(57) Abstract :<br />

The present invention relates to the chemical stabilization <strong>of</strong> testosterone contained in self-adhesive transdermal devices by way <strong>of</strong> the<br />

association <strong>of</strong> a desiccant agent with said device within a sealing packaging. The use <strong>of</strong> a desiccant agent makes it possible to limit the<br />

chemical degradation <strong>of</strong> the testosterone to <strong>and</strong>rostenedione <strong>and</strong> other impurities <strong>and</strong> accordingly ensures storage <strong>of</strong> said device over<br />

periods <strong>of</strong> up to thirty-six months.<br />
