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.

Option 2 radiation sources lamps. Option 1 light sources. Clarity on interpretation of results is needed. Enter the email address you signed up with and we’ll email you a reset link. Clarity on length of exposure when using Option 1 conditions is needed. 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.
