The invisible danger lurking in manual drug compounding
In short: While pharmacists use precision to create custom medicines, a hidden risk remains. Recent studies show that manual preparation of cytotoxic drugs leaves significant chemical residues on gloves and surfaces, creating an occupational exposure risk that extends far beyond the initial compounding stage.
Compounding is the art of preparing customized medications to meet unique patient needs, such as adjusting doses for infants or removing allergens. While hospital pharmacies often handle sterile intravenous preparations, the process involves handling potent substances like cyclophosphamide and fluorouracil. A recent experimental study compared manual compounding to the use of an intravenous compounding robot to measure the spread of drug residues.
The findings revealed a stark difference in safety. In manual compounding groups, researchers detected extreme residue values, such as fluorouracil on gloves reaching 834.340 ng/cm². Crucially, the risk is not contained to the preparation site; residues were also found on packaging and administration bags in manual groups, with fluorouracil levels reaching up to 734.704 ng/cm². This indicates that exposure risks persist through the entire workflow, including transport and nursing.
Human behavior also plays a role in this safety gap. A survey of cytotoxic drug handlers showed that while 100% recognized the risk of occupational exposure, adherence to protective measures varied. While compounding staff strictly followed protocols, only 45.5% of nurses always wore gloves during administration, and significant numbers of packaging and transport workers lacked gloves entirely.
Although using a robot significantly lowered drug traces on protective gear, researchers found that one post-sanitisation reading of 0.018 ng/cm² within the machine indicates slight gaps in the cleaning process. Although the risk of cross-contamination when switching to non-cytotoxic drugs appeared low, researchers noted they cannot yet directly translate these residue values into specific cancer risks for staff, meaning further validation is required.
