1. Purpose

The purpose of this Standard Operating Procedure (SOP) is to define a structured process for validating manufacturing processes in ointment production. Process validation ensures that manufacturing activities consistently produce products that meet predefined quality standards and regulatory requirements.

2. Scope

This SOP applies to all personnel in the Production, Quality Assurance (QA), and Quality Control (QC) departments involved in the validation of manufacturing processes, including mixing, heating, filling, and packaging.

3. Responsibilities

• Production Operator: Performs manufacturing activities as per validated procedures.
• Production Supervisor: Ensures process parameters are followed and recorded.
• Quality Control (QC) Analyst: Conducts in-process and final product testing.
• Quality Assurance (QA) Officer: Reviews validation protocols, ensures compliance, and approves validation reports.
• Validation Team: Conducts process qualification studies and risk assessments.

4. Accountability

The QA Manager and Validation Team are accountable for ensuring that all manufacturing processes are validated and compliant with Good Manufacturing Practices (GMP).

5. Procedure

5.1 Validation Planning

• Define the scope, objectives, and responsibilities of process validation.
• Prepare a Validation Master Plan (VMP) outlining the validation approach.
• Identify critical process parameters (CPP) and critical quality attributes (CQA).
• Establish acceptance criteria for validation.

5.2 Process Design Qualification (DQ)

• Ensure that equipment and facilities meet GMP design requirements.
• Verify equipment installation, calibration, and maintenance records.
• Review raw material specifications and ensure compatibility with process design.

5.3 Process Performance Qualification (PQ)

• Conduct trial production runs under controlled conditions.
• Collect process data, including mixing time, temperature, and viscosity.
• Analyze process variability and consistency across multiple batches.

5.4 Process Validation Execution

5.4.1 Validation Batches

• Perform three consecutive full-scale manufacturing runs.
• Monitor and record in-process parameters at critical points.
• Ensure batch-to-batch consistency in product characteristics.

5.4.2 Analytical Testing

• Conduct active ingredient assay, pH testing, and microbial analysis.
• Ensure uniformity of dosage and absence of contamination.
• Compare results against predefined acceptance criteria.

5.4.3 Stability Studies

• Conduct accelerated and real-time stability testing.
• Monitor physical and chemical stability over time.
• Ensure product retains its intended quality throughout its shelf life.

5.5 Process Validation Report (PVR)

• Summarize validation findings and statistical analyses.
• Document deviations and corrective actions taken.
• Obtain QA approval before the manufacturing process is officially validated.

5.6 Continuous Process Verification

• Monitor validated processes periodically to detect potential variations.
• Implement corrective actions if deviations exceed acceptable limits.
• Revalidate processes as per regulatory guidelines or after significant process changes.
