A study of amikacin given once versus twice daily in serious infections.

Author information

Department of Infectious Diseases, University Hospital, Linköping, Sweden.


Forty-five mostly elderly patients with serious infections were treated in a prospective, comparative and randomized pharmacokinetic study with amikacin 11.0 or 15.0 mg/kg administered in a single daily dose as an intravenous, short-term infusion or with amikacin 7.5 mg/kg administered twice daily in the same way. The results indicate that administration of amikacin 15 mg/kg in a single daily dose should be a practical and safe principle of administration. However elderly patients often have reduced creatinine clearance and should preferably be given a lower dose of 11 mg/kg bw. The risk of nephrotoxicity did not increase, but conclusions on ototoxicity and clinical efficacy cannot be drawn from this limited study. This should be considered as an initial part of a future multicentre trial.
