Standard Operating Procedure for Compliance with US FDA Stability Testing Requirements

1) Purpose

The purpose of this SOP is to establish a standardized procedure for conducting stability testing of drug products to ensure compliance with US FDA stability testing requirements, thereby confirming the quality, safety, and efficacy of the products throughout their shelf life.

2) Scope

This SOP applies to all drug substances and products manufactured, tested, or stored within the facility for which stability data is required to meet US FDA requirements. It is relevant to departments involved in production, quality control, quality assurance, and regulatory compliance.

3) Responsibilities

• Quality Control (QC) Team: Performs stability testing according to FDA guidelines.
• Quality Assurance (QA) Team: Reviews and approves protocols and ensures compliance with FDA requirements.
• Regulatory Affairs Team: Ensures all stability data meets FDA submission standards.

4) Procedure

1. Preparation of Stability Protocol
   1. Develop a protocol outlining storage conditions, test

      intervals, and analytical methods in line with FDA guidelines.
   2. Submit the protocol for review and approval by the QA team.
2. Execution of Stability Studies
   1. Store samples under specified conditions (e.g., 25°C/60% RH, 30°C/75% RH) in designated stability chambers.
   2. Conduct analytical tests at each defined time point to assess stability parameters.
   3. Record and document all test results,
