IMPLANTABLE AND BIODEGRADABLE DRUG DELIVERY DEVICES AND METHODS OF USE THEREOF

Abstract

Provided are implantable and biodegradable drug delivery devices capable of delivering an active pharmaceutical ingredient (API) directly to a target tissue site. The drug delivery devices can include at least two layers. One of the layers can include the API and a biodegradable polymer and a second layer can include another biodegradable polymer that degrades slower than the first biodegradable polymer. When the device is placed directly on the target tissue, the API layer can degrade thereby releasing the API towards the target tissue while the non-API layer can prevent the API from being released away from the target tissue onto non-target tissue.
