  • Patent number: 10010511
    Abstract: A transdermal drug delivery system is provided that includes a drug-in-adhesive matrix layer and a backing layer. The matrix layer includes an active pharmaceutical ingredient, a cross-linked polyvinylpyrrolidone binder, a mesoporous silicon dioxide filler, and a pressure sensitive adhesive, while the backing layer forms an exterior facing-surface of the delivery system. The ratio of the mesoporous silicon dioxide filler to the cross-linked polyvinylpyrrolidone binder ranges from about 1:1 to about 1:8. As a result of the specific components of the matrix layer and the amounts in which they are utilized, the resulting delivery system, which can include a homogeneous dispersion of the active pharmaceutical ingredient in the formulation, is capable of delivering the active pharmaceutical ingredient over a period of up to about 7 days in a generally constant and controlled fashion. Further, the only layer that contemplates the use of an adhesive component is the drug-in-adhesive matrix layer.

  • Patent number: 8852628
    Abstract: Disclosed is a transdermal composition for delivery of diclofenac comprising the use of a pharmaceutically acceptable acid or salt form in an admixture with a pharmaceutically acceptable adhesive matrix carrier. In a preferred embodiment, diclofenac is present as the free acid and potassium salt form in the adhesive matrix composition together with a dual permeation enhancer. The adhesive matrix composition is applied in a method of substantially increasing drug delivery for 24 or more hours.

  • Patent number: 8337884
    Abstract: A transdermal composition is disclosed which contains a blend of one or more polymers, one or more drugs, at least one of which has a low molecular weight and is liquid at or about room temperatures. The composition is substantially free of water and liquids which have a normal boiling point (a) optionally below processing temperatures and (b) greater than or equal to the temperature of the low molecular weight drugs. The composition does not suffer from the substantial loss of the lower molecular weight drug during production of the transdermal system. A transdermal composition is also disclosed which has one or more drugs, at least one of which has a low molecular weight and is liquid at or about room temperatures, and a polymer matrix including one or more high shear resistant polymers. The high shear resistant polymer(s) reduce the plasticizing effect of the low molecular weight drug, and has sufficient tack and shear for application to a human being.

  • Patent number: 8153151
    Abstract: Compositions and methods for controlling transdermal drug delivery, particularly of amine-functional and basic drugs, comprising a blend of a first silicone-based polymer having a reduced silanol concentration and a second silicone-based polymer have a substantial or high silanol concentration. The blend of such silicone-based polymers, particularly pressure-sensitive silicone adhesives, provides sufficient drug solubility and reduced initial drug delivery onset to permit a prolonged delivery duration at a substantially zero-order rate of delivery.

  • Patent number: 8110565
    Abstract: A composition for transdermal administration resulting from an admixture includes: a therapeutically effective amount of a drug that includes a parent drug and a prodrug; and a pharmaceutically acceptable carrier, wherein the parent drug and prodrug are individually present in an amount sufficient for a pharmacological effect. In a preferred embodiment, the admixture includes: a therapeutically effective amount of a pharmaceutically active agent that includes a corresponding steroid and a steroid derivative; and a carrier for the pharmaceutically active agent. The steroid and the corresponding steroid derivative are present in a weight ratio of 10:1 to 1:10 steroid:corresponding steroid derivative. In a preferred embodiment ratio is 6:1 to 1:6. In a preferred embodiment, the corresponding steroid derivative is a steroid ester. In another preferred embodiment, the carrier is a polymer that includes a pressure-sensitive adhesive.
