Procedure for Stability Testing of Fixed-Dose Combination Products
1) Purpose
The purpose of this SOP is to define the procedures for conducting stability studies on fixed-dose combination (FDC) products to comply with regulatory guidelines. This SOP ensures that stability data for FDC products is generated in accordance with applicable regulatory requirements, ensuring the quality, safety, and efficacy of the product throughout its shelf life.
2) Scope
This SOP applies to all personnel involved in the planning, execution, monitoring, and reporting of stability studies for fixed-dose combination products. It includes both new FDC products and changes to existing products under various regulatory jurisdictions.
3) Responsibilities
Formulation Development Team: Responsible for developing and finalizing the FDC product formula and selecting suitable packaging.
Stability Study Team: Responsible for conducting stability studies as per the approved protocol.
Regulatory Affairs Team: Responsible for ensuring that stability testing complies with the
