Procedure for Stability Testing of Drug Products in Extreme Conditions

1) Purpose

The purpose of this SOP is to establish a procedure for conducting stability studies for drug products under extreme conditions in compliance with regulatory guidelines. This ensures that drug products maintain their quality, safety, and efficacy in various challenging environments.

2) Scope

This SOP applies to all personnel involved in the stability testing of drug products exposed to extreme conditions, including formulation development, quality control, and regulatory affairs teams.

3) Responsibilities

Formulation Development Team: Responsible for developing formulations designed to withstand extreme conditions.
Stability Study Team: Responsible for conducting stability studies under extreme conditions according to approved protocols.
Regulatory Affairs Team: Responsible for ensuring compliance with regulatory requirements and submitting stability data to authorities.

4) Procedure

4.1 Protocol Development

4.1.1 Develop a stability testing protocol that includes conditions such as extreme temperatures

(hot and cold), humidity, and light exposure.

4.1.2 Define storage conditions and testing intervals (e.g., 0, 3, 6, 12 months) according to regulatory guidelines.

4.2 Sample Preparation and Storage

4.2.1 Prepare samples in their final packaging for stability testing, ensuring packaging is suitable for extreme conditions.

4.2.2 Store samples under specified extreme conditions, with continuous monitoring
