The present invention provides a risperidone-containing patch having an excellent drug release property and patch physical properties. Specifically, the present invention provides a medical patch comprising an adhesive composition comprising risperidone or a pharmaceutically acceptable salt thereof; a carboxylic acid; a fatty acid ester; and an adhesive, characterized in that said adhesive is a star-shaped acrylic block polymer having a star-shaped structure in which at least three chain polymer portions radiate from a sulfur residue of a mercapto group situated at the center, wherein the (meth)acrylic acid alkyl ester structural units having 7-17 carbon atoms account for 30-99.99% by mass of the whole structural units in said star-shaped acrylic block polymer, and at least one of said chain polymer portions has a structural unit having a copolymer structure of polymerizable monomers comprising a (meth)acrylic acid alkyl ester having 7-17 carbon atoms and a polyfunctional monomer.

Provided herein are transdermal delivery devices comprising dextromethorphan. The transdermal delivery device can be characterized by the novel design, for example, with an adhesive layer and a reservoir layer, with an adhesive layer comprising a mixture of two adhesives, and/or with a skin permeation enhancer, e.g., in an amount that can significantly enhance the flux of dextromethorphan. The transdermal delivery device can also be characterized by its in vitro and/or in vivo release profile, for example, that can provide a desired pharmacokinetic profile described herein. Also provided herein are methods of administering dextromethorphan, and methods of treating a disease or disorder described herein, using the transdermal delivery device herein.

A method for suppressing a plasma concentration of an asenapine metabolite includes applying to a subject a patch comprising a support layer and an adhesive agent layer, the adhesive agent layer includes asenapine and/or a pharmaceutically acceptable salt thereof, and an adhesive base agent.

A method of delivering an active compound includes providing a delivery device having a first portion. The first portion defines a first outer surface of the device. An active compound is provided in the first portion. The first outer surface exhibits a first tack after providing the active compound and a second tack of at least 25 percent the first tack after delivering the active compound to the first outer surface.

The present disclosure relates to the to the transdermal administration of nabilone and cannabinoids and derivatives of these compounds, for the treatment and/or prevention and/or control of medical conditions.

The present invention relates to transdermal therapeutic systems (TTS) for the transdermal administration of asenapine comprising a self-adhesive layer structure containing a therapeutically effective amount of asenapine, such asenapine TTS for use in a method of treatment, processes of manufacture of such TTS as well as asenapine and transdermal therapeutic systems containing asenapine for use in a method of treatment and to a method of treating a human patient by transdermal administration of asenapine.

An organic-siloxane copolymer composition is useful for preparing a skin contact adhesive or a coating. A skin contact adhesive composition includes (I) an organic-siloxane copolymer composition and (II) an excipient. A skin contact adhesive prepared by hardening the composition is useful in applications such as adhesives for medical tapes, adhesives for wound dressings, adhesives for prosthetics, ostomy appliance adhesives, adhesives for medical monitoring appliances, adhesives for scar therapy treatments, adhesives for cosmetic patches, and transdermal drug delivery systems. A coating composition includes (a) the organic-siloxane copolymer composition and (b) a coating additive. The coating prepared by hardening the coating composition is useful for treating leather.

A crosslinkable composition is useful for preparing a skin contact adhesive or a coating on a substrate. The crosslinkable composition includes (A) a polyurethane-polyorganosiloxane copolymer and (B) a curing catalyst. The skin contact adhesive prepared by crosslinking the crosslinkable composition is useful in applications such as adhesives for medical tapes, adhesives for wound dressings, adhesives for prosthetics, ostomy appliance adhesives, adhesives for medical monitoring appliances, adhesives for scar therapy treatments, adhesives for cosmetic patches, and transdermal drug delivery systems.
