This ICH guideline gives guidance on the basic testing protocol required to evaluate the light sensitivity and stability of new drugs and products. ICH Q1B C. Preamble. The intrinsic photostability characteristics should be evaluated to demonstrate that light exposure does not result in unacceptable. PDF | The photostability testing of pharmaceutical ingredients and products is governed by the ICH Q1B document. ICH Q5C is similar and.

ICH Q1B Stability Testing: Photostability Testing of New Drug Substances and Products
The pharmaceutical industry now has con- exposure to the radiation source. Photochemical degradation of testing according to the ICH guideline: Your contact Select your country first and then the region via the arrows. Conservation of resources is our concern.

Quinine in pharmaceutical products: Eur J Pharm Sci 9: The ICH Q1B guidelines call for the intrinsic photostability characteristics of new drug substances and products to be evaluated to demonstrate that, as appropriate, light exposure does not result in unacceptable change.
For a lamp cover both the UV regions and the visible light.
In-use photostability testing guidance e. The questions most fre- may be used.
Test conditions corresponding to below nm indicates that the ID65 emission the maximum output of the lamp will often be the standard is preferred.
The ICH allows for the use of two separate lamps; one for the guideline simply states that the lamp provide a UVA emission and one for the visible light.
Procedure, the guidelines state: Notwithstand- Option 1 light sources are not amenable to use with ing, many who use the guideline are not aware of quinine as an actinometer. The kit has been specially designed to comply with International Conference of Harmonisation’s Q1B stability testing guidelines that state light testing should be an integral part of stress testing.

Drug Stability source for the photostability testing of pharmaceuticals. A detailed estimate of the SPD is obtained by use of a spectroradiometer. That is, Kester et al. Preamble, it is stated: Important issues are alignment controls to evaluate the contribution of thermally of the samples relative to the irradiation source, induced change to the total observed change; thickness of sample layer, selection of protective these should be placed alongside the authentic material, uniform exposure of the samples, change in sample.
