ABSTRACT:
This disclosure relates to endolumenal medical devices coated with a taxane therapeutic agent in one or more solid form(s) having varying dissolution rates. Particularly preferred coatings comprise amorphous paclitaxel, dihydrate paclitaxel, or combinations thereof that provide durable coatings that release paclitaxel over a desired period of time, which can be on the order of hours, days or weeks. Preferred embodiments relate to medical device coatings of paclitaxel, or paclitaxel analogs or derivatives, having one or more polymorph solid forms that provide a prolonged release of paclitaxel within a body vessel without requiring a polymer carrier or barrier layer to achieve the desired rate of paclitaxel elution.
