Procedure for Validation of Analytical Methods for Aerosol Dosage Forms

1. Purpose

The purpose of this Standard Operating Procedure (SOP) is to establish a systematic approach for validating analytical methods used in aerosol dosage forms to ensure accuracy, reliability, and compliance with regulatory standards.

2. Scope

This SOP applies to all analytical methods used in the Quality Control (QC) laboratory for the testing of aerosol formulations, including assay, content uniformity, spray performance, and impurity analysis.

3. Responsibilities

• Quality Control (QC) Analysts: Responsible for performing validation studies.
• Quality Assurance (QA) Team: Responsible for reviewing and approving validation protocols and reports.
• Laboratory Supervisor: Responsible for ensuring compliance with regulatory guidelines.
• Regulatory Affairs Team: Responsible for ensuring validated methods meet regulatory requirements.

4. Accountability

The Quality Control Manager is accountable for the validation of analytical methods and ensuring compliance with industry standards.

5. Procedure

5.1. Preparation of Validation Protocol

1. Define the analytical method to be validated.
2. Prepare a validation protocol covering accuracy, precision, linearity, specificity, and robustness.
3. Record validation protocol details in the Method Validation Protocol Log (Annexure-1).

5.2. Execution of Validation Studies

1. Conduct validation trials using representative aerosol formulations.
2. Perform triplicate analysis for each parameter.
3. Record experimental conditions in the Validation Study
