A modular transdermal drug delivery system is provided, the system including: an upper module in which an outer backing layer is laminated to a pressure-sensitive adhesive layer that is covered by a removable release liner prior to assembly; and a lower module with a porous drug reservoir layer laminated to a skin-contact adhesive that affixes the system to the skin during drug delivery, where the skin-contact adhesive is, in one embodiment, an adhesive layer that is substantially co-extensive with the porous drug reservoir layer and, prior to use, protected with a second removable release liner. Methods of manufacture and use are also provided, as is an assembled transdermal drug delivery system fabricated by affixing the pressure-sensitive adhesive layer of the upper module to the porous drug reservoir layer of the lower module.

The invention relates to a method for manufacturing a transdermal patch from a drug-containing web that minimizes waste. The web is a layered composite that includes at least a backing layer and a drug-in-adhesive layer and a first strippable release liner. The web is kiss-cut along intersecting cut lines at least down to the depth of the liner, generally defining the extent of individual transdermal patches. The intersections of the cut lines define small zones that are punched out of the web in a generally star shape. The portions of the web above the liner are peeled away from the liner and transferred to a faster moving second liner so that the patches are now further spaced apart from one another. This second liner is then cut to provide transdermal patches that are mounted to release liners that are substantially broader in extent than the patches themselves.

The disclosure provides dermal patch formulations that include a pharmaceutically active agent, such as one or more cannabinoids. The formulations can include dihydromyricetin for the purpose of increasing the flux of the pharmaceutical agent into human skin.

A method for manufacturing a steel sheet having a yield strength YS of more than 1000 MPa, a tensile strength TS of more than 1150 MPa and a total elongation E of more than 8%, includes the steps ofpreparing a steel sheet through rolling from a steel containing in percent by weight 0.19% to 0.22% C, 2% to 2.6% Mn, 1.45% to 1.55% Si, 0.15% to 0.4% Cr, less than 0.020% P, less than 0.05% S, less than 0.08% N, 0.015% to 0.070% Al, the reminder being Fe and unavoidable impurities; and soaking the sheet at an annealing temperature TA between 860 C. and 890 C. for a time between 100 s and 210 s, cooling the sheet to a quenching temperature QT between 220 C. and 330 C., from a temperature TC not less than 500 C. at a cooling speed not less than 15 C./s, heating the steel sheet during a time between 115 s and 240 s up to a first overaging temperature TOA1 higher than 380 C., then heating the sheet during a time between 300 s and 610 s up to a second overaging temperature TOA2 between 420 and 450 C., cooling the steel sheet to a temperature less than 100 C. at a cooling speed less than 5 C./s. The structure of the steel contains more than 80% of tempered martensite, more than 5% of retained austenite, less than 5% of ferrite, less than 5% of bainite and less than 6% of fresh martensite.

A device for wound care, related method of manufacturing and uses are provided. The device 100 comprises a base layer 10, a functional layer 20 supported on the base layer and containing at least one chemical substance 21 suitable for wound care and a coating film 22 laid over said functional layer and having a skin-contact surface 22A. The coating film 22 is configured, upon being contacted with skin, to dissolve and to release said chemical substance 21 to skin through the skin-contact surface 22A. The coating film 22 is preferably an atomic layer deposition (ALD) film.

The present invention concerns a method for the production of a transdermal delivery system (TDS) comprising at least one active ingredient, wherein the method comprises temperature-conditioning. Furthermore, the present invention concerns a TDS which can be produced by means of the method in accordance with the invention, as well as the use of the TDS in accordance with the invention.

The present invention relates to a device for the manufacture of pharmaceutical patches, a method for the manufacture of pharmaceutical patches, and a package comprising a pharmaceutical patch obtainable by said method.

A modular transdermal drug delivery system is provided, the system including: an upper module in which an outer backing layer is laminated to a pressure-sensitive adhesive layer that is covered by a removable release liner prior to assembly; and a lower module with a porous drug reservoir layer laminated to a skin-contact adhesive that affixes the system to the skin during drug delivery, where the skin-contact adhesive is, in one embodiment, an adhesive layer that is substantially co-extensive with the porous drug reservoir layer and, prior to use, protected with a second removable release liner. Methods of manufacture and use are also provided, as is an assembled transdermal drug delivery system fabricated by affixing the pressure-sensitive adhesive layer of the upper module to the porous drug reservoir layer of the lower module.

A portable transdermal administration patch apparatus comprises a communication control device and a pharmaceutical device which is fixed to and arranged at a lower end of the communication control device and electrically connected to the communication control device. The communication control device is formed of a micro-battery, a wireless control device and a micro-controller which are electrically connected. The preparation of the patch apparatus is achieved by: the preparation of medicinal patches and non-medicinal patches, the mounting of electrodes, interfacing with a micro-controller, and the communication control system, and starting administration. The transdermal apparatus is wearable and can be remotely controlled, and is convenient for administration, in particular, for the situations of daily administration for elderly patients with chronic illness and when there are a larger number of admitted inpatients, where a nurse can pre-set the administration time and dose, thus saving time and efforts of medical staff.
