    Abstract: Drug delivery systems and methods for administering a glucagon-like insulinotropic peptide to the buccal mucosa for transmucosal drug delivery are described. The drug delivery systems comprise a drug composition containing an effective amount of the glucagon-like insulinotropic peptide and an effective amount of a permeation enhancer for enhancing permeation of glucagon-like insulinotropic peptide through the buccal mucosa and means for maintaining the drug composition in a drug transferring relationship with with buccal mucosa. These systems can be in free form, such as creams, gels, and ointments, or can comprise a device of determined physical form, such as tablets, patches, and troches. A preferred glucagon-like insulinotropic peptide is GLP-1(7-36)amide.

    Abstract: A method and system for mucosally administering a macromolecular drug to mucosa of the oral cavity is shown. The system comprises an inner drug/enhancer/polymer layer having one surface adapted to contact and adhere to the mucosal tissue of the oral cavity and an opposing surface in contact with and adhering to an overlying inert layer. The inner layer contains from about two to sixty percent by weight of a bile salt enhancer, five to sixty five percent by weight of a hydrophilic polymer which is water soluble or swellable and an effective amount of a macromolecular drug having a molecular weight of at least 500 daltons. Polysaccharides, polypeptides and proteins are preferred forms of macromolecular drugs. The bile salt enhancer facilitates the delivery of macromolecules such as low molecular weight heparin and calcitonin. The polymer serves as a plasticizer to prevent the crystallization and/or aggregation of such macromolecular drugs. Hydroxypropyl cellulose is a particularly suitable polymer.

    Abstract: The present invention is directed to novel methods and apparatus for noninvasive blood glucose monitoring. Blood glucose is monitored noninvasively by correlation with amount of glucose which permeates an epithelial membrane, such as skin or a mucosal membrane, into a glucose receiving medium over a specified time period. The glucose receiving medium preferably includes a glucose permeation enhancer capable of increasing the glucose permeability across the epithelial membrane. The glucose receiving medium is positioned against the epithelial membrane so that the permeation enhancer alters the permeability of the membrane. After sufficient time delay, the glucose receiving medium is removed and analyzed for the presence of glucose using conventional analytical techniques.The apparatus within the scope of the present invention includes means for supporting the glucose receiving medium. Such means for supporting the glucose receiving medium may include a housing defining a receiving chamber therein which holds the glucose receiving medium and an opening to the receiving chamber. The means for supporting the glucose receiving medium may also include a hydrogel. The apparatus also preferably includes means for temporarily positioning the glucose receiving medium against the epithelial membrane.
