Multi-Day Patch for the Transdermal Administration of Rotigotine

The present invention relates to a transdermal therapeutic system formed from (a) a backing layer, (b) a solvent-based self-adhesive matrix layer containing rotigotine as active ingredient, and (c) a release liner, in which the self-adhesive matrix layer has a coating weight of about 75-400 g/m.sup.2 and comprises a reservoir layer containing about 9-25 wt.-% rotigotine based on the weight of the reservoir layer; a kit containing two transdermal therapeutic systems of the present invention; and methods for the preparation of the transdermal therapeutic system of the present invention. The present invention further relates to methods of treatment based upon the application of the inventive transdermal therapeutic systems once or twice weekly via systems adapted to allow for the transdermal administration of therapeutically effective amounts of rotigotine for at least 3 days.

TRIPTAN MICROPORATION DELIVERY SYSTEM

A transdermal delivery system for delivery of a triptan into a tissue membrane of a subject. The system includes a transdermal microporation apparatus for heating a skin surface and a triptan drug delivery patch. The drug delivery patch comprises a top layer comprising an adhesive, a middle layer comprising the triptan, and a bottom layer. A method for treating a subject comprises identifying a subject having a migraine, using the transdermal microporation apparatus to open a plurality of micropores in the skin of the subject, and applying the triptan drug delivery patch to the subject's skin over the micropores for a period of time effective to deliver the triptan through the micropores in an amount effective to treat the subject's migraine.

Topical copper ion treatments and methods of making topical copper ion treatments for use in various anatomical areas of the body

A topical copper ion treatment in basic form comprises a copper ion-containing solution composed of a biocompatible solution containing copper ions obtained by leaching of the copper ions from copper metal into the solution. The copper ion-containing solution can be combined with various carriers to form various forms of the copper ion treatment including creams, gels, lotions, foams, pastes, tampons, solutions, suppositories, body wipes, wound dressings, skin patches, and suture material. A method of making the copper ion-containing solution involves placing solid copper metal in a quantity of a biocompatible solution and maintaining the solution at a specified temperature for a predetermined period of time during which copper ions leach from the copper metal into the solution, and thereafter separating the solution from the solid copper metal.

Transdermal Delivery System Containing Rotigotine

The present invention relates to transdermal therapeutic systems for the transdermal administration of rotigotine containing a therapeutically effective amount of rotigotine base in a self-adhesive layer structure that includes a backing layer and a rotigotine-containing biphasic layer. The biphasic layer has an outer phase formed from a polymer or a polymer mixture along with an inner phase that includes rotigotine base and a polymer mixture including polyvinylpyrrolidone having a K-Value of at least 80 and at least one further hydrophilic polymer selected from the polymer groups: copolymers of vinyl caprolactam, vinylacetate and ethylene glycol, copolymers of vinylpyrrolidone and vinylacetate, copolymers of ethylene and vinylacetate, polyethylene glycols, polypropylene glycols, acrylic polymers, and modified celluloses.
