Procedure for Stability Testing of Drugs with Complex APIs

1) Purpose

The purpose of this SOP is to define a procedure for conducting stability studies for drugs with complex active pharmaceutical ingredients (APIs) in compliance with relevant regulatory guidelines. This ensures that such drugs maintain their quality, safety, and efficacy throughout their shelf life.

2) Scope

This SOP applies to all personnel involved in the stability testing of drugs with complex APIs, including formulation development, quality control, and regulatory affairs teams.

3) Responsibilities

Formulation Development Team: Responsible for developing drug formulations containing complex APIs and selecting appropriate 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.
