Definitions
- the present invention generally relates to devices for cutaneous application.
- the invention more particularly relates to products and methods for better skin fixation of devices such as patches or transdermal patches, intended to interact with the skin to moisturize or facilitate the absorption of cutaneous biologically active substances. It also relates to a method for the manufacture of such devices, as well as their uses, in the therapeutic, diagnostic and / or cosmetic field, for example.
- Cutaneous or percutaneous absorption is the transfer of a substance through the skin, typically from the outside to the blood. This absorption is generally defined as the sum of two phenomena: a penetration of the molecules into the layers of the skin, followed by resorption by the blood or lymphatic circulation from the papillary dermis and then the deep dermis.
- the penetration stage is physically a passive diffusion through each or some of the structures of the integument: the stratum corneum, the Malpighi epidermis, the dermis and the cutaneous appendages.
- Penetration in the broadest sense, does not necessarily imply a diffusion through all the structures of the integument, especially the deep ones, but it must preferably allow an exposure of the substance to the immune or circulatory system. Once absorbed, the substance is usually distributed in the body and then, after being metabolized, it is eliminated. The steps following percutaneous absorption are normally similar to those encountered for any other route of administration.
- the stratum corneum is the most effective barrier against the penetration of a substance: anatomically, the substance can penetrate in two ways: one through the intercellular spaces of the stratum corneum and through the horn cells themselves, other through the skin appendages. It has been mentioned that the passage of hydrophilic active principles into the stratum corneum is facilitated when these compounds are find in a humid atmosphere.
- the substance antigen, immunogen, adjuvant, etc.
- the substance is able to meet the immunologically competent cells and, in particular, the antigen-presenting cells such as the cells. of Langerhans whose role is essential in the immunological reaction of the body.
- patches are “adhesive”, that is to say that they are provided with a glue or an adhesive, typically acrylic type, ensuring the narrow maintenance of the patch on the skin.
- the document US2004 / 137004 relates to a transdermal patch that can comprise different formulations and an acrylic adhesive or in the form of a hydrogel.
- US2006 / 002949 relates to an unadjuvanted transcutaneous immunization method in which an antigen in powder form can be used.
- US2006 / 147509 relates to a device for transdermal delivery of an immunogen, comprising a saponin-sterol delivery system and an occlusive vehicle.
- WO00 / 43058 relates to a method of transdermal administration of active ingredient in the form of accelerated particles. The method uses either an injection with the PowderJect TM device or a patch held in place by an athletic band.
- WO02 / 07325 relates to a patch for transcutaneous immunization and the document
- WO2006 / 007366 relates to fusion proteins for transcutaneous immunization.
- the antigen may be used in the form of powder or liquid, alone or mixed with an adjuvant.
- an adhesive can be used to maintain the patch, it is either a resin or an aqueous adhesive.
- Patches are also known for moisturizing the skin.
- the patch does not necessarily contain active substance, but its application, in particular of occlusive format, creates a zone of hydration in contact with the skin.
- patches are mainly intended for the field of cosmetics.
- Patches of the prior art have disadvantages, particularly when the desired effect requires a strong adhesion of the patch, obtained by a conventional adhesive (acrylic for example).
- a conventional adhesive acrylic for example.
- the separation between the adhesive surface and the skin can indeed lead to irritation and a sensation of pain.
- the use of aqueous adhesives can lead to an alteration of the active ingredient on the patch and therefore a short shelf life.
- a compromise must therefore be found for the adhesive strength of the adhesive surface, in order to limit the sensation of pain during the withdrawal, while ensuring that the patch remains on the skin. This membership is relatively difficult to establish precisely because it can vary with the duration of storage of the patch before its application.
- the invention aims to solve one or more of these disadvantages.
- the invention indeed provides a hydrophilic adhesive patch for cutaneous application, characterized in that the adhesion of the patch to the skin is provided by a hydrophilic powder acquiring adhesion in the presence of water.
