US Patent No: 9814805
Coatings for controlled release of highly water soluble drugs
Abstract
The present disclosure relates to multilayer coatings that include a hydrophobic encasing layer and allow controlled release of a water soluble drug. The encasing layer encases water soluble, or hydrophilic, drugs with a flexible layer and comes in good intimate contact with the water soluble drug layer. Thus, the encasing layer conforms to the water soluble drug and can control the release of the drug. Advantageously, major cuts or fissures in the coating do not cause the water soluble drug to leak or burst out; rather, the encasing layer continues to provide modulated release of the drug. The present disclosure also includes methods of making the multilayer coatings, methods of using the multilayer coatings, and articles that include the multilayer coatings.
