  • Patent number: 5008110
    Abstract: A shelf-stable device for transdermally administering an active pharmaceutical to a patient. The device includes a drug reservoir that contains the drug formulation. In one preferred embodiment of the present invention, the drug reservoir is sandwiched between an upper and a lower solvent barrier film that are made from a material such as a polyester that will not absorb the drug and/or skin permeating enhancing solvent, if any, contained within the reservoir. The drug reservoir and solvent barrier films are encapsulated within a hermetically-sealed compartment that protects the drug formulation from common environmental factors such as water vapor, oxygen, and light which can adversely affect the stability and efficacy of the drug formulation. The hermetically-sealed compartment also prevents the drug formulation from coming into contact with and possibly dissolving the adhesive used to secure the device to the patients's skin.

  • Patent number: 5006004
    Abstract: A dispenser for the topical application of a liquid product. In a preferred embodiment of the present invention, the dispenser comprises a compressible reservoir, a feed tube, a smooth, substantially non-porous applicator tip, and a tip cover. Compression of the reservoir causes liquid product to flow onto the exposed surface of the applicator tip and form an encapsulating sheet of the liquid product. The liquid product may then be transferred from the applicator tip to the surface to be treated by contacting the surface with the liquid product coated applicator tip.

  • Patent number: 5006394
    Abstract: A polymeric multilayer film structure having a high percentage of fillers is disclosed. The fillers are concentrated in a separate filler containing layer having about 5 to about 20 percent of the thickness of the total multilayer film. The filler containing layer is coextruded with a base layer comprising the balance of the thickness of the multilayer film. By keeping the filler containing layer thin, relative to the total film thickness, a multilayer film having a filler concentration up to about 60 weight percent is achievable without significantly adversely affecting the material properties of the multilayer film structure.
