This disclosure relates to implantable medical devices coated with a taxane therapeutic agent, such as paclitaxel, in one or more solid form(s) having varying dissolution rates. Particularly preferred coatings comprise amorphous and/or solvated solid forms of taxane therapeutic agents that provide durable coatings that release the taxane over a desired period of time, which can be varied in the absence of a polymer by selecting the type and amount of solid forms of the taxane therapeutic agent in the coating. Other preferred embodiments relate to methods of coating medical devices and methods of treatment. The coatings can provide a sustained release of the taxane therapeutic agent within a body vessel without containing a polymer to achieve the desired rate of paclitaxel elution.
本公开涉及涂有
紫杉醇治疗剂(如
紫杉醇)的植入式医疗器械,其具有不同溶解速率的一个或多个固态形式的涂层。特别优选的涂层包括无定形和/或溶剂化的
紫杉醇治疗剂的固态形式,其提供持久的涂层,可以在不含聚合物的情况下通过选择涂层中的治疗剂的固态形式的类型和数量来改变所需的释放时间。其他优选实施例涉及涂覆医疗器械的方法和治疗方法。这些涂层可以在不含聚合物的情况下提供
紫杉醇治疗剂的持续释放,以达到所需的
紫杉醇溶出速率。
