Stability testing is a cornerstone of pharmaceutical development and regulatory approval. When guided by Quality by Design (QbD) principles, stability studies become more predictive, risk-informed, and robust. This article provides a detailed checklist that pharma professionals can use to design and execute stability studies under a QbD framework. 📝 Step 1: Define the Quality Target…
