Abstract (en)

[origin: DE19912623A1] 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.
