Standard Operating Procedure for Cleaning Validation in Transdermal Patches Production

1) Purpose

The purpose of this SOP is to establish procedures for the validation of cleaning processes in transdermal patches production to ensure removal of residues from equipment surfaces, thereby preventing cross-contamination and maintaining product quality.

2) Scope

This SOP applies to the cleaning validation of equipment used in the manufacturing and packaging of transdermal patches within the facility.

3) Responsibilities

The Quality Assurance (QA) Department is responsible for overseeing the cleaning validation process. Production personnel are responsible for executing cleaning procedures and providing necessary documentation.

4) Procedure

4.1 Cleaning Validation Plan

• 4.1.1 Develop a cleaning validation protocol outlining the objectives, acceptance criteria, sampling methods, and analytical techniques to be used.
• 4.1.2 Obtain approval of the cleaning validation protocol from QA and other relevant departments before initiating cleaning validation studies.

4.2 Pre-Cleaning Procedures

• 4.2.1 Disassemble equipment components and visually inspect for cleanliness before initiating cleaning procedures.
• 4.2.2 Flush equipment with appropriate solvents or cleaning agents as per approved cleaning procedures to remove visible residues.

4.3 Cleaning Validation Study

• 4.3.1 Execute cleaning validation studies according to the approved protocol, including worst-case scenarios and representative product residues.
• 4.3.2 Collect swab or rinse samples from critical equipment surfaces post-cleaning for analysis of
