Abstract:
A Rotigotine-containing composition having a matrix mixture system formed from a polyvinylpyrrolidone and a combination of an acrylic pressure-sensitive adhesive with a silicone pressure-sensitive adhesive. The polyvinylpyrrolidone may be present in an amount of about 1-10% by weight in matrix mixture system. The acrylic pressure-sensitive adhesive may be present in an amount of about 1-25% by weight in the matrix mixture system. The silicone pressure-sensitive adhesive may be present in an amount of about 65-98% by weight in the matrix mixture system. The composition further includes 1-40% of Rotigotine on the basis of the total weight of the composition. The composition provides improved properties in the solubility, release and initial penetration level of Rotigotine. Also disclosed is a transdermal patch that includes the Rotigotine-containing composition, as well as methods of manufacturing and using the Rotigotine-containing composition.
