Guidelines for Stability Testing of New Dosage Forms as per ICH Q1C
1) Purpose
The purpose of this Standard Operating Procedure (SOP) is to outline the procedure for conducting stability testing of new dosage forms in accordance with the ICH Q1C guidelines. This SOP ensures that the stability data generated supports the quality, safety, and efficacy of new dosage forms throughout their shelf life.
2) Scope
This SOP applies to all personnel involved in the design, execution, and documentation of stability studies for new dosage forms of drug products intended for global
3) Responsibilities
Stability Testing Team: Responsible for conducting stability studies, collecting data, and documenting results in compliance with ICH Q1C 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
4) Procedure
4.1 Preparation for Stability Testing
4.1.1 Obtain and review the latest version of the ICH Q1C guidelines for stability testing of new dosage forms.
4.1.2 Identify the new dosage form 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 design, testing schedule, storage conditions, and testing parameters as per ICH Q1C guidelines.
4.2 Selection of Batches and Samples
4.2.1 Select representative batches of the new dosage form, 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 as per ICH Q1C guidelines, typically including:
- Long-term stability: 25°C ± 2°C/60% RH ± 5% RH
- Accelerated stability: 40°C ± 2°C/75% RH ± 5% RH
- Intermediate stability (if needed): 30°C ± 2°C/65% 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 or intermediate 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.
