  • Publication number: 20230248661
    Abstract: 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. The inner phase forms dispersed deposits in the outer phase. The inventive transdermal therapeutic systems optionally include a skin contact layer.

  • Patent number: 11633367
    Abstract: A transdermal therapeutic system containing rotigotine base in a self-adhesive layer structure. The system includes a backing layer, and a rotigotine-containing biphasic layer. The biphasic layer has an outer phase having a composition including 75% to 100% of a polymer or a polymer mixture, and an inner phase that forms dispersed deposits in the outer phase. The inner phase includes rotigotine base and a polymer mixture of at least two hydrophilic polymers. The hydrophilic polymers are selected from the group of polyvinylpyrrolidones having a K-Value of at least 80, polyvinylpyrrolidones having a K-Value of less than 80, 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. The polymer mixture in the inner phase is present in an amount sufficient so that it forms a solid solution with the rotigotine base.
