from an otherwise comparable non-oriented composite material.
