API Degradation Pathways and Their Effect on Expiry Dating

Drug products are only as stable as their active pharmaceutical ingredients (APIs). Understanding the degradation behavior of APIs is crucial for setting scientifically justified expiry dates. In this tutorial, we explore common degradation pathways, how they impact expiry dating, and what pharma professionals should consider when planning stability studies and regulatory filings. 🔬 Why Degradation…

Factors Affecting Drug Shelf Life (Storage Conditions, Container, Light, etc.), Shelf Life and Expiry

Linking Protocol Design to Label Claim Shelf Life

Designing a stability study protocol isn’t just a procedural task—it directly influences the shelf life printed on the product’s label. Regulatory agencies such as the USFDA, EMA, and CDSCO expect a clear link between protocol structure and the justification for the expiry date. Without a robust design, your product may be assigned a shorter-than-necessary shelf…

Timeline Management in Multi-Center ICH Stability Studies

Timely execution of ICH stability studies is essential for regulatory submissions and product approvals. When studies span multiple global centers—across various climatic zones, regulatory jurisdictions, and laboratory systems—timeline management becomes exponentially complex. This guide explores best practices, tools, and compliance strategies for successfully managing timelines in multi-center ICH stability studies. 📌 Understanding ICH Stability Timelines…

Store Stability Samples from Validated Commercial Batches for Accurate Shelf-Life Data

Understanding the Tip: Why commercial validation matters in stability studies: Stability data is used to determine how long a product remains safe and effective under specified storage conditions. If the tested batch isn’t produced using a validated commercial process, the results may not reflect the true behavior of the product in the real world. Validated…

Include Three Primary Batches in Stability Studies for Robust Shelf-Life Support

Understanding the Tip: Why three batches are the standard: Stability studies based on a single batch provide limited insight into variability. Including three primary batches—manufactured at pilot or production scale—ensures that your data reflects consistent performance and accounts for batch-to-batch differences. This approach supports statistical evaluation and strengthens confidence in the proposed shelf life and…
