Aminoglycosides are excreted primarily by glomerular filtration, thus, the serum half-life will be prolonged and significant accumulation will occur in patients with impaired renal function.
Peak: 20.0-35.0 mcg/mL
Toxic peak: >40.0 mcg/mL
Trough: <8.0 mcg/mL
Toxic trough:>10.0 mcg/mL
For conventional (nonpulse) dosing protocols, clinical effects may not be achieved if the peak serum concentration is <20.0 mcg/mL. Toxicity may occur if, for prolonged periods of time, peak serum concentrations are maintained >35.0 mcg/mL, or trough concentrations are maintained at >10.0 mcg/mL.
