This information is not intended to replace clinical judgment or guide individual patient care in any manner. Dosages of drugs cleared renally should be adjusted according to creatinine clearance or glomerular filtration rate and should be calculated using online or electronic calculators. Estimations of GFR are frequently used in clinical practice, however, several important points should be reviewed (see below). This formula appears to have better performance characteristics when used in patients with preserved renal function, though further validation is ongoing. Click here for full notice and disclaimer. Stage 2: Mild reduction in GFR (60-89 mL/min/1.73 m 2) 3. Knowing your glomerular filtration rate (GFR) will help you understand how well your kidneys are functioning. It uses creatinine clearance (GFR) and target area under curve for the dose estimation. Stage 3a: Moderate reduction in GFR (45-59 mL/min/1.73 m 2) 4.

Stage 4: Severe reduction in GFR (15-29 mL/min/1.73 m 2) 6. A drug used to treat cancer is the carboplatin. The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation was developed as a follow-up to the MDRD equation in an attempt to be as accurate in describing renal function at lower GFR (less than 60 mL/min/1.73 m 2), but more accurate at a higher GFR.The CKD-EPI equation was developed and validated retrospectively in 8,254 patients from 10 studies. It is likely to be more accurate than this calculator, which cannot take into account local variations in creatinine measurements.
