Procedure for Stability Testing of Liposomal Drug Products

1) Purpose

The purpose of this SOP is to define the procedure for conducting stability testing for liposomal drug products in compliance with relevant regulatory guidelines. This ensures that liposomal formulations maintain their integrity, quality, safety, and efficacy throughout their shelf life.

2) Scope

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

3) Responsibilities

Formulation Development Team: Responsible for developing liposomal formulations and selecting suitable packaging materials.
Stability Study Team: Responsible for conducting stability studies according to approved protocols.
Regulatory Affairs Team: Responsible for ensuring compliance with regulatory requirements and submitting stability data to the authorities.

4) Procedure

4.1 Protocol Development

4.1.1 Develop a stability testing protocol that includes parameters specific to liposomal drug products, such as particle size, encapsulation efficiency, and

release profile.

4.1.2 Define storage conditions (e.g., room temperature, refrigerated) 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 consistent formulation throughout the study.

4.2.2 Store samples under specified conditions, with continuous monitoring of environmental conditions.
