The present invention provides a structure suitable for controlling the release quantity of an active ingredient in a state where the structure is in contact with skin. A structure 10 according to the present invention includes a retention part 1 that retains an active ingredient, and a release control layer 3 that controls release of the active ingredient to an outside. In the structure 10, at least one of the following conditions holds: i) the release control layer 3 includes a microporous membrane having an average pore diameter of 0.01 μm or less; and ii) the release control layer 3 is a nanofiltration membrane or a reverse osmotic membrane.

Provided is a transdermal drug delivery system comprising dronabinol. The dronabinol transdermal delivery system provides a drug plasma concentration at predetermined rate for a predetermined period of time, offering a simplified therapeutic regimen by decreasing dosing frequency for the treatment and/or prevention of nausea and/or vomiting associated with, for example, chemotherapy.

The present disclosure relates to compositions, methods of use and methods of manufacturing of a transdermal delivery systems, patches, vehicles and devices used to relieve pain (i.e., analgesics) and/or inflammation that contain a pharmaceutically effective amount of a pharmaceutically acceptable and effective cannabinoid and menthol.

A wearable patch for the transdermal delivery of cannabidiol (CBD). Cannabidiol is delivered in in the form of a CBD mixture which comprises CBD oil loaded into liposomes. The CBD mixture can be delivered without the use of dermal enhancers. A transdermal patch is preloaded with the CBD mixture and placed upon the skin to penetrate the dermis layer, where the CBD mixture will diffuse into the interstitial body fluid. The patch comprises microneedles and the CBD mixture which is preloaded into or on the needles depending on the type of microneedles used.

A device for the delivery of an agent to an intestinal site has a backing element, a mucoadhesive element for adhering the device to the intestinal site, and a reservoir comprising the agent. The mucoadhesive element includes a polymer, an opposing surface having the capacity to adhere to the intestinal site, and a population of passageway(s) extending from the reservoir to the opposing surface for delivery of the agent from the reservoir to the intestinal site, each of the passageway(s) having a minimum diameter greater than 10 microns, the diameter being determined by cryogenic scanning electron microscopy after 30 minutes of hydration at 20° C. in phosphate buffered saline at pH 6.5.

Devices, systems, compositions and methods for long term or prolonged transdermal administration of an active agent are provided.

The disclosure provides complexes for desired usage as as chemical groups that enhance delivery of moieties from a buccal setting or from a transdermal patch, where the CBD unexepectely enhances the transmission and availability of actives.

A oil treatment system, method and device are disclosed. An oil impregnated treatment pad is attachable to a carrier, with a heat pad attachable to the carrier, so as to deliver the treatment to a user with a heat source adjacent to the treatment pad.

Provided is a transdermal drug delivery system comprising cannabidiol, or a cannabidiol salt alone or in combinations thereof. Transdermal delivery can provide a drug plasma concentration at predetermined rate for a predetermined period of time with a simplified therapeutic regimen by decreasing dosing frequency for the treatment and/or prevention of pain and/or inflammation.
