Definitions

  • Non-rinsed chemical foam containing trifarotene and its use in the treatment of ichthyosis
  • the present invention relates to a topical product not rinsed in the form of a foam for the pharmaceutical or cosmetic treatment of the skin comprising trifarotene.
  • Trifarotene is a new retinoid and corresponds to 3 "-tert-butyl-4 '- (2-hydroxyethoxy) -4" -pyrrolidin-1-yl [1,1', 3 ', 1 "] terphenyl-
  • the present invention also relates to the use of the product according to the invention for the treatment of ichthyosis.
  • compositions for a more practical and fast topical application.
  • Foams help to overcome tolerance problems through better dose control, thanks to their spreading properties and low density.
  • Ichthyosis is the result of a thickening of the stratum corneum of the epidermis. They are due to the insufficient removal of the stratum corneum, or to an acceleration of the formation of the epidermis (superficial layer of the skin), and of the stratum corneum (superficial layer of the epidermis).
  • creams and ointments are indispensable in ichthyosis. These local treatments aim to reduce the dander and improve skin comfort and the appearance of the skin. These treatments include simple moisturizing creams and / or creams in which are added agents that will better detach the dander and that is called keratolytics. In all cases the treatments must bring a lot of emollience to soften the skin.
  • certain compounds used in the compositions intended for a known topical application may cause side effects which may limit their use and therefore their effectiveness.
  • some actives have the major disadvantage of inducing irritation that may result in poor tolerance of the product. This can thus create on the part of the patient a behavior of non-observance of the treatment and the discontent with regard to said treatment.
  • There is therefore a need to develop new galenic forms overcoming the aforementioned drawbacks in terms of tolerance, efficiency and compliance.
  • new galenic forms and in particular foams or foaming compositions for better dose control and in which trifarotene is stable, well tolerated, effective and pleasant to apply.
  • composition according to the invention has the advantage of being in the form of a foam generated extemporaneously, and very well tolerated.
  • composition according to the invention is not removed by rinsing.
  • composition is particularly well tolerated, even though it is not rinsed off, as shown in the examples illustrating one of the methods of assessing tolerance presented hereinafter.
  • composition also has the advantage of remaining on the surface of the skin (stratum corneum and epidermis essentially), in order to avoid undesirable effects such as irritation and to obtain a foam adapted to the treatment of ichthyosis .
  • the effectiveness of an active ingredient is related to the release and kinetics of penetration of the active through the skin.
  • the form composition plays its essential role of vehicle of the active ingredient so that it reaches its therapeutic target.
  • the release-permeation test described in Example 5 on ex-vivo human skin highlights the advantage of applying a chemical foam containing trifarotene.
  • the formulations of the invention make it possible to obtain a composition in the form of a mousse making it possible to reduce the undesirable effects and in particular the irritation, in particular on young skin.
  • the surface of the skin is also the seat of the keratolytic action of trifarotene for the treatment of ichthyosis.
  • foams or foaming compositions on the market. However, they all have a number of disadvantages:
  • Aerosols in which the foam is generated by a propellant gas but with the disadvantage of being aerosols with the risks well known to them (pollution, respiratory risks in particular).
  • Foaming formulas containing foaming surfactants generally causing irritation problems from the detergent properties of these foaming surfactants.
  • compositions for topical application containing trifarotene in well-tolerated compositions for application topically in humans particularly a non-rinsed application (i.e., the composition is not rinsed off after application).
  • the object of the present invention is therefore to provide a composition that meets these needs.
  • Foaming surfactants are defined as surfactants which produce a voluminous, stable and unctuous foam when they are mixed with water according to tests well known to those skilled in the art. Foaming surfactants include anionic surfactants, cationic surfactants, amphoteric surfactants and nonionic surfactants of the alkylpolyglucoside and glucamide family.
  • the pharmaceutical form according to the invention has the advantage of guaranteeing good stability of trifarotene.
  • this formulation advantageously leads to the production of a soft, perfectly tolerated and non-irritating foam, which allows a better coverage of the area to be treated. treat and overcomes tolerance problems through better dose control, thanks to the spreading properties and low density of the foam.
  • this dosage form does not require for its implementation the use of propellants or aerosols.
