A transdermal drug delivery composition comprises an acrylate copolymer and from about 8% to about 30% by weight fentanyl. A transdermal fentanyl delivery composition comprising methyl laurate or tetraglycol as a permeation enhancer is also provided. The transdermal drug delivery compositions can be used to make a transdermal drug delivery device for the delivery of fentanyl.

A multi-layer transdermal drug delivery system containing ibuprofen or a structural analogue thereof, comprising a transdermal patch containing ibuprofen or a structural analogue thereof and a second combined layer. The transdermal patch comprises a polymer matrix layer, the polymer matrix layer comprising an active ingredient, a compound containing at least one amino group, and a pressure-sensitive adhesive. All or some of active ingredient-amino compound salts or all or some of free active ingredients formed in the polymer matrix layer are kept in a uniform dissolution state in the polymer matrix, and can be stably stored before use, without recrystalization. The transdermal drug delivery system can continuously and controllably deliver a therapeutically effective amount of ibuprofen or a structural analogue thereof for 12 to 24 hours in the absence of a transdermal enhancer, has excellent wearing ability, and avoids a cold flow phenomenon.

The present invention relates to a transdermal device including porous microparticles capable of containing an active principle, in particular nicotine, and to the use thereof as a drug, in particular for tobacco cessation. The present invention further relates to a method for preparing a transdermal device including porous microparticles filled with an active principle.

Methods, compositions, and devices for transdermally administering an active agent such as memantine are provided.

Pharmaceutical formulations of novel indole compounds and psilocybin analogs are manufactured, provided in novel oral, transdermal, and nasal pharmaceutical compositions for use to treat neurological, mood or abuse diseases and disorders.

The present disclosure relates to the to the transdermal administration of THC and/or CBD and derivatives of these compounds, for the treatment and/or prevention and/or control of multiple sclerosis, multiple sclerosis-related muscle spasms, and pain and/or spasticity in multiple sclerosis.

The invention provides compositions and methods for delivering vitamin D to a human subject. In one embodiment the invention provides a transdermal patch for the transdermal administration of vitamin D comprising: (a) a backing layer that serves as the outer surface of the patch during use; (b) an adhesive drug reservoir layer for affixing the patch to human skin; and (c) a release liner, which upon removal exposes the adhesive drug reservoir layer. The adhesive drug reservoir layer can include vitamin D, a polymeric adhesive, an organic solvent, and a permeation enhancer.

The present invention relates to transdermal drug delivery system of pharmaceutical compositions, which have a satisfactory in-vitro performance and good bioavailability. In particular, the transdermal pharmaceutical composition of clobazam in the present invention includes a micro-emulsion in liquid or semi solid form, in a dosage form adapted for transdermal delivery (e.g., transdermal patch) for treatment of certain types of epilepsy and anxiety for continues application.

The invention relates to a silyl-containing polymer that is used, together with a tackifying resin to form an adhesive composition capable of storing and delivering drugs to the skin of a user. Typically the composition is formed into a patch which shows excellent adhesion to the skin even when drugs and other additives are dissolved into the composition.

It is an object of the present invention to provide a novel patch for alleviating or treating the symptoms of neurodegenerative disease. According to the present invention, provided is a patch for alleviating or treating the symptoms of neurodegenerative disease, comprising a scopolamine salt and/or a hydrate thereof, wherein the application time of the patch per application is within 48 hours.
