1. Purpose

The purpose of this SOP is to define the procedure for conducting accelerated stability testing on capsules to evaluate their stability under accelerated conditions. This testing helps predict the long-term shelf-life and potential degradation of capsules under accelerated environmental conditions.

2. Scope

This SOP applies to all accelerated stability tests conducted on capsules. It covers the setup, monitoring, and testing of capsules under accelerated storage conditions to assess their stability and degradation over time.

3. Responsibilities

4. Accountability

The Quality Control Manager is accountable for ensuring that the accelerated stability study is properly executed and that the data generated is accurate. The Regulatory Affairs Manager ensures compliance with regulatory guidelines. The Production Manager ensures that the required batches of capsules are provided and compliant with standards.

5. Procedure

5.1 Pre-Study Preparation

Before initiating the accelerated stability study, ensure the following:

  1. Define Study Parameters
    1. Identify the capsules to be tested based on batch number, formulation, and anticipated shelf-life.
    2. Define the accelerated storage conditions, such as temperature (e.g., 40°C ± 2°C) and humidity (e.g., 75% RH), to accelerate degradation and mimic long-term storage conditions in a shorter timeframe.
    3. Set the time intervals for testing (e.g., 0, 3, 6, 9, 12 months).
  2. Prepare Stability Study Protocol
    1. Prepare and approve a stability study protocol, outlining the study design, test parameters, and sampling plan.
    2. Ensure the study protocol is aligned with ICH Q1A (R2) and other relevant regulatory guidelines for accelerated stability testing.
  3. Label and Identify Samples
    1. Label all stability samples clearly with product details, batch number, storage conditions, and the start date of the study.
  4. Prepare Environmental Conditions
    1. Ensure stability chambers are calibrated and set to the desired accelerated conditions for temperature and humidity.
    2. Monitor environmental conditions within the stability chambers to maintain the required parameters throughout the study period.

5.2 Conducting the Accelerated Stability Study

Follow these steps during the study:

  1. Store Samples Under Accelerated Conditions
    1. Place the samples in the stability chamber, maintaining the specified temperature and humidity conditions.
    2. Ensure that the samples are protected from external light and other environmental factors that may affect their stability.
  2. Monitor Environmental Conditions
    1. Continuously monitor and record the temperature and humidity inside the stability chamber to ensure that the conditions remain within the defined range.
    2. Adjust the environmental controls if necessary to maintain the required parameters.
  3. Periodic Sampling
    1. At each designated time point (e.g., 0, 3, 6, 9, 12 months), remove a sample of capsules from the stability chamber for testing.
    2. Ensure that the sampling is done in a controlled environment to prevent contamination or alteration of the samples.
  4. Conduct Testing on Samples
    1. Test the samples for relevant parameters such as potency, dissolution, disintegration, appearance, moisture content, and microbial contamination.
    2. Document the test results and any deviations from the expected outcomes.

5.3 Data Analysis and Reporting

After completing the study, ensure the following:

  1. Evaluate Stability Data
    1. Analyze the stability data to assess the capsules’ degradation over time, focusing on changes in potency, dissolution, and other quality parameters.
    2. Compare the data with the acceptance criteria established in the stability study protocol to determine whether the capsules remain within specifications.
  2. Prepare Stability Report
    1. Prepare a detailed stability report summarizing the findings, including data analysis, conclusions, and shelf-life predictions.
    2. Include any recommendations based on the stability study outcomes, such as changes in storage conditions, packaging materials, or product formulations.
  3. Review and Approval
    1. Review the stability report for completeness and compliance with GMP and regulatory requirements.
    2. Ensure that the report is approved by the Quality Control Manager before submitting it for regulatory filing or product release decisions.

5.4 Post-Study Actions

After completing the accelerated stability study, ensure the following:

  1. Archive Study Data
    1. Archive all study data, including raw data, test results, and reports, according to the company’s data retention policy.
    2. Ensure that all records are stored in a secure and easily accessible manner for future reference and regulatory audits.
  2. Review Results for Product Release
    1. Review the accelerated stability data to assess the product’s viability for long-term storage and its projected shelf-life.
    2. Based on the results, determine whether the batch meets the required quality standards and is suitable for release.
