Abstract
A method for coating a medical device includes applying a second layer that includes a second drug on a first layer of on the medical device. The first layer includes a first drug, which may be in crystalline form. By selecting an appropriate solvent use in applying the second layer and appropriate process conditions, the second layer may be applied such that the first drug retains one or more therapeutic properties. For example, the second layer may be applied such that the first drug maintains its crystalline form. The first and second layers may be free of polymer.
