Carboplatin AUC Dose for Male (mg) - Carboplatin AUC Dose for Male (mg) is used for calculating the dose based upon a patient's glomerular filtration rate and carboplatin target area under the concentration versus time curve. It is indeed accurate and precise, yet remains complex and inaccessible for a vast majority. GFR was measured by 51Cr-EDTA clearance. The maximum dose is based on a GFR estimate that is capped at 125 mL/min for patients with normal renal function. For Study 1, GFR was determined using the plasma CL of 51 Cr-EDTA. Carboplatin dosage using eGFR was significantly lower than the dosage calculated with the other formulae (p<0.01). The same argument would probably also hold true for the newer model proposed by Janowitzet al. Ann Pharmacother. Renal function using eGFR was lower than renal function calculated by using the other formulae. Dosage calculated by CockcroftGault-based GFR and manufacturer's recommendation had significant variation as compared to the authors' new equation-based carboplatin dose [Table 1]. carboplatin auc dose for male calculator uses carboplatin auc dose for male (mg) = target auc* (gfr for male (ml/min)+25) to calculate the carboplatin auc dose for male (mg), carboplatin auc dose for male is used for calculating the dose based upon a patient's glomerular filtration rate and carboplatin target area under the concentration versus Here is how the Carboplatin AUC Dose for Male calculation can be explained with given input values -> 6.000E+8 = 5*(95+25).
