  • Skin friendly active substance patch for transdermal administration of hyperemic active substances
    Patent number: 7001613
    Abstract: An active substance matrix patch for controlled delivery of at least one hyperemic active substance to the skin, comprising a flexible cover layer and a water insoluble, pressure sensitive adhesive active substance matrix, wherein said adhesive matrix is free from mineral oils and tackifier resins and comprising: a) from 25 to 90% by weight of synthetic framework polymers based on polyisobutylene, b) from 5 to 40% by weight of amorphous poly-?-olefin, c) from 10 to 60% by weight of an insoluble hydrophilic filler having an average particle size of less than 100 ?m, and d) from 0.001 to 20% by weight of the hyperemic active substance.

  • Multilayer backing construction for active substance patch systems
    Publication number: 20040091521
    Abstract: An active substance patch comprising a laminate coated on its skin-facing side with an adhesive comprising an active substance. In one embodiment, the laminate has at least two layers. More particularly, in this embodiment, the side of the laminate remote from the skin includes a barrier layer that is impermeable to the active substance, and the skin-facing side of the laminate includes a backing layer. These two layers are preferably configured so that they can be separated from one another by a user.
