| 摘要 |
The present invention relates to drug-eluting articles with multiple polymeric coatings arranged and constructed to provide improved drug release profiles. Specifically, the present invention relates to drug-eluting articles that each comprises a substrate, a first polymeric layer over said substrate, and a second polymeric layer over said first polymeric layer. The first polymeric layer comprises at least a first biocompatible polymer and at least a first pharmacologically active compound that is encapsulated in the first biocompatible polymer. The second polymeric layer comprises at least a second biocompatible polymer having a degradability that is higher than that of the first biocompatible polymer. |
