Standard Operating Procedure for Process Validation in Ocular Dosage Form Manufacturing

1) Purpose

The purpose of this SOP is to define the procedures for process validation to ensure that manufacturing processes for ocular dosage forms consistently produce products that meet predetermined quality and performance criteria.

2) Scope

This SOP applies to all processes involved in the manufacturing of ocular dosage forms, including eye drops, ointments, gels, and inserts. It encompasses the validation of processes to demonstrate that they operate effectively and reproducibly.

3) Responsibilities

The Quality Assurance (QA) department is responsible for overseeing process validation activities. Production personnel are responsible for executing the processes as per approved protocols. The Validation team develops and validates the processes, ensuring compliance with regulatory requirements.

4) Procedure

4.1 Process Validation Protocol Development

1. Identify critical process parameters (CPPs) and critical quality attributes (CQAs) that impact product quality.
2. Develop process validation protocols specifying validation objectives, acceptance criteria, sampling plans, and analytical methods.
3. Include a detailed description of the process, equipment, and materials used in the manufacturing of ocular dosage forms.

4.2 Process Validation Execution

1. Conduct process validation studies under defined conditions using approved protocols.
2. Monitor and record process parameters and quality attributes at each stage of the manufacturing process.
3. Collect samples for analysis according to the process validation protocol.

4.3 Analytical Testing and Evaluation

1. Analyze samples using validated analytical methods to assess process performance and product quality.
2. Compare results against established acceptance criteria to determine process consistency and reproducibility.
3. Document and evaluate process validation data, including deviations and corrective actions.

4.4 Process Validation Report

1. Compile process validation results and conclusions into a comprehensive report.
2. Include details of process parameters, sampling methods, analytical results, and compliance status.
3. Obtain approval from QA for the process validation report before commercial production commences.
