Abstract
The present invention relates to methods of applying a drug—polymer coating layer onto an implantable medical device or another substrate, and the use of a choice of solvents to adjust the release of the drug from the coating. The drug to polymer ratio is about 1:1 to 1:3 on a mass basis. The polymer and the drug are hydrophobic.
