Estimated Creatinine Clearance (CrCl)

Cockcroft-Gault equation (N = 1.23 males, 1.03 females):

CrCl (ml/mn) = N x [140 - age (years)] x Wt (kg)

Ideal Body Weight (IBW)

IBW (kg) ♂ = 50 kg + 1 kg per cm over 152 cm
IBW (kg) ♀ = 45.5 kg + 1 kg per cm over 152 cm

Obese Dosing Weight (ODW) - for gentamicin/amikacin

Use ODW for dose calculations if actual weight > 120% IBW:

ODW (kg) = IBW + 0.4 (actual weight - IBW)
