ABSTRACT:
A drug delivery for administering drug to an aqueous body environment at a substantially constant rate. The devices consist essentially of a mixture of drug of specific average particle size dispersed in a polymer of specific water permeability, tensile strength, and Young's modulus in specific volume proportions such that the particles are surrounded substantially individually by the polymer. The constancy of the release rate of drug from the devices is governed by the drug particle size and volume proportion of drug in the mixture.
