Design Qualification Protocol for Jet Mill / Spiral Mill in Inhaled NDDS Powder Production

Meta Description: This document outlines the Design Qualification protocol for Jet Mill and Spiral Mill used in the micronization of API for inhalation, focusing on critical parameters and compliance with URS Annex 11 and Annex 15.

Tags: Equipment Validation, Design Qualification, NDDS, Jet Mill, Spiral Mill, R&D, Production

Objective

The objective of this Design Qualification (DQ) protocol is to ensure that the Jet Mill / Spiral Mill is suitable for its intended purpose in the micronization of Active Pharmaceutical Ingredients (APIs) for inhalation, meeting all critical parameters and regulatory requirements.

Scope

This protocol applies to the validation of the Jet Mill / Spiral Mill used in the R&D and Production areas for the manufacture of inhaled NDDS powders, specifically engineered particles.

Responsibilities

• Validation Team: Responsible for executing the DQ protocol and documenting results.
• Quality Assurance: Ensures compliance with regulatory requirements and internal standards.
• Engineering: Provides technical support and equipment specifications.

Prerequisites

• Completion of User Requirement Specification (URS).
• Installation Qualification (IQ) must be completed prior to DQ execution.
• Staff training on equipment operation and safety protocols.

Equipment Description

The Jet Mill / Spiral Mill is designed to micronize APIs into fine powders suitable for inhalation. The equipment operates under controlled pressure and feed rates to achieve desired particle size distribution (PSD) while maintaining containment standards.

Test Plan

Detailed Test Cases

Test Case DQ-001-01: Verify Pressure Feed Rate

Procedure: Measure and document the pressure feed rate during operation.

Acceptance Criteria: Feed rate must be within specified limits as per URS.

Evidence: Calibration records will be maintained for review.

Test Case DQ-001-02: Assess PSD Control

Procedure: Conduct particle size analysis on micronized samples.

Acceptance Criteria: Results must meet the defined PSD specifications.

Evidence: A particle size analysis report will be generated and archived.

Test Case DQ-001-03: Evaluate Containment

Procedure: Perform a containment test to ensure no leakage during operation.

Acceptance Criteria: Zero leakage must be observed during the testing.

Evidence: A containment testing report will be generated and archived.

Deviations

Any deviations from the established acceptance criteria must be documented and assessed for impact on product quality and compliance. A formal deviation report should be submitted for review and approval.
