TIP

Cockcroft-Gault uses actual body weight. For obese patients, some institutions use adjusted body weight. The formula estimates GFR and is most commonly used for drug dosing adjustments. Common drugs requiring renal adjustment: vancomycin, enoxaparin, metformin, gabapentin, and aminoglycosides.
