Standard Operating Procedure for In-process Testing for Aerosols

1) Purpose

The purpose of this SOP is to define procedures for conducting in-process testing during aerosol production in the pharmaceutical industry. In-process testing ensures that critical quality attributes are monitored and controlled throughout the manufacturing process.

2) Scope

This SOP applies to all stages of aerosol production at [Company Name], including formulation, filling, and packaging processes where in-process testing is necessary to verify product quality and compliance.

3) Responsibilities

Quality Control (QC) Analysts: Perform in-process testing according to defined procedures.
Production Operators: Collect samples and assist in in-process testing activities.
Quality Assurance (QA) Manager: Oversees compliance with in-process testing procedures and documentation.

4) Procedure

4.1 Sampling:
4.1.1 Collect representative samples at specified intervals during production according to sampling plan.
4.1.2 Ensure samples are collected using validated sampling techniques to maintain sample integrity.

4.2 Testing Procedures:
4.2.1 Perform in-process tests as per approved test methods and specifications.
4.2.2 Include tests for critical parameters such as pH, viscosity, fill weight, and propellant content.

4.3 Recordkeeping:
4.3.1 Record test results accurately and promptly in designated logbooks or electronic records.
4.3.2 Document any deviations or out-of-specification results and initiate investigation and corrective actions as needed.

4.4 Compliance Verification:
4.4.1 Verify compliance
