Patch Coating Machine (Knife-over-roll / Slot Die) – PQ Protocol

Performance Qualification Protocol for Patch Coating Machine in Transdermal Patch Production

Document Number: PQ-001

Version: 1.0

Effective Date: [Insert Date]

Prepared By: [Insert Name]

Reviewed By: [Insert Name]

Approved By: [Insert Name]

Objective

The objective of this Performance Qualification (PQ) protocol is to verify that the Patch Coating Machine operates consistently and reliably within specified parameters to ensure the quality of transdermal patches produced.

Scope

This protocol applies to the validation of the Patch Coating Machine used in the production area for the coating of drug adhesive layers onto backing films for transdermal patches.

Responsibilities

  • Validation Team: Responsible for executing the PQ protocol and documenting results.
  • Quality Assurance: Responsible for reviewing and approving the PQ documentation.
  • Production Team: Responsible for the operation of the Patch Coating Machine during qualification activities.

Prerequisites

  • Complete Installation Qualification (IQ) and Operational Qualification (OQ) for the Patch Coating Machine.
  • Availability of all necessary materials and equipment for testing.
  • Training of personnel on the operation of the Patch Coating Machine.

Equipment Description

The Patch Coating Machine (Knife-over-roll / Slot Die) is designed to apply a uniform layer of drug adhesive onto backing films. Key features include adjustable coating thickness, speed control, temperature regulation, and tension monitoring. PLC logs are utilized for data recording and analysis.

Test Plan

Test ID Procedure Acceptance Criteria Evidence
PQ-001 Measure coating thickness at specified intervals. Coating thickness within specified range (URS Annex 11). Thickness measurement logs.
PQ-002 Record coating speed during operation. Speed within specified limits. Speed logs from PLC.
PQ-003 Monitor temperature during coating. Temperature remains within acceptable range. Temperature logs from PLC.
PQ-004 Check tension during operation. Tension within specified limits. Tension logs from PLC.

Detailed Test Cases

Test Case 1: Coating Thickness Measurement

Procedure: Measure the coating thickness at three different points across the film width. Repeat for three consecutive batches.

Acceptance Criteria: Coating thickness must be within the specified range outlined in the URS.

Evidence: Documented thickness measurements and comparison against acceptance criteria.

Test Case 2: Coating Speed Monitoring

Procedure: Record the coating speed during the operation of the machine for three consecutive batches.

Acceptance Criteria: Speed must remain within specified limits.

Evidence: PLC speed logs.

Test Case 3: Temperature Monitoring

Procedure: Monitor and record the temperature of the coating area during operation for three consecutive batches.

Acceptance Criteria: Temperature must remain within the acceptable range.

Evidence: Documented temperature logs from PLC.

Test Case 4: Tension Monitoring

Procedure: Check the tension applied to the film during the coating process for three consecutive batches.

Acceptance Criteria: Tension must be within specified limits.

Evidence: Tension logs from PLC.

Deviations

Any deviations from the acceptance criteria must be documented, including a description of the deviation, potential impact on product quality, and corrective actions taken.
