Spill and leakage using a drug preparation system based on double-filter technology

Area of Science:

• Pharmaceutical Technology
• Occupational Health and Safety
• Drug Delivery Systems

Background:

• Occupational exposure to cytotoxic drugs is a significant concern in healthcare settings.
• Various drug-handling systems aim to minimize spills and leakage during preparation.
• Independent testing methods are crucial for evaluating the efficacy of these systems.

Purpose of the Study:

• To evaluate the spill and leakage performance of the Tevadaptor drug-handling system during cytotoxic drug preparation.
• To compare the Tevadaptor system's performance against established drug-handling systems and closed systems.
• To assess the safety and reliability of the Tevadaptor system in reducing occupational exposure.

Main Methods:

• A modified Technetium test method using Technetium-99m as a tracer substance was employed.
• The Tevadaptor system was tested across 75 drug preparations.
• Spill and leakage quantities were meticulously measured for each preparation.

Main Results:

• The Tevadaptor system demonstrated minimal spill, with all preparations showing less than 100 nl.
• Seventy out of 75 preparations exhibited spills of less than 1 nl.
• Performance was comparable to other tested systems like isolators and PhaSeal.

Conclusions:

• The Tevadaptor drug-handling system exhibits excellent performance in minimizing cytotoxic drug spills.
• Its efficacy is comparable to existing drug-handling systems considered closed systems.
• The Tevadaptor system offers a viable solution for reducing occupational exposure to hazardous drugs.
