Tobramycin Extended-Interval Dosing Calculator

Calculate tobramycin extended-interval dosing (5-7 mg/kg q24-48h) based on creatinine clearance to maximize peak bactericidal activity while minimizing cumulative nephrotoxicity in gram-negative infections.

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

Calculate tobramycin extended-interval dosing (5-7 mg/kg q24-48h) based on creatinine clearance to maximize peak bactericidal activity while minimizing cumulative nephrotoxicity in gram-negative infections

Each component has a specific meaning:

  • Creatinine clearance — The creatinine clearance recorded for the scenario being assessed.

Note: Interpret the tobramycin extended result against the thresholds and context described above.

How to Use

Enter the creatinine clearance for the scenario you are assessing. Calculate tobramycin extended-interval dosing (5-7 mg/kg q24-48h) based on creatinine clearance to maximize peak bactericidal activity while minimizing cumulative nephrotoxicity in gram-negative infections. Use the tobramycin extended result to inform your calculation.
