1. Purpose
To define the standardized approach for planning, executing, and documenting cleaning validation of equipment used in the Elixir Department to demonstrate the effectiveness and consistency of cleaning procedures, and ensure compliance with GMP, ICH, and regulatory requirements.
2. Scope
This SOP applies to all product-contact equipment and accessories used in the manufacturing of elixirs, including mixing vessels, transfer lines, pumps, storage tanks, and filling lines that require cleaning validation due to product changeover or routine cleaning.
3. Responsibilities
- Validation Team:
- Design validation protocols and perform sampling and testing activities.
- Production Department:
- Support execution of cleaning as per the validated method and assist in equipment availability.
- Quality Control (QC):
- Analyze samples for residuals, microbial contamination, and carryover limits.
- QA Department:
- Approve cleaning validation protocols, review reports, and ensure GMP compliance.
4. Accountability
The Head of Quality Assurance is accountable for the final review
and approval of cleaning validation activities and ensuring regulatory alignment.
5. Procedure
5.1 Cleaning Validation Lifecycle
- Cleaning validation shall follow a lifecycle approach including:
- Design (protocol preparation)
- Execution (sampling and analysis)
- Review (data assessment and conclusions)
- Revalidation (as per defined frequency or change)
5.2 Protocol Preparation
- Prepare a Cleaning Validation Protocol with the following details:
- Objective and scope
- Equipment details
- Worst-case product selection rationale
- Cleaning procedure description
- Sampling locations and method (swab/rinse)
- Acceptance criteria
- Sampling and analysis methodology
- Number of cleaning runs (minimum three consecutive batches)
5.3 Execution of Cleaning Process
- Perform cleaning of equipment as per the established SOP using validated cleaning agents.
- Ensure no visible residue remains on equipment surface post cleaning.
- Maintain equipment status labels as “CLEANED.”
5.4 Sampling Procedure
- Perform swab sampling at predetermined locations using validated swabs and solvents.
- Perform rinse sampling by collecting rinse water from cleaned equipment surfaces.
- Label and transport samples under controlled conditions to QC for analysis.
5.5 Analytical Testing
- Analyze swab/rinse samples for:
- Product residue (e.g., API, excipients)
- Cleaning agent residue
- Microbial contamination (if required)
- Record results in Cleaning Validation Data Sheet (Annexure-1).
5.6 Acceptance Criteria
- Residue limit should be below the Maximum Allowable Carryover (MACO).
- No visible residue on equipment surface.
- Microbial limits within specifications (if applicable).
5.7 Report Preparation
- Compile results into a Cleaning Validation Report including:
- Summary of cleaning procedures
- Sample locations and analytical results
- Deviations observed and their investigation
- Conclusion on cleaning effectiveness
- Submit to QA for final approval and archiving.
5.8 Revalidation Criteria
- Revalidation is required if:
- Cleaning SOP is changed
- Product or process changes occur
- Equipment is modified or replaced
- Failure or deviation in cleaning procedure is reported
