Dosing Weight Calculations

Ideal Body Weight (Devine Formula)

Male: IBW = 50 + 2.3 x (height in inches - 60) Female: IBW = 45.5 + 2.3 x (height in inches - 60)

Adjusted Body Weight

AdjBW = IBW + 0.4 x (Actual Weight - IBW)

Adjusted body weight is used for drug dosing in obese patients (>20% above IBW) because many drugs do not distribute fully into adipose tissue.

Ejemplo Resuelto

A 70-inch tall male weighing 110 kg.

  1. IBW = 50 + 2.3 x (70 - 60) = 73 kg
  2. AdjBW = 73 + 0.4 x (110 - 73) = 73 + 14.8 = 87.8 kg
  3. Percent over IBW = (110 - 73) / 73 x 100 = 51%
