Freeze-Thaw Studies for Lyophilized Products Designing Freeze-Thaw Studies for Lyophilized Pharmaceutical Products Lyophilized (freeze-dried) pharmaceutical products are widely used for their enhanced stability and extended shelf-life. However, despite being dried, lyophilized formulations are not immune to the risks posed by freeze-thaw cycling. Excursions during transportation or storage can subject lyophilized vials or their reconstituted forms…
Validation of Photostability Testing Equipment How to Validate Photostability Testing Equipment for Regulatory Compliance Photostability testing is a regulatory requirement under ICH Q1B for evaluating the light sensitivity of pharmaceutical products. However, the reliability of photostability data hinges on the proper validation and performance qualification of the testing equipment used—typically light chambers equipped with UV…
