摘要：
A method for depositing a coating comprising a polymer and pharmaceuticalagent on a substrate, comprising the following steps: discharging at least onepharmaceutical agent in a therapeutically desirable morphology in dry powderform through a first orifice； discharging at least one polymer in dry powderform through a second orifice； depositing the polymer and/or pharmaceuticalparticles onto said substrate, wherein an electrical potential is maintainedbetween the substrate and the pharmaceutical and/or polymer particles, therebyforming said coating； and sintering said coating under conditions that do notsubstantially modify the morphology of said pharmaceutical agent.
