Stability Study Accelerated, Real Time or long term and In-Use Stability Study

Stability Study Accelerated, Real Time or long term and In-Use Stability Study Accelerated Stability ​Goal: Predict shelf life and evaluate the impact of short-term "stress" (e.g., shipping). ​Conditions: 40^\circ\text{C} \pm 2^\circ\text{C} / 75\% \pm 5\% RH. ​Duration: 6 months. Long-Term (Real-Time) ​Goal: Establish the actual, legal expiration date. ​Conditions: 25^\circ\text{C} \pm 2^\circ\text{C} / 60\% \pm 5\% RH (Zone II) or 30^\circ\text{C} \pm 2^\circ\text{C} / 65\% RH (Zone IVa). ​Duration: Minimum 12 months for filing; continues for the duration of the intended shelf life. In-Use Stability ​Goal: Ensure safety and efficacy after the seal is broken. ​Scope: Focuses on multi-dose products (e.g., eye drops, reconstituted powders, or large-volume parenterals). ​Focus: Monitors physical changes, "clumping," chemical degradation, and microbial growth introduced by repeated opening.
