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.

Photoreactivity of practical interpretation of the ICH guideline and its application biologically active compounds. A detailed estimate of the SPD is obtained by use of a spectroradiometer. Further, these devices cannot be used to obtain an absolute measurement of irradiance or to compare irradiance between sources unless they are calibrated specifically for each source.

Starna’s drug photostability testing kit features a PTFE capped screw cap cell to avoid sample contamination difficulties. Do you have questions, requests or suggestions on our products and solutions?
