Unit dosage forms, devices, and kits for topical delivery of topical immunosensitizers are provided. These include dermal patches, glass swabs, and kits containing a dermal patch and a glass swab. Among other advantages, the unit dosage forms, devices, and kits presented herein deliver a more consistent and controlled volume of drug solution, prevent underdosing and overdosing, prevent or discourage repeat dosing, and provide a more consistent skin area to which the drug solution is applied.

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.

A flexible ammonia pad configured for mounting on the skin of an individual and for sealing and releasing an ammonia inhalant is provided. The pad includes a first flexible impermeable layer having bottom and top surfaces, an adhesive applied to the bottom surface, an ammonia mixture applied to the top surface, and a second flexible impermeable layer covering the top surface. The second layer has at least one outer edge sealed to the first layer and configured to releasably seal the ammonia mixture between the first and second layers. Preferably the ammonia mixture contains 2-15% of ammonia.

Novel compositions and systems for closure of wounds with antimicrobial effectiveness are disclosed. The compositions provide devices of improved flexibility and elasticity and are readily applied to wound sites or over wound closure devices. The present invention is also directed to a novel platinum catalyst for use in such compositions. The catalyst provides for rapid curing on topical surfaces such as skin and bonds to such surfaces in about 2-5 minutes.

A medical covering film and system, and a usage method and an application therefor. The medical covering film comprises a barrier film layer (10), an adsorption layer (20), and a reticular adhesive layer (30), one side of the adsorption layer (20) being composited on the barrier film layer (10), and the reticular adhesive layer (30) being composited on the other side of the adsorption layer (20); the area of an adhesive-free region (31) of the reticular adhesive layer (30) occupies 10% or more of the total area of the reticular adhesive layer (30), but not 100%. The present medical covering film can fix a preparation to the affected skin very well, is not easily squeezed off the target skin area by external force, and can maintain the moisture in the preparation very well.

A method for creating a consolidated compound for delivering an immunomodulatory and imiquimod to a patient, comprising diluting immunomodulator extract to a desired dilution by transferring a desired quantity of the concentrated immunomodulator to an associated sterile container, the associated sterile container having a defined volume of diluted immunomodulator after dilution thereof, providing a viscous encapsulation material, selecting a prescribed amount of concentrated immunomodulator, the prescribed amount defined as that amount of the diluted immunomodulator extract required to provide a number of doses equal to the number of dispensable increments from the container containing the viscous encapsulation material, introducing the selected amount of each of the diluted immunomodulator extract into the viscous encapsulation material, introducing an amount of imiquimod into the viscous encapsulation material, and mixing the introduced amount of each of the diluted immunomodulator extracts and the introduced amount of imiquimod with the viscous encapsulating material.

A composition comprising an amphiphilic polymeric material that is both hydrogen peroxide- and hypoxia-sensitive is described. The composition can further include a glucose-oxidizing enzyme and insulin, a bioactive derivative thereof, and/or another therapeutic agent (e.g., another diabetes treatment agent). The polymeric material can form vesicles that comprise single or multiple layers of the polymeric material that enclose the glucose-oxidizing enzyme and the insulin, bioactive derivative and/or other therapeutic agent. The vesicles can be loaded into microneedles to, for example, prepare microneedle arrays for skin patches. Methods of delivering insulin to a subject using the compositions, vesicles, microneedles, and/or microneedle array skin patches are also described.

The present invention falls within the area of polymeric materials based on ultrafine fibres for use in the pharmaceutical, nutraceutical and cosmetic sector, relating to the method of producing self-adhesive patches and the use thereof as a platform for the controlled release of bioactives by means of electrohydrodynamic and/or aerohydrodynamic processing techniques.

The present disclosure relates to a transdermal drug delivery device, also known as a transdermal patch that can be worn by the user anywhere the person travels throughout the day. The transdermal patch is characterized in that it is a single-layered patch comprising an liposomal emulsion carrying a drug to be administered and an adhesive which are both incorporated into a polymer or polymeric matrix. The liposomal emulsion within the single-layered transdermal patch allows the drug that is to be administered to be spread throughout the entire surface area of the transdermal patch.

Compositions and methods to produce adhesive articles with active agents concentrated at the substrate contacting surface. The active agents are applied in powder form, or in combination with a liquid or gel vehicle, to the substrate contacting surface of an adhesive layer of an adhesive article. The active agent compositions are directly applied to the adhesive layer, or are first applied to a release liner, which is then brought into contact with the adhesive layer to dispose the active agent compositions to the substrate contacting surface of the adhesive layer. Upon application of the adhesive article to a substrate, the active agent is delivered to a region of interest on the substrate.
