Abstract
The disclosure relates to medical devices coated with zein admixed with levulinic acid. The medical device may further include a therapeutic agent in contact with zein admixed with levulinic acid. Zein admixed with levulinic acid allows the therapeutic agent to be retained on the device during delivery and also controls the elution rate of the therapeutic agent following implantation. The disclosure further relates to methods of delivering a therapeutic agent on said medical devices as well as their use especially in the form of stents for prevention of restenosis.
