Abstract: Rapid-disintegration monolayer film for the oral administration of active substances, comprising a water-soluble support containing at least one active substance, characterized in that it comprises a polymeric mixture of a hydrophilic film-forming agent formed from a copolymer of polyvinyl alcohol and of polyethylene glycol (PVA-PEG), of an active substance and of a hydrophilic gelling agent.

Abstract: The present invention relates to the chemical stabilization of testosterone contained in self-adhesive transdermal devices by way of the association of a desiccant agent with said device within a sealing packaging. The use of a desiccant agent makes it possible to limit the chemical degradation of the testosterone to androstenedione and other impurities and accordingly ensures storage of said device over periods of up to thirty-six months.

Abstract: The invention relates to a self-adhesive transdermal device for the administration of testosterone and/or at least one of the derivatives thereof, comprising successively at least one support layer, a self-adhesive matrix layer and a detachable protective layer, whereby the matrix layer comprises at least one self-adhesive polymer, at least one formulating adjuvant for the matrix layer, at least one solvent chosen from the group made up of solvents of testosterone or the derivatives thereof and testosterone and/or at least one of the derivatives thereof in an oversaturated solution. The device has excellent testosterone permeation qualities and excellent cutaneous tolerance and adhesion qualities. The invention also relates to a method for the production of said device and the use thereof for a medicament, i.e. within the framework of a testosterone replacement therapy.

Abstract: The invention relates to a self-adhesive transdmal device for the administration of testosterone and/or at least one of the derivatives thereof, comprising successively at least one supprt layer, a self-adhesive matrix layer and a detachable protective layer, whereby the matrix layer comprises at least one self-adhesive polymer, at least one formulating adjuvant for the matix layer, at least one solvent chosen from the group made up of solvents of testosterone or the derivatives thereof and testosterone and/or at least one of the derivatives thereof in an oversaturated solution. The device has excellent testosterone permeation qualities and excellent ous tolerance and adhesion qualities. The invention also relates to a method for the production of said device and the use thereof for a mulicament, i.e. within the framework of a testosterone replacement tberapy.

Abstract: The invention concerns a topical pharmaceutical preparation, characterized in that it consists of the combination of an oxan and a pharmaceutically acceptable excipient for transdermal delivery of said oxan.

Abstract: The invention concerns a self-adhesive transdermal device comprising at least two chambers such that the first chamber is a reservoir-type transdermal device (2) and the second chamber is a matrix-type transdermal device (6) located at the periphery of the first chamber. The invention is characterised in that said two devices contain the same active principle.

Abstract: The present invention relates to a sustained-release tablet, characterized in that it comprises as active principle isosorbide 5-mononitrate (5-ISMN) in the form of a powder having a particle size of 80 .mu.m to 500 .mu.m, in homogeneous dispersion in a hydrophilic matrix based on at least one swelling component and at least one diluent component.

Abstract: The present invention relates to tablets of the type which contain a homogeneous dispersion of an active principle based on salbutamol or on one of its derivatives in a hydrophilic matrix, ensuring:in vitro, long-term release of the active principle, which is constant and independent of pH, over a time interval of about 12 hours,in vivo, uptake kinetics of the active principle by the organism of zero order over a time interval of 6 hours, the said matrix containing at least one swelling agent and a diluent in a weight ratio of swelling agent/diluent lying between 0.2 and 0.6, and being preferably equal to about 0.4.The present invention also covers the process for the preparation of these tablets.
