“Leukerin® powder 10%” containing mercaptopurine (6-MP) is an oral anticancer drug that requires careful handling. As a powder formulation, there are risks of exposure due to scattering during dispensing and possible 6-MP contamination to other drugs due to adhesion to the packaging machine. We previously reported that wiping with an alcohol-containing towel is useful for removing scattered powder after dispensing. However, it is recommended to wipe disk-type powder-packaging machines with water instead of cleaning with the alcohol-containing towel. Hence, we scattered 6-MP powder 100 mg (total amount of 6-MP: 10 mg), and then wiped with water three times using different types of cloth each time. We confirmed that third time wiping cloth did not have any 6-MP. Furthermore, we confirmed that the adhering 6-MP could be removed by wipe-cleaning (water-wiping twice and dry-wiping once) after dispensing 6-MP powder at two pharmacies that routinely dispensed 6-MP powder using a disk-type powder-packaging machine. In addition, we confirmed the adhesion of 6-MP in parts of the machine not cleaned by wipe-cleaning and also in parts that were washed only with water, in both the pharmacies. Based on the above observations, we recommend the following steps for cleaning disk-type powder-packaging machines after dispensing 6-MP powder: (1) wipe-cleaning that includes water-wiping twice and then dry-wiping once, (2) cleaning all areas of the packaging machine, and (3) wipe-cleaning with water before washing with water.
