One Shot of High-Dose Amikacin: A Working Hypothesis

Abstract
Recent information suggests that single, large daily dosages of amikacin are less nephrotoxic. The killing rate of amikacin for Escherichia coli and Pseudomonas aeruginosa also suggests to put emphasis on a high peak value. A decrease of 3 logio CFU/ml was observed for E. coli and P. aeruginosa at 64 and 128 (ig/ml in 20 min. In comparison, the killing rate of piperacillin was dose-independent and about 6 h were required for a reduction of 103 CFU/ml of P. aeruginosa. In theory, the way to proceed in the future would possibly be the one-shot administration of amikacin, followed by a long course of a β-lactam antibiotic.
