Standard Operating Procedure for Blending Process
Purpose:
The purpose of this SOP is to provide guidelines for the blending process within the tablet manufacturing department. This SOP aims to ensure the proper blending of raw materials and excipients, adherence to dosage specifications, and compliance with regulatory requirements and Good Manufacturing Practices (GMP).
Scope:
This SOP applies to all personnel involved in the blending process in the tablet manufacturing department.
Responsibilities:
3.1. Production Supervisor:
Ensure that blending operators are trained and qualified to perform the tasks outlined in this SOP.
Verify that blending operations are carried out in accordance with the defined procedures.
Monitor compliance with safety regulations and GMP during blending operations.
3.2. Blending Operator:
Perform blending operations as per the documented procedures.
Follow safety guidelines and wear appropriate personal protective equipment (PPE) during blending operations.
Report any abnormalities, equipment malfunctions, or quality issues to the Production Supervisor.
Procedure:
4.1. Pre-Blending Preparations:
a. Gather the necessary raw materials, excipients, and blending equipment required for the blending process.
b. Verify that all raw materials and excipients are properly labeled and correspond to the batch record.
c. Ensure that the blending equipment is clean, properly assembled, and in good working condition.
4.2. Blending Process:
a. Review the batch record and verify the blending parameters, including blending time, speed, and load capacity.
b. Set the blending equipment controls as per the specified parameters in the batch record.
c. Load the required raw materials and excipients into the blending equipment as per the batch record instructions.
d. Close and secure the blending equipment, ensuring that all access points are properly sealed.
e. Start the blending equipment and monitor the blending process to ensure uniform mixing.
f. Perform in-process checks, such as blend uniformity testing or sampling, as specified in the batch record.
g. Document all relevant information and observations in the batch record and logbooks.
4.3. Post-Blending Cleaning:
a. Once the blending process is complete, stop the blending equipment and ensure it is locked out.
b. Disassemble and remove all removable parts from the blending equipment, such as blending chambers or paddles.
c. Clean the disassembled parts and equipment surfaces using approved cleaning agents and procedures.
d. Rinse all parts and equipment surfaces with clean water to remove any residue of cleaning agents.
e. Dry the cleaned parts and equipment surfaces using lint-free wipes or air compressors.
f. Reassemble the cleaned parts in their appropriate positions, ensuring proper alignment and tightening of fasteners.
