Transdermal device for administering testosterone or one of the derivatives thereof

A self-adhesive transdermal device for administering testosterone and/or at least one derivative thereof, which comprises, successively, at least, one support layer, one self-adhesive matrix layer and one detachable protective layer, said adhesive matrix layer comprising, relative to the total weight of the matrix layer:

• a) 40% to 80% by weight of at least one self-adhesive polymer selected from acrylic polymers, with an acid number of between 10 and 70, with an acid functionality and a glass transition temperature of between −70° C. and −20° C.;
• b) 5% to 25% by weight of at least one formulation adjuvant for the matrix layer selected from polymers with a number-average molecular mass of between 2 500 and 3 000 000;
• c) 5% to 20% by weight of at least one solvent selected from the group consisting of solvents for testosterone and derivatives thereof, in which the solubility of the testosterone or derivative thereof is between 5% and 20% m/m;
• d) 2% to 10% by weight of testosterone and/or at least one derivative thereof, as a supersaturated solution, and wherein the matrix layer does not comprise a permeation promoter of testosterone.
