Operational Qualification Protocol for the Patch Coating Machine

Objective

The objective of this Operational Qualification (OQ) protocol is to verify that the Patch Coating Machine operates within specified parameters to ensure consistent coating of the drug adhesive layer onto the backing film for transdermal patches.

Scope

This protocol applies to the Patch Coating Machine (Knife-over-roll / Slot Die) used in the production area for transdermal patches. It encompasses the verification of critical parameters and compliance with the applicable regulations and guidelines.

Responsibilities

The following personnel are responsible for the execution and approval of this protocol:

• Validation Team: Execute the protocol and document results.
• Quality Assurance: Review and approve the protocol and results.
• Production Team: Operate the equipment during testing.

Prerequisites

Ensure the following prerequisites are met before executing this protocol:

• All personnel are trained on equipment operation and validation procedures.
• The Patch Coating Machine is installed and operational.
• All required materials and resources are available.

Equipment Description

The Patch Coating Machine (Knife-over-roll / Slot Die) is designed to coat a drug adhesive layer onto a backing film. The machine operates under controlled conditions to ensure the quality and consistency of the transdermal patches produced.

Test Plan

Detailed Test Cases

Each test case will be executed according to the following detailed procedures:

Test Case OQ-001: Verify Coating Thickness

1. Set up the Patch Coating Machine according to operational guidelines.

2. Run a batch and measure the coating thickness at specified intervals.

3. Document all measurements and compare against acceptance criteria.

Test Case OQ-002: Verify Coating Speed

1. Start the machine and set the desired speed.

2. Use the PLC to monitor and log the actual speed during operation.

3. Compare logged data against acceptance criteria.

Test Case OQ-003: Verify Coating Temperature

1. Set the machine to the required temperature.

2. Monitor temperature using calibrated sensors during operation.

3. Document temperature readings and ensure they meet acceptance criteria.

Test Case OQ-004: Verify Coating Tension

1. Adjust the machine to the specified tension settings.

2. Use tension measurement tools to verify actual tension during operation.

3. Document findings and ensure compliance with acceptance criteria.

Deviations

Any deviations from the acceptance criteria must be documented and evaluated for impact on product quality. A corrective action plan should be developed as necessary.
