The Cockcroft-Gault equation, developed in 1976, estimates creatinine clearance (CrCl) using age, weight, and serum creatinine. Although eGFR (CKD-EPI) is superior for staging kidney disease, Cockcroft-Gault remains deeply entrenched in clinical practice because the vast majority of historical pharmacokinetic studies for drug dosing (e.g., DOACs, antibiotics) were based on this specific formula.
In obese patients, using actual body weight artificially inflates the creatinine clearance, potentially leading to toxic drug overdoses. Always use Adjusted Body Weight (AdjBW) or Ideal Body Weight (IBW) for patients whose BMI indicates significant obesity.
