Abstract: People live in the mountains distributed across the world and are exposed to reduced inspired oxygen and lower barometric pressure along with other factors that lead to high-altitude diseases. The present study was conducted to examine what extent of marketed medicines used in the management of high-altitude sickness has been tested for their genotoxic activity. Comet assay or the single-cell gel electrophoresis was utilized to evaluate genotoxicity of the six medicines on human peripheral whole blood cells and isolated lymphocytes at the concentrations 250 microg/mL, 500 microg/mL and 1 mg/mL. The comet assay endpoints included percentage Tail DNA (% Tail DNA) and olive tail moment (OTM) as they were considered to be sensitive and reliable scores across different laboratories. The results show that dexamethasone, deriphylline and furosemide can induce significant DNA damage in human whole blood and lymphocytes alike. Acetazolamide, ibuprofen and nifedipine show no genotoxic effect, neither on human whole blood nor on human lymphocytes. Taking into account the results of genotoxicity, it will be a prudent choice to restrict the use of these compounds for longer periods, until more information on the in vitro mutagenicity and in vivo genotoxicity studies are available.
