Various embodiments of a drug delivery device and a method of using such device are disclosed. The drug delivery device includes a backing layer having a first major surface and a second major surface, and an array of patch segments defined by segment separation lines disposed in the backing layer. Each segment separation line is adapted to enhance separation of one or more patch segments from the array of patch segments. Further, a patch segment of the array of patch segments includes a polygonal shape.

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

The present invention is directed to therapeutic pharmaceutical compositions of 1-Methyl-2′, 6′-pipecoloxylidide or it pharmaceutically acceptable salts for application to the skin and the use thereof.

A benefit agent delivery system whereby benefit agents can be delivered on demand and/or a variety of different benefit agents at different concentrations can be delivered from the same system. The benefit agent delivery system includes a microcell layer comprising a plurality of microcells, wherein the microcells are filled with a carrier and a benefit agent. The microcells include an opening, wherein the opening is spanned by a sealing layer comprising a polymer and metallic material. Application of an electric field across the microcell layer and the sealing layer results in the migration of the metallic material from the sealing layer and the creation of a porous sealing layer, allowing the benefit agent to be released from the benefit agent delivery system.

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.

A pad for electrically stimulated wound healing, including a pad configured to be placed on a wound, at least one anode disposed on the pad to contact the wound, and at least one cathode disposed on the pad to contact the wound, the at least one cathode being disposed separately from the at least on anode. The pad wherein the at least one anode and the at least one cathode in contact with the wound provide a flow of electrical current in an intended direction through the wound based on the separate locations of the at least one anode and the at least one cathode.

A opioid taper regimen, and its method of manufacture, for use in a method of opioid reduction leading to abstinence. Said regimen is administered within the range of 2 to 4 years, or more. The regimen comprises novel approaches to common problems encountered during tapers of low dose opioid addiction. The reduction regimen is generally linear; reduces the dosage level once per week; doses every six hours; reduces doses by steps in the range of about 0.001 to 0.0500 mg; has, near the end, ten weeks of doses of about 0.0025 mg buprenorphine q.i.d.; followed by four or more weeks of placebos. Instructions for manufacture of doses that differ by 0.0025 mg and 0.0050 mg buprenorphine are specified.

A transdermal device (1) comprising at least one substrate (2) arranged to be applied against the dermal surface or the mucous membrane. The at least one active ingredient is grafted to the substrate (2) by at least one photolabile ligand, and at least one light source (11) operated by a control mechanism arranged to generate light pulses, of a predetermined wavelength, intended to break covalent bonds between the active ingredient and the ligand in order to release the active ingredient from the substrate (2). The substrate (2) comprises at least one porous matrix (6) with a three-dimensional structure comprising a plurality of pits (7) organized in a sponge-like fashion and constructed of a polymer chosen between chitin and chitosan, and the matrix (6) defines at least one three-dimensional tank (8). The active ingredient is contained and grafted by the ligand.

The present invention relates to a drug delivery fabric having a drug-containing layer, wherein the drug delivery fabric comprises a surface layer, a middle layer, and a drug-containing layer, the middle layer is formed of a yarn having hydrophilicity relatively equal to or higher than that of the surface layer, the drug-containing layer is formed of a cellulose derivative film containing a drug.

Dosing regimen for transdermal delivery of hormones comprising a 28 day treatment cycle with a fixed treatment interval and a fixed rest interval.
