Cockcroft-Gault formula

A calculation used to estimate creatinine clearance based on age, weight, serum creatinine, and gender. Estimated creatinine clearance may be used to adjust dosages of renally excreted drugs. This formula is commonly used to adjust dosages for adult patients because their serum creatinine level may be a poor indicator of renal function. Because of decreased muscle mass in elderly patients, the serum creatinine level is a poor indicator of renal function; therefore this formula is used to adjust dosages. For men the formula is (140 – age) (weight in kg)/ 72 × serum creatinine. For women, this result is multiplied by the factor 0.85.

A commonly used clinical estimation of renal function is based upon serum creatinine level as a surrogate marker, applying the Cockcroft-Gault formula.
The substudy analysis calculated estimated glomerular filtration rates (eGFR) for patients enrolled in ARISTOTLE by three difference methods: the Cockcroft-Gault formula, the Chronic Kidney Disease-Epidemiology Collaboration formula, and cystatin C measurement.
Reduced renal function can also be assessed with creatinine-based formulae such as the Cockcroft-Gault formula (5), which calculates creatinine clearance rate in mL/min, or the Modification of Diet in Renal Disease (MDRD) [5] formula, which calculates glomerular filtration rate in mL/min/1.
Patients in the Prograf group exhibited higher estimated creatinine clearance rates (eCLcr) using the Cockcroft-Gault formula and experienced fewer efficacy failures, defined as biopsy proven acute rejection (BPAR), graft loss, death and/or lost to follow-up in comparison to each of the other three groups: Prograf/MMF (20.
