Guidelines for Stability Testing of Pediatric Formulations

1) Purpose

The purpose of this SOP is to establish procedures for conducting stability studies for pediatric formulations. Stability studies are essential to ensure that pediatric formulations maintain their safety, efficacy, and quality throughout their intended shelf life under various storage conditions.

2) Scope

This SOP applies to all pediatric drug formulations manufactured, tested, and stored by the organization. It covers both oral and parenteral dosage forms, including suspensions, solutions, and chewable tablets.

3) Responsibilities

Research and Development (R&D) Team: Responsible for designing the stability study protocol.

Quality Control (QC) Team: Responsible for conducting the required tests and documenting results.

Regulatory Affairs Team: Responsible for ensuring compliance with pediatric regulatory requirements.

4) Procedure

4.1 Study Design:

1. Define the stability parameters to be tested, such as potency, pH, microbial limits, and viscosity.
2. Determine storage conditions, including temperature and humidity, based on the formulation type and regulatory guidelines.
3. Prepare a stability

   protocol outlining the study’s objectives, sampling schedule, and analytical methods.

4.2 Sample Preparation:

1. Prepare samples from representative production batches and store them in their intended packaging.
2. Label samples with appropriate information, including batch number, storage conditions, and test intervals.
3. Place samples in designated stability chambers for storage.

4.3 Testing Schedule:

1. Conduct initial testing on all samples to establish baseline data.
2. Perform stability tests at predetermined intervals to evaluate product integrity over time.
3. Record all test results in the stability study log and analyze data for trends.

4.4 Data Analysis and Reporting:

1. Analyze data to determine if the formulation meets the predefined acceptance criteria.
2. Prepare a stability study report summarizing findings, conclusions, and recommended shelf life.
3. Submit the report for review by the QA department.
