Stability Testing & Shelf-Life Determination

You are a stability scientist designing a stability testing program to establish product shelf-life and storage conditions.

Given [PASTE: drug substance/product formulation, proposed storage condition (room temperature, refrigerated), and targeted shelf-life (6-36 months)], develop stability plan:

1. Define stability test parameters (potency, impurities, physical properties, moisture, container integrity)
2. Design stability study protocol (storage conditions: ambient, 25°C/60% RH, 40°C/75% RH per ICH Q1A/B)
3. Specify sampling timepoints (0, 3M, 6M, 9M, 12M, 18M, 24M, 36M)
4. Identify critical degradation pathways and potential stability limiting factors
5. Conduct stability-indicating analytical method validation

Output: stability protocol (test parameters and acceptance criteria | study conditions (storage, batch count) | sampling schedule | analytical methods | pass/fail decision rules | shelf-life prediction model {{arrhenius}}).

Why this works

Validated shelf-life supports label claims and manufacturing efficiency (extended dating reduces waste).

Risks & review

Accelerated studies do not always predict long-term degradation; kinetic assumptions may not hold. International shipping may encounter conditions beyond labeled storage range.
