Study Notes
Quality Control Department Responsibilities
- Ensures that only drugs of the highest quality are marketed
- Works closely with the Production department to achieve this goal
- Establishes and authorizes specifications and instructions for all stages of production
- Inspects, jointly with the Production department, to verify that instructions are followed effectively
- Makes decisions regarding the use of materials and the release of finished products
Quality Control Processes
-
Specifications for Raw Materials and Finished Products:
- Define the quality standards for materials and products
- Often based on pharmacopoeia monographs
- Detailed instructions are needed for sampling and analysis
-
Storage Instructions:
- Established for starting materials, intermediates, and finished products
- Must be aligned with stability studies to ensure product quality over time
- Include expiry dates for all materials and products
-
In-Process Controls:
- Essential for assessing the quality of finished products
- Require specific instructions to ensure proper monitoring and control throughout the production process
Quality Control Manager's Role
-
Laboratory Responsibilities:
- Responsible for a well-equipped laboratory
- Analytical and microbiological testing of raw materials and finished products
- Analysis of in-process samples
-
Release Authority:
- Ultimate authority to release raw materials for production
- Decides on the release of finished products for sale
- Decisions based on analytical and microbiological test results, in-process control data, and production observations
Challenges and Solutions
-
Potential Friction with Production Department:
- "Monitoring of the Q.C aspects of manufacturing operations" can be seen as an infringement
- Inspections and sampling can cause tension
-
Solutions:
- Clear communication and collaboration are crucial
- Dedicated inspection areas in production facilities, especially for sterile products
- Well-equipped laboratory with experienced staff
Microbiological Control
-
Increasing Importance:
- Ensures environmental control and microbiological purity
- Essential for testing raw materials, intermediates, and finished products
-
Pharmacopoeia Requirements:
- Prescribes limits for total viable count
- Some specific microorganisms should be completely absent (e.g., Salmonella in oral preparations, Pseudomonas aeruginosa in ointments)
-
Test for Enterobacteria:
- Useful indicator of hygienic production conditions
Outsource Testing
-
Option for Specialized Tests:
- Laboratory may outsource certain tests if they lack the necessary facilities
-
Manufacturer's Responsibility:
- The manufacturer remains responsible for product quality
- Must ensure that the outsourced laboratory is adequately equipped and qualified
