- Once-daily dosing of amikacin is a novel therapy regimen which seems pharmacokinetically appropriate for the primary group of patients considered for aminoglycoside therapy. In this study of 29 elderly patients with serious infections, amikacin 11 mg/kg or 15 mg/kg bw was administered as a short-term (30 min) intravenous infusion. The amikacin serum concentration-time profile was best described by a bi-exponential equation with a half-life of about 4.8 h. A triexponential equation was not applicable because the slow terminal elimination phase was not detected during the 24 h dosing interval. In practice, a uni-exponential equation is often used, and this may lead to incorrect conclusions about the elimination rate of amikacin. Amikacin clearance provides more direct information about elimination of amikacin than does serum half-life. Thus, there was a better correlation between the individual amikacin clearances and creatinine clearances (r = 0.89), than between the serum half-lives of amikacin and the creatinine clearances (r = 0.71). For elderly patients a smaller dose of amikacin than the regular daily dose of 15 mg/kg bw, i.e. about 11 mg/kg bw, seems recommendable, when it is given once daily. From the data obtained it is also obvious that once-daily dosing of amikacin does not eliminate the need for checking serum concentrations of the drug.
