AMINOGLYCOSIDES- RENAL DOSING

 

Guidelines (modified) of Sarubbi and Hull.

 

The first dose should be a modified loading dose equal to the maintenance dose in a subject with normal renal function:  Loading dose: 1.5-2.0 mg/kg (gentamicin, netilmicin, sisomicin, tobramycin).  Loading dose: 5-7.5 mg/kg (amikacin, kanamycin, streptomycin).

Hemodialysis: 1/2 initial dose as a supplement at the end of dialysis
