Title:Pharmaceutical carrier device suitable for delivery of pharmaceutical compounds to mucosal surfaces
Abstract:The present invention relates to a pharmaceutical delivery device for application of a pharmaceutical to mucosal surfaces. The device comprises an adhesive layer and a non-adhesive backing layer, and the pharmaceutical may be provided in either or both layers. Upon application, the device adheres to the mucosal surface, providing localized drug delivery and protection to the treatment site. The kinetics of erodability are easily adjusted by varying the number of layers and/or the components.
