Guidelines for Stability Testing of Drug Products as per Indian Regulatory Requirements (CDSCO)
1) Purpose
The purpose of this Standard Operating Procedure (SOP) is to provide guidelines for conducting stability studies for drug products in accordance with the Central Drugs Standard Control Organization (CDSCO) of India. This SOP ensures that stability data supports the quality, safety, and efficacy of drug products throughout their shelf life.
2) Scope
This SOP applies to all personnel involved in the design, execution, and documentation of stability studies for drug products intended for the Indian market.
3) Responsibilities
Stability Testing Team: Responsible for conducting stability studies and documenting results in compliance with CDSCO 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 CDSCO regulatory expectations.
4) Procedure
4.1 Preparation for Stability Testing
4.1.1 Obtain
and review the latest CDSCO guidelines for stability testing of drug products.4.1.2 Develop a stability protocol specific to drug products, including study design, testing schedule, storage conditions, and testing parameters as per CDSCO guidelines.
4.2 Selection of Batches and Samples
4.2.1 Select representative batches of the drug product, typically three primary batches manufactured using
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 CDSCO guidelines, typically including:
- Long-term stability: 30°C ± 2°C/65% 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.
