Design of Analytical Method Validation Protocol Evaluating Environmental Monitoring of AND Contamination on Surfaces...

Environmental monitoring of anti-neoplastic drug (AND) residues in workplaces is crucial to limit exposure to workers who handle with them. Although wipe sampling is the most appropriate methodology to evaluate the risk, conflicting results are also reported due to the lack of standardized and validated procedures. In this study, procedures for surface contamination of ANDs in workplaces are presented, with a focus on sampling, sample preparation and instrumentation. The analytical method validation parameters are designed to comply with requirements of The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) Q7 Good Manufacturing Practice (GMP) for active pharmaceutical ingredients. Additionally, the study provides a simple, specific, rapid and multi-component analytical method to evaluate seven ANDs that are Gefitinib, Imatinib, Dasatinib, Axitinib, Erlotinib, Nilotinib and Sorafenib at very low concentration levels, simultaneously. Quantitative, precise and reproducible results obtained from the study show that environmental monitoring procedure and analytical method validation protocol presented in the study can be used to reduce and monitor occupational exposure risk to ANDs in wokplaces.
