<p>The invention relates to semisolid and liquid pharmaceutical administration forms for transdermal application containing a pharmaceutical active ingredient which is photosensitive in the UV range and at least one UV light-absorbing excipient (UV absorber), this being present dissolved or dispersed in the administration form. Advantageously, the administration form according to the invention relates to transdermal gels whose gel base is composed of water, alcohol, at least one gel-forming polymer and optionally further ingredients. Such gels are also designated as hydroalcoholic gels. An administration form containing a photosensitive pharmaceutical active ingredient is made available, the application system realizing a high stability without the disadvantages known when using the conventional semisolid transdermal application forms. At the same time, the harmful concomitant effects, such as, for example, absorption of lightscreen substances into the body possibly resulting from the intentional light protection for the user, are kept as low as possible.</p> |
