  • Publication number: 20250009767
    Abstract: An adhesive oral disc for sustained release of cannabinoids is presented. The disc includes one or more cannabinoids and is composed of at least a mucosal contacting layer having a mucosal contacting surface operable to be fixed to the gingiva of a person in need of alleviation or treatment of a medical condition, where the mucosal contacting layer includes one or more mucoadhesive polymers allowing the adhesive oral disc to adhere to the gingiva for an extended period of time. Further, the disc includes a non-mucoadhesive module fused to the mucosal contacting layer, where the non-mucoadhesive module includes a solid tablet composition allowing the non-mucoadhesive module to dissolve within an extended period of time upon adhesion of the adhesive oral disc to the gingiva. The invention is particularly useful for alleviation or treatment of ulcers.
