Store Photostability Samples in Transparent and Protective Packaging
Understanding the Tip: Purpose of dual packaging in photostability testing: Photostability testing involves exposing pharmaceutical products to light to evaluate their stability under light stress conditions. ICH Q1B recommends storing samples in both light-transmitting (transparent) and light-protective (e.g., foil-wrapped or amber) containers during testing to differentiate between light-induced and non-light-induced changes. This setup ensures that…
