A media-fill test (MFT) validated sterile cytotoxic drug preparation processes inside and outside isolators. The study confirmed facility compliance with sterility standards, emphasizing decontamination protocols for safe compounding.
Area of Science:
- Pharmaceutical Compounding
- Sterile Product Manufacturing
- Hospital Pharmacy Operations
Background:
- Cytotoxic drug preparation requires stringent aseptic techniques to prevent contamination.
- Media-fill testing (MFT) is crucial for validating sterile compounding processes.
- French compendial standards mandate verification of cytotoxic drug preparation procedures.
Purpose of the Study:
- To validate cytotoxic drug preparation processes within and outside aseptic compounding isolators.
- To assess the efficacy of decontamination and sterile compounding procedures.
- To evaluate the performance of isolator operators during MFT.
Main Methods:
- An MFT protocol was adapted to hospital-specific conditions.
- 12 isolator operators each produced 30 MFT samples over three testing occasions.
- Alternative compounding systems were tested for emergency use; all MFTs used tryptone soy broth under worst-case conditions.
Main Results:
- All 360 MFT samples produced by isolator operators met sterility standards.
- The hospital's cytotoxic drug preparation facilities were in conformance with sterility standards.
- One MFT sample using a closed-system transfer device showed contamination due to improper vial cleaning, stressing decontamination importance.
Conclusions:
- The hospital's sterile product preparation practices, including emergency procedures, were validated by MFT.
- The study confirmed the reliability of aseptic compounding isolators for cytotoxic drug preparation.
- Adherence to decontamination protocols is critical for maintaining sterility in pharmaceutical compounding.
