AimZZRobots are able to increase safety for pharmacy staff as separating from toxicity of anti-cancer drugs. For patient safety, it would provide right dose of the drugs. Additionally, it can reduce price of the drugs. Therefore, in this study, a novel compounding anticancer drugs robot system (Dupalro) was developed. MethodsZZWe used the robot system, Motoman dual-arm robot from YASKAWA, Japan and medications which are adapted for the robot were constructed. In order to develop a process of compounding anticancer drugs, information about five medications that are required to make anticancer drugs in hospitals was used. ResultsZZSystem for the five types of medications was constructed, and relating procedures for anticancer drugs compounding robot were developed. ConclusionZZDupalro successfully was able to not only provide incremental safety and efficiency for both patients and pharmacy staff, but also decrease price of anticancer drugs.Key WordsZZDupalro ㆍMedication ㆍAnticancer drugs ㆍSafety ㆍAutomatic robot ㆍCompounding ㆍPharmacists.
