Ceftriaxone plus amikacin in a single daily dose as empiric antibiotic therapy in granulocytopenic patients.

ABSTRACT

In our study ceftriaxone plus amikacin were employed as empirical antibiotic therapy. This antibiotic treatment allows for a once daily administration and has a broad spectrum of activity. 21 febrile episodes were treated with an antibiotic regimen of ceftriaxone 50 mg/kg/day and amikacin 30-35 mg/kg/day i.v. An earlier pilot study was carried out in which 47 febrile episodes were treated with an antibiotic regimen of ceftriaxone 80-100 mg/kg/day i.v. and amikacin 30-35 mg/kg/day i.v. in a single dose. The overall response rate was 76% (16/21) and 79% (37/47) for the pilot study. During the treatment no side effects were observed and aminoglycoside related toxicity did not occur. In conclusion, this empiric antibiotic therapy gives a high response rate and allows for a single daily administration.
