To use this online calculator for Carboplatin AUC Dose for Female, enter Target AUC (AUC) & GFR for female (mL/min) (GFR) and hit the calculate button. min gave rise to manageable hematological toxicity in previously treated and untreated patients, respectively, and hence target AUC values of 5 and 7 mg/mL min are recommended for single-agent carboplatin in these patient groups. Kidney function should not be capped at 125 mL/min for use in the Calvert formula. Carboplasm will be administered 1 hour prior to the gemcitabine infusion, bevacizumab will be administered 1 hour following chemotherapy infusion. This treatment is followed by adjuvant chemotherapy consisting of CARBOplatin at AUC 5 intravenously and 5-FU infusion at 1000 mg/m2/day by 96h infusion every 4 weeks for a total of three cycles, beginning 4 weeks after the end of radiation therapy. This formula has also been used in patients with end-stage renal disease on hemodialysis by assuming that the GFR is zero.

AUC = target area under the concentration versus time curve in mg/mLmin. Based on the target carboplatin AUC, more than two thirds of patients were prescribed a carboplatin target AUC 5 mg/mL/min. In a sequential Phase II study, Carrato et al. between TBW and IBW. In the C-G equation to determine creatinine clearance, the adjusted body weight was used for BMI>or=27 patients and serum creatinine value of 70.7 microM (0.8 mg/dl) for the cachectic patients. AUC (Area Under the Curve) the area under the pharmacokinetic curve the concentration-time curve (change in the concentration of the active substance in plasma or serum over time). J Clin Oncol. The FDA has recommended that physicians consider capping the dose of carboplatin for desired exposure (AUC) to avoid potential toxicity due to overdosing. The maximum dose is based on a GFR estimate that is capped at 125 mL/min for patients with normal renal function. J Clin Oncol.

Here is how the Carboplatin AUC Dose for Female calculation can be explained with given input values -> 5.850E+8 = 5*(92+25). Recalculation of carboplatin doses at each cycle is unnecessary, except when baseline kidney function (e.g., eGFR) alters by > 20% or when there is a change in the clinical status of the patient. The most relevant pharmacokinetic parameter for drug exposure is the area under the curve (AUC) of plasma concentration x time following a single dose. The maximum dose is based on a GFR estimate that . Carboplatin AUC dose. Cisplatin + Etoposide 141,142,dd,mm-oo. The formula is: dose (mg) = AUC (mg ml-1 min) x [GFR (ml/min) + 25 (ml/min)]. Refer to regimen for target AUC. Target AUC is the carboplatin target area under the concentration. min gave rise to manageable hematological toxicity in previously treated and untreated patients, respectively, and hence target AUC values of 5 and 7 mg/mL min are recommended for single-agent carboplatin in these patient groups. infusion over 30 minutes on Day 1; Neoadjuvant Phase 1 is repeated every 3 weeks or 21 days.
