Submit at Least 6 Months of Long-Term Data for New Drug Applications

Understanding the Tip: Why 6 months of data is the baseline: New drug applications (NDAs) require scientific evidence to justify proposed shelf life and storage conditions. At least 6 months of real-time, long-term stability data is the regulatory minimum needed to establish preliminary product behavior over time. This data provides an early trend of degradation,…
