Guidelines for Stability Testing of Drug Products as per ASEAN Guidelines
1) Purpose
The purpose of this Standard Operating Procedure (SOP) is to outline the procedure for conducting stability testing of drug products in accordance with the ASEAN (Association of Southeast Asian Nations) guidelines. This SOP ensures that stability data generated is adequate to support the quality, safety, and efficacy of products throughout their shelf life under ASEAN regulatory standards.
2) Scope
This SOP applies to all personnel involved in the design, execution, and documentation of stability studies for drug products intended for the ASEAN market.
3) Responsibilities
Stability Testing Team: Responsible for conducting stability studies, collecting data, and documenting results in compliance with ASEAN guidelines.
Quality Assurance (QA) Team: Responsible for reviewing and approving stability protocols and reports, ensuring compliance with regulatory requirements.
Regulatory Affairs Team: Responsible for ensuring the study design and results meet
4) Procedure
4.1 Preparation for Stability Testing
4.1.1 Obtain and review the latest version of the ASEAN guidelines for stability testing.
4.1.2 Identify the drug product to be tested and determine the type of stability study required (e.g., long-term, accelerated, or intermediate).
4.1.3 Develop a stability protocol that includes study
4.2 Selection of Batches and Samples
4.2.1 Select representative batches of the drug product, typically three primary batches manufactured using the proposed production process.
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 ASEAN guidelines, typically including:
- Long-term stability: 30°C ± 2°C/75% 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 the 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.
