Standard Operating Procedure for Process Validation in Ocular Dosage Form Manufacturing

1) Purpose

The purpose of this SOP is to establish the procedure for conducting process validation to ensure that the manufacturing processes for ocular dosage forms, such as eye drops, ointments, gels, and inserts, consistently produce products meeting predetermined quality criteria.

2) Scope

This SOP applies to all manufacturing processes for ocular dosage forms within the pharmaceutical industry. It encompasses the validation of processes to demonstrate their consistency and reproducibility.

3) Responsibilities

QA Department: Responsible for approving validation protocols and reports.
Validation Team: Responsible for planning and executing process validation activities.
Production Department: Responsible for carrying out processes according to the validated methods.
Engineering Department: Responsible for ensuring equipment is maintained and calibrated.

4) Procedure

4.1 Preparation

1. Identify critical process parameters (CPPs) and critical quality attributes (CQAs) for the ocular dosage forms.
2. Develop a process validation protocol, including objectives, acceptance criteria, sampling plans, and analytical methods.
3. Ensure all equipment used is calibrated and maintained according to SOPs.

4.2 Execution

1. Conduct process validation runs under normal operating conditions.
2. Monitor and document process parameters and quality attributes during each validation run.
3. Collect samples at predefined stages for analysis.

4.3 Analysis

1. Analyze samples using validated analytical methods to assess the process performance and product quality.
2. Compare results against predefined acceptance criteria.

4.4 Documentation

1. Document all data, observations, and results in the process validation report.
2. Review and approve the process validation report.

4.5 Approval

1. Submit the process validation report to QA for approval.
2. Obtain final approval before commercial production begins.
