Standard Operating Procedure for Eye Drop Mixing System in Ocular Dosage Form Manufacturing
1) Purpose
The purpose of this SOP is to establish a standardized procedure for the operation, cleaning, and maintenance of the eye drop mixing system to ensure uniform and consistent mixing of eye drops for ocular dosage forms.
2) Scope
This SOP applies to all eye drop mixing systems used in the manufacturing of ocular dosage forms within the pharmaceutical manufacturing facility.
3) Responsibilities
Production personnel are responsible for operating the eye drop mixing system and maintaining accurate records. Quality control personnel are responsible for verifying the mixing process and ensuring compliance with SOPs.
4) Procedure
4.1 Preparation for Eye Drop Mixing
- Ensure the mixing area is clean, organized, and free from contaminants.
- Verify the availability and condition of all equipment, utensils, and materials needed for the mixing process.
- Calibrate the eye drop mixing system according to the manufacturer’s instructions to ensure proper mixing parameters.
- Record the batch number, product name, and quantity of eye drops to be mixed in the batch production log.
4.2 Eye Drop Mixing Process
- Preparation of Mixing Equipment
- Assemble the mixing system components as per the manufacturer’s instructions.
- Sanitize all parts that come into contact with the eye drops using appropriate disinfectants.
- Set up
- Load the eye drop ingredients into the mixing system hopper or reservoir.
- Start the mixing system and begin the mixing process.
- Monitor the mixing process to ensure uniform and consistent mixing of the eye drops.
- Perform in-process checks for mix uniformity and consistency at regular intervals.
- Take samples of the mixed eye drops for quality control testing, including uniformity and consistency.
- Record the results of the quality control tests in the batch production log.
- If any parameters are out of specification, investigate and take corrective actions before proceeding.
- Transfer the mixed eye drops to the designated containers for storage or further processing.
- Label the containers with the batch number, product name, and other required information.
- Store the containers in a designated area under controlled conditions.
4.3 Cleaning and Maintenance
- Clean the eye drop mixing system and all associated equipment thoroughly after each batch according to the cleaning SOP.
- Inspect the system for any signs of wear or damage and perform necessary maintenance or repairs.
- Record all cleaning and maintenance activities in the equipment logbook.
4.4 Documentation
- Record the details of the eye drop mixing process, including mixing parameters, in-process checks, and quality control results, in the batch production log.
- Ensure that all records are signed and dated by the personnel responsible for the mixing.
- Attach a copy of the batch production log to the batch production record for traceability.
4.5 Review and Approval
- The quality assurance department should regularly review mixing procedures and records to ensure compliance with SOPs and regulatory requirements.
- Any discrepancies or deviations should be investigated, documented, and resolved promptly.
- Review and update the SOP as necessary to reflect any changes in procedures, regulations, or industry standards.
