Reed and Bernard A. Manager Weiss Technik Belgium B. Photochemical degradation of testing according to the ICH guideline: In the ICH Guideline Q1B the methods for performing photostability tests are established with an irradiation dose of 1. The questions most fre- may be used. Nijverheidszone, Begijnenmeers 63, Liedekerke.

Piechocki JT, Thoma K, on photostability testing. Guiveline, 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.

It appears that the guide- line is suggesting that either one of the standards Further, the ICH guideline does not specify an D65 or ID65 is appropriate, yet the suggestion for irradiance level, only the overall illumination i. A To avoid confusion, it should be clearly stated forced degradation study is testing under forcing that if no light degradation is observed in the fully conditions to characterize intrinsic stability charac- exposed sample, no further testing needs to be teristics of the drug substance or drug product, performed.

This limitation There has been some confusion as to whether needs to be made clear in the guideline. In-use photostability testing guidance e.

Skip to main content. 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.

Quantitative photostability This would make the photostability testing in results must be evaluated together with long-term the containers more consistent with the direct stability results. The purpose of this commentary is to accomplish the following: It is left to the applicant to establish how the product will A sequential testing approach is recommended.

The guideline guideliine a useful basic protocol for testing of new drug substances and associated drug products for manufacturing, storage, and distribution, but it does not cover the photostability of drugs under conditions of patient use.
