Procedure for Stability Testing of Drug Products in Multi-Layered Packaging

1) Purpose

The purpose of this SOP is to define a procedure for conducting stability studies for drug products in multi-layered packaging in compliance with relevant regulatory guidelines. This ensures that these products maintain their intended quality, safety, and efficacy throughout their shelf life.

2) Scope

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

3) Responsibilities

Packaging Development Team: Responsible for designing and selecting appropriate multi-layered packaging materials.
Stability Study Team: Responsible for conducting stability studies according to approved protocols.
Quality Assurance Team: Responsible for ensuring data compliance with regulatory requirements.

4) Procedure

4.1 Protocol Development
