0 - 2 ug/mL

Interpretive Data

Effective 05/20/2014:

Reports show that in patients on divided daily dosage regimens, trough concentrations of  1–2  μg/mL  usually  ensure  that  the  concentration  is  above  the  MIC of most tobramycin-sensitive pathogens and that the drug elimination is adequate.  When patients are on a QD regimen, reports show that trough concentrations less than 1 μg/mL allow adequate clearance before the next dose.  Prolonged  trough  concentrations  above  2  μg/mL  are  often  associated  with  renal  impairment and ototoxicity.  For effective treatment, some patients may require serum or plasma levels outside these ranges. Therefore, the expected ranges are provided only as general guidance, and individual patient results should be interpreted in light of clinical signs and symptoms.  Troughs should be drawn immediately before the next dose.

 

Before 05/20/2014:

For Q8 dosing, peak levels should be 5-10 ug/mL and trough levels should be less than 2 ug/mL.
For QD dosingpeak levels are not necessary the majority of time, but should be greater than 8 ug/mL. Trough levels should be less than 1 ug/mL, with the level indicating a potential adjustment in dose if greater than 2 ug/mL

Trough should be drawn immediately before the nest dose. Peaks should be drawn 30 minutes after the end of a 30-60 minute aminoglycosdie infusion.
