Abstract
Transdermal delivery devices for the delivery of cannabidiol (CBD) are shown and described. In reservoir patch designs, a microporous, hydrophilic membrane and a backing define a reservoir that houses a mixture of CBD, a polar liquid, and a gelling agent. The hydrophilic membrane is coated with an amine-compatible silicone skin adhesive. In a monolithic design, a release liner is coated with a mixture of CBD and a PIB or amine-compatible silicone skin adhesive laminated to the backing material. In either design, the CBD may be provided as a pure compound or as a component of a cannabis oil.
Claims18
A transdermal patch formulation with cannabidiol (CBD) in polyisobutylene (PIB) adhesive, from 1% to 30%, and vitamin C palmitate.
A transdermal patch formulation with CBD and PIB adhesive with CBD concentration in solid adhesives from 1% to 30% and penetration enhancers in range of 0% to 10%, the CBD being crystalline CBD, further comprising less than 5% terpenes transmitted to skin.
A device capable of transdermally delivering cannabidiol (CBD) to a person, comprising a device housing, at least one of a liquid saturated matrix and a saturated alcohol solution;
- a removable release liner at the first side of a porous hydrophylic membrane;
- a porous, hydrophilic membrane comprising a first side, wherein the first side is capable of contacting with the person's skin;
- and
- wherein the device is capable of maintaining in contact with the person's skin for a period of time sufficient to deliver the therapeuticially effective amount of cannabidiol to the person.
A device for the transdermal delivery of cannabidiol, comprising:
- a backing;
- a release liner;
- a mixture of an adhesive and a therapeutically effective amount of cannabidiol coated on the release liner,
- wherein the adhesive comprises a polyisobutylene adhesive having a viscosity-average molecular weight ranging from about 30,000 Daltons to about 70,000 Daltons, and
- the mixture has a first surface adhered to the backing and a second, skin-adhering surface to which the release liner is removably adhered.
