A method and a non-rate controlled, monolithic, subsaturated patch for transdermally administering fentanyl and analogs thereof, for analgetic purposes, to a subject through skin over an extended period of time are disclosed.

Among other things, the present disclosure provides compositions and methods for an elastomeric cross-linked polyester material. Such an elastomeric cross-linked polyester material, in some embodiments, comprises a plurality of polymeric units of the general formula (-A-B—).sub.p, wherein p is an integer greater than 1; and a plurality of urethane cross-links each of which covalently links two polymeric units to one another, which two linked polymeric unit each had at least one free hydroxyl or amino group prior to formation of the crosslink.

Described are transdermal drug delivery systems for the transdermal administration of tertiary amine drugs, such as rivastigmine, fentanyl or rotigotine, comprising a polymer matrix comprising a free base form of the drug and at least one carboxyl group-containing compound. In some embodiments, the systems include a rate-controlling membrane and a skin-contacting face adhesive apart from the polymer matrix.

The present invention relates to a transdermal delivery system (TDS) comprising at least one dopamine agonist, wherein the at least one dopamine agonist is present in a matrix containing at least one polymer from the class of polybutylene. The present invention also relates to a method for producing the TDS according to the invention and to the use of the TDS according to the invention.

The present invention relates to transdermal therapeutic systems (TTS) for the transdermal administration of solifenacin.

Compositions comprising polymeric networks comprising combinations of small molecule hair growth agents and natural products (e.g., vesicles, such as stem cell-derived exosomes) are described. The polymeric network can, for example, comprise keratin crosslinked via intermolecular disulfide bonds. Alternatively, the polymeric network can comprise keratin or a derivative thereof and another crosslinked hydrophilic polymer. Microneedles, microneedle arrays, and skin patches comprising the compositions are also described, as are methods of treating hair loss and/or promoting hair growth using the microneedles, microneedle arrays and/or skin patches.

The present invention concerns a transdermal delivery system (TDS) comprising at least one active ingredient, wherein the active ingredient is in a non-aqueous matrix, and wherein the non-aqueous matrix has a reduced moisture content. Furthermore, the present invention concerns a method for the production of the TDS in accordance with the invention, as well as the use of the TDS in accordance with the invention.

A system that transdermally delivers a drug to a patient can be used to reduce suffering from acute/chronical musculoskeletal pain. The system includes a backing layer, an adhesive layer, a topical applicator, a suitable quantity of drug, and a quantity of topical carrier. The topical applicator is connected across and against the backing layer by the adhesive layer. The suitable quantity of drug and the quantity of topical carrier are homogenously mixed together as a topical medication, which is retained and dispensed from the topical applicator. The topical applicator includes a flat applicator body, a plurality of blunted spikes, and a containment rim. The flat applicator body is the structural base of the topical applicator. The containment rim is used to perimetrically confine the topical medication. The blunted spikes are used to increase the surface area of the topical applicator in order to improve its retention of the topical medication.

A transdermal dosing unit may include a first segment having a first pharmaceutical in a first reservoir, a first releasing compound, and a first adhesive component, a second segment removably connected to the first segment, the second segment having a second pharmaceutical in a second reservoir, a second releasing component, and a second adhesive component, and a backing component. The transdermal dosing unit may further include additional segments, and may include a perforated section between each segment. The first adhesive component may have a first adhesion strength, and the second adhesive component may have a second adhesion strength that is either different from or approximately equal to the first adhesion strength. A method of titrating a dose of such a transdermal dosing unit may include applying the transdermal dosing unit to a subject, and removing the first segment while leaving the second segment on the subject.

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