Procedure for Stability Studies of Nanomedicines

1) Purpose

The purpose of this SOP is to establish the procedure for conducting stability testing for nanomedicines to comply with regulatory guidelines. This ensures that nanomedicines retain their nanoscale properties, quality, safety, and efficacy throughout their intended shelf life.

2) Scope

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

3) Responsibilities

Formulation Development Team: Responsible for creating nanomedicine formulations and determining suitable packaging materials.
Stability Study Team: Responsible for carrying out stability studies in accordance with approved protocols.
Regulatory Affairs Team: Responsible for ensuring that all stability data meets regulatory requirements and preparing it for submission to regulatory authorities.

4) Procedure

4.1 Development of Stability Protocol

4.1.1 Design a stability testing protocol specific to nanomedicines, considering parameters like particle size, zeta potential, encapsulation efficiency, and release characteristics.

4.1.2

Determine storage conditions (e.g., room temperature, refrigerated) and testing intervals (e.g., 0, 3, 6, 12 months) in line with regulatory guidelines.

4.2 Sample Preparation and Storage

4.2.1 Prepare samples in their final packaging for stability testing, ensuring uniformity in formulation throughout the testing period.

4.2.2 Store samples under defined conditions, and use validated equipment to
