Aminoglycoside Once-Daily Dosing and Extended-Interval Calculator

Calculates gentamicin/tobramycin/amikacin extended-interval dosing using the Hartford nomogram, renal function-adjusted interval, and draws for peak-trough monitoring in conventional dosing.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculates gentamicin/tobramycin/amikacin extended-interval dosing using the Hartford nomogram, renal function-adjusted interval, and draws for peak-trough monitoring in conventional dosing

Each component has a specific meaning:

  • Hartford nomogram — The hartford nomogram recorded for the scenario being assessed.
  • Renal function-adjusted interval — The renal function-adjusted interval recorded for the scenario being assessed.
  • Draws — The draws recorded for the scenario being assessed.

Note: Interpret the aminoglycoside dosing result against the thresholds and context described above.

How to Use

Enter the Hartford nomogram, renal function-adjusted interval, draws for the scenario you are assessing. Calculates gentamicin/tobramycin/amikacin extended-interval dosing using the Hartford nomogram, renal function-adjusted interval, and draws for peak-trough monitoring in conventional dosing. Use the aminoglycoside dosing result to inform your calculation.
