Abstract:
A composition for topical application characterized in that it includes, in a hydrogel base, vanillyl butyl ether and menthol. The composition described herein produces an ordered development of cold and warm sensations, obtaining effects that are particularly useful in the treatment of painful disorders of neurological and/ or muscular origin. The composition has further moisturizing and soothing effects that concur to an effect that is also curative, i.e., not simply symptomatic, of rheumatic and muscular pain, trauma and bruises. The composition is compatible with each administration form, being preferably and advantageously formulated as a plaster.
Abstract:
Provided herein is a system and method for facilitating removal of a drape from a tissue site. One aspect provides a system comprising a drape, and adhesive layer, and a release agent, where the system is adapted to be coupled to a tissue site and released therefrom upon or after exposure to an external stimulus. Another aspect provides a method for application and removal of a drape using less force than required with a conventional drape.
Abstract:
A transdermal drug-containing dosage unit comprises: a backing layer substantially impervious to the drug to be delivered transdermally; a first polymeric adhesive matrix, in contact with the backing layer, having dispersed therein the drug and having a first delivery profile of the drug; a second polymeric adhesive matrix, in contact with said first polymeric adhesive matrix, having dispersed therein the drug and having a second delivery profile of the drug, wherein said second delivery profile is different from said first delivery profile; and a release liner in contact with the second polymeric adhesive matrix. The first polymeric adhesive matrix can release the drug more quickly or more slowly than the second polymeric adhesive matrix. Through the selection of the two matrices, the delivery profile of the drug through the skin can be selectively modified and controlled.
Abstract:
A polymerized microemulsion pressure sensitive adhesive composition is described. The composition has peel adhesion of at least 3 Newtons/100 mm as measured according to a PSTC-1 Test. The composition preferably has a bicontinuous structure of a continuous phase of a hydrophobic pressure sensitive adhesive polymer and a continuous phase of a hydrophilic polymer. The bulk properties of both polymers are retained in the bicontinuous structure. The composition is prepared from a microemulsion comprising a free-radically ethylenically unsaturated polar amphiphilic or hydrophilic monomer or oligomer in the aqueous phase, a free-radically ethylenically unsaturated hydrophobic monomer, having a glass transition temperature suitable for forming a pressure sensitive adhesive, in the oil phase, water, and surfactant. Uses for the pressure sensitive adhesive composition include biomedical articles, such as biomedical electrodes, medical skin coverings, and pharmaceutical delivery devices, and industrial articles, such as zinc/adhesive tapes used for cathodic protection of rebars embedded in concrete.
Abstract:
A medical dressing (30) is disclosed, comprising an adhesive layer (3) having skin-facing surface (6) to adhere the medical dressing to a dermal surface, wherein said adhesive layer comprises a first chemical compound incorporated within said adhesive layer, and wherein at least a portion of said skin- facing surface comprises a coating (9) comprising second chemical compound. Also disclosed is a method of manufacturing such a medical dressing.
Abstract:
Methods and compositions for securing to and removing adhesive tapes from substrates, e.g., delicate substrates such as skin, are described. The methods include providing an adhesive tape comprising an adhesive layer and a support layer in contact with the adhesive layer. A first adhesion level between the adhesive layer and the support layer is, or can be controlled to be, less than a second adhesion level between the adhesive layer and the substrate. The methods further include applying the adhesive tape to the substrate by contacting the adhesive layer to the substrate while the support layer remains in contact with the adhesive layer; and removing the support layer from the substrate by separating the support layer from the adhesive layer.
Abstract:
A patch for cutaneous application to the external surface of an elongated member of a human body for purposes of cleansing or for tactile stimulation and/or delivery of a transdermal pharmaceutical agent during sexual activity, has an underside having at least a portion thereof coated with a human skin compatible adhesive, for application to the skin of an elongated member of a human body. The patch has a dimension of length which is greater than its dimension of width, and has an outer surface which is distal from the skin when applied to a finger of a human hand or to a human male penis. The outer surface of the patch may be a textured surface or a smooth surface. At least one transdermal agent may be applied to the underside of the patch, and is typically an erectogenic agent.

Abstract:
A protective device (10) having a substantially rigid casing (11) for placement on a patient's skin, wherein the casing has a hollow interior facing the patient's skin and a lip (16). The casing (11) can be spanned across its hollow interior by a membrane (14). The casing can have a first adhesive seal (15) attached to a bottom surface of the lip of the casing (16), and a second adhesive seal (12) attached to the top surface of the lip of the casing (16).
Abstract:
A wound dressing is provided that serves unique dual-purpose role. One surface of the dressing is comprised of a polyurethane foam (20) and the other surface is comprised of a non-adherent thin-film (30) of polydimethylsiloxane and polytetrafluoroethylene interpenetrating polymer networks ("IPN"). With the foam side of the dressing down against the wound, the product provides an adhesive surface for difficult fixation conditions. With the IPN side of the dressing against the wound, the dressing provides non-adherent covering for fragile and sensitive wounds.
