The invention relates to a method for improving the stability of stored and/or used light-sensitive therapeutic systems or components thereof, such as active ingredients or auxiliary agents, using light stabilising substances which absorb or reflect electromagnetic waves. The inventive method uses absorption or reflection elements whose absorptive or reflective spectrum encompasses the wavelength range which is responsible for the instability of the light- sensitive substance or components thereof.
Procédé d'augmentation de la stabilité de systèmes thérapeutiques photosensibles ou de leurs constituants, tels que des principes actifs ou substances auxiliaires, lors du stockage et/ou de l'utilisation desdits systèmes, grâce à l'utilisation de substances de protection contre la lumière qui absorbent ou réfléchissent les ondes électromagnétiques. Selon ledit procédé, on utilise des substances d'absorption ou de réflexion dont le spectre d'absorption ou de réflexion englobe le domaine des longueurs d'ondes qui est responsable de l'instabilité de la substance photosensible ou de ses constituants.
