Guidelines for Stability Testing of Veterinary Drugs per US FDA and EMA Guidelines
1) Purpose
The purpose of this Standard Operating Procedure (SOP) is to outline the procedure for conducting stability testing of veterinary drugs in accordance with US FDA and EMA guidelines. This SOP ensures that stability data supports the quality, safety, and efficacy of veterinary drugs throughout their shelf life.
2) Scope
This SOP applies to all personnel involved in the design, execution, and documentation of stability studies for veterinary drugs intended for the US and European markets.
3) Responsibilities
Stability Testing Team: Responsible for conducting stability studies and documenting results in compliance with US FDA and EMA guidelines.
Quality Assurance (QA) Team: Responsible for reviewing and approving stability study protocols and reports.
Regulatory Affairs Team: Responsible for ensuring that stability studies meet the regulatory expectations of the US FDA
and EMA.4) Procedure
4.1 Preparation for Stability Testing
4.1.1 Obtain and review the latest US FDA and EMA guidelines for stability testing of veterinary drugs.
4.1.2 Develop a stability protocol specific to veterinary drugs, including study design, testing schedule, storage conditions, and testing parameters as per both guidelines.
4.2 Selection of Batches and Samples
4.2.1 Select representative
4.2.2 Prepare sufficient samples to cover the entire study duration, considering the number of time points and tests to be conducted.
4.3 Defining Storage Conditions and Time Points
4.3.1 Define the storage conditions according to both US FDA and EMA guidelines, typically including:
- Long-term stability: 25°C ± 2°C/60% RH ± 5% RH
- Accelerated stability: 40°C ± 2°C/75% RH ± 5% RH
4.3.2 Establish the time points for sampling, such as 0, 3, 6, 9, 12, 18, and 24 months for long-term studies, and additional time points for accelerated studies.
4.4 Conducting Stability Tests
4.4.1 Store samples under the defined conditions, monitoring temperature and humidity to ensure compliance with the set parameters.
4.4.2 At each specified time point, remove samples and conduct stability-indicating tests, including physical, chemical, microbiological, and functional tests, as applicable.
4.4.3 Record all results meticulously in stability data sheets, ensuring accuracy and traceability of data.
