Using Prior Knowledge in QbD-Driven Stability Planning

In pharmaceutical development, the Quality by Design (QbD) approach emphasizes scientific understanding and proactive quality planning. One of its most powerful but often underutilized tools is the use of prior knowledge—data and insights gathered from previous development projects, products, or platforms. When integrated into stability planning, this information can drastically reduce unnecessary testing, streamline timelines,…

Apply Risk-Based Strategies to Minimize Stability Testing Commitments

Understanding the Tip: What risk-based stability planning means: Risk-based approaches evaluate the criticality of stability testing based on formulation characteristics, manufacturing history, and existing data. This strategy allows companies to reduce repetitive or redundant testing without compromising product safety or compliance. It involves tailoring testing frequency, sample size, or study duration based on scientifically justified…
