Standard Operating Procedure for Conducting Process Validation for Transdermal Patches

1) Purpose

The purpose of this SOP is to define the procedures for conducting process validation studies for transdermal patches to ensure consistent product quality, reliability, and compliance with regulatory requirements.

2) Scope

This SOP applies to all stages of process validation, including process design, qualification, and ongoing monitoring, for transdermal patch manufacturing processes within the facility.

3) Responsibilities

The Quality Assurance (QA) Department is responsible for overseeing and coordinating process validation activities outlined in this SOP. Production, Engineering, and Quality Control (QC) departments collaborate in executing validation protocols and documenting results.

4) Procedure

4.1 Process Design and Development

• 4.1.1 Define critical process parameters (CPPs) and their acceptable ranges based on product formulation and regulatory requirements.
• 4.1.2 Conduct risk assessments (e.g., FMEA) to identify potential failure modes and develop mitigation strategies.

4.2 Installation Qualification (IQ)

• 4.2.1 Verify and document that equipment and utilities are installed correctly according to design specifications and manufacturer recommendations.
• 4.2.2 Review equipment manuals, calibration records, and maintenance logs to ensure compliance with IQ requirements.

4.3 Operational Qualification (OQ)

• 4.3.1 Validate and document equipment performance under operational conditions to demonstrate consistency and reliability.
• 4.3.2 Test equipment functions, alarms, and controls to verify that they operate within
