  • DRUG COATED BALLOON CATHETER AND PHARMACOKINETIC PROFILE
    Publication number: 20140046254
    Abstract: A drug delivery balloon is provided comprising a balloon having a surface, and a coating disposed on at least a portion of the balloon surface, the coating including an cytostatic therapeutic agent, an excipient, and a plasticizer. In accordance with the present subject matter, at least 30% of the coating transfers from the balloon surface within two minutes after inflation of the balloon. Alternatively, at least 30% of the coating transfers from the balloon surface within one minute after inflation. The coating results in an effective pharmacokinetic profile of an cytostatic therapeutic agent in a vasculature or target tissue.
