Study Notes
Aseptic Operation and Environment
-
Aseptic operation and environment are crucial for producing sterile pharmaceuticals.
-
Learning outcomes include describing the theory of aseptic products, the implications of non-sterility in aseptic manufacturing, and the key components of aseptic processing.
-
Cleanliness is essential, encompassing health and safety, storage, and application. Hand washing is crucial for preventing contamination.
-
Different levels of cleanliness are defined, ranging from clean to sterile. Sterility is the complete destruction or elimination of all viable microorganisms.
-
Sterilization does not always completely destroy all infectious matter.
-
Problems with the definition of sterility include isolating and detecting all microorganisms, different inactivation rates, and the impracticality of guaranteeing product sterility mathematically.
-
Sterility assurance level (SAL) is a statistical probability used to measure the sterility of a product. An SAL of 10-6 suggests one non-sterile item per million.
-
Pharmaceutical products requiring a high SAL (10-6 or higher) include those contacting breached or compromised tissue, invasive products, and those claiming sterile fluid pathways.
-
Products not expected to contact compromised tissue, including topical medications, require a lower SAL (10-3 or higher).
-
Non-sterile products are permitted to contain viable microorganisms, with maximum concentrations defined by PhEur.
-
Sterile pharmaceutical products need complete sterility, including parenteral products (IV infusions), noninjectable sterile fluids, ophthalmic preparations, dressings, and implants.
-
"Parenteral" comes from Greek words, "par" (avoid) and "enteral" (alimentary canal). It avoids the body's protective barriers.
-
Aseptic preparation techniques include drawing up medications and making infusion bags, including intravenous antibiotics. This ensures safety for patients and staff.
-
Cytotoxic drugs (e.g., Chemotherapy) are prepared within aseptic areas for patient safety. This limits direct exposure to ward staff.
-
Implication of a sterile product becoming contaminated can lead to product recall, product spoilage, or death. Causes can be microbial contamination (viable organisms) or contamination by non-viable contaminants (e.g., particles, chemicals).
-
Issues and incidents that highlight the need for aseptic procedures include the Devonport incident (1971-2) involving faulty autoclaving, the Manchester incident (1994) involving contaminated TPN, the Romaira incident (1996) linked to locally produced IV solutions, and contaminated heparin IV flushes (2005).
-
Product recalls, due to contamination, also emphasize the importance of aseptic procedures.
-
Product spoilage can arise from the breakdown of the active pharmaceutical ingredient (API), formulation breakdown, reduced acceptability (to patient) due to spoilage, and degradation of the preservative.
-
Problems within pharmacy aseptic units, such as background issues, the UK National Aseptic Error Reporting Scheme (NAERS), error types (incorrect containers, drug, diluent, dose, labeling, etc.).
-
Staff-related error causation (workload, training, distraction).
-
Product-related error causation (based on product types).
-
Potential outcomes for aseptic procedure failures (catastrophic, major, moderate, minor, none).
-
Aseptic procedure fundamentals include a cleanroom, sterile equipment, personnel training, and procedures for moving around the room.
-
Equipment (laminar flow cabinets and their role of HEPA filters).
-
Process verification and control (equipment verification, procedures, etc.).
-
Personnel practices (gowning, hair covering).
-
Cleanroom classification (ISO 5, 7, and 8).
-
Clean air separation (positive differential pressure and HEPA filters).
-
Laminar flow cabinets (airflow, critical areas).
-
Monitoring of physical parameters (airflow velocity, differential pressure, particulate matter, temperature, humidity).
-
Monitoring of microbial contamination(contact plates, swabs, active air samples).
-
Frequency of microbial sampling and testing, and reporting.
-
Aseptic areas are critical for preparing sterile products but require high levels of maintenance, quality control, expertise, and staff training.
-
Recommended reading includes specific pharmaceutical texts for further study.
