This carboplatin dosing calculator uses the Calvert method to calculate the total carboplatin dose needed to achieve a given AUC (area under the free carboplatin plasma concentration versus time curve) while taking into account renal function. The area under the curve (AUC) of carboplatin was back-calculated from actual dosages using the Calvert formula. Carboplatin dosage Carbo dose = target AUC (mg/ml/min) x (CrCl + 25) (ml/min) Please read the disclaimer before using this calculator. CALVERT FORMULA FOR CARBOPLATIN DOSING: Total Dose (mg) = (target AUC) x (GFR + 25) Calvert AH, Newell DR, Gumbrell LA, et al. Ann Pharmacother. GFR for female (mL/min) describes the flow rate of filtered fluid through the kidney. Cisplatin + Etoposide 141,142,dd,mm-oo. . Calvert formula remains accurate when carboplatin is combined with etoposide, bleomycin, cisplatin, cyclophosphamide and ifosfamide; (5) some patients may experience more toxicity than others at equivalent AUC values; this may be due to the recovery capacity of the bone marrow in individual patients. This carboplatin dosing calculator uses the Calvert method to calculate the total carboplatin dose needed to achieve a given AUC (area under the free carboplatin plasma concentration versus time curve) while taking into account renal function. Accessed April 15, 2011. This online calculator allows you to find the AUC of carboplatin for a patient using the Calvert formula. Keeping the AUC within a defined range helps limit the dangerous side effects of chemotherapy. The chemoradiation arm consisted of cisplatin 50 mg/m 2 IV days 1 and 29 with external beam radiation therapy, followed by carboplatin (AUC 5-6) plus paclitaxel 175 mg/m 2 IV every 21 days for four cycles. Alternatively, carboplatin may be dosed once weekly at an AUC of 1.5 IV for 12 weeks. 5 Which is more accurate, carboplatin GFR or AUC? Carboplatin dosing should not be based on estimated GFR. Regardless of the number of cycles, the optimal dosing of carboplatin is calculated by the formula ( Calvert and Egorin, 2002 ). 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). If you continue to use this site we will assume that you are happy with it. The primary end . between TBW and IBW.

Additional factors that should be assessed include: previous exposure to chemotherapy or radiotherapy, and overall health status. 5) AUC-based carboplatin dosing is more accurate than dosing according to BSA. A clear relationship between carboplatin exposure, as quantified by area under the plasma concentration-time curve (AUC), and toxicity (thrombocytopenia) and response has been observed in ovarian cancer and other tumour types 9-11. The formula is: dose (mg) = AUC (mg ml-1 min) x [GFR (ml/min) + 25 (ml/min)]. How often should carboplatin be administered?

(used for ideal body weight calculation):130 - 220 cm- Serum AUC is a quick measure of how much of the drug an individual has been exposed to in a given amount of time. Our carboplatin calculator computes the carboplatin dose in two steps: Calculating GFR using the Cockcroft-Gault equation: MEN: GFR = ( (140 - A) W / (72 Cr) WOMEN: GFR = 0.85 GFR formula for men where: `GRF`- Glomerular Filtration Rate `A` - age (years) `W` - weight (kg) `Cr` - serum creatinine (mg/dL) This formula has also been used in patients with end-stage renal disease on hemodialysis by assuming that the GFR is zero. A study by In routine oncologic practice, the carboplatin dosage is usually estimated based on AUC-based dosing since carboplatin clearance closely matches creatinine clearance. Following a dose of carboplatin, approximately 60-80% is excreted in the urine within the first 24 h 8, 9. The model was reported to underpredict AUC by about 20% (1). Team Softusvista has created this Calculator and 600+ more calculators! How is the carboplatin AUC and dosage calculated? 2 These methods are costly and require time and expertise. Moderate (Carboplatin AUC < 5) Extravasation Potential: None The following table contains adverse effects reported with single agent carboplatin in the product monograph. The Calvert formula has been extensively used to determine the dose of carboplatin for a fixed AUC and glomerular filtration rate (GFR). Body Surface Area Calculator. The first step is to enter the total mg of platinum in your prescription. A carboplatin calculator is an instrument that measures the amount of carbon and platinum used in a catalytic converter. 80 mg/m2 IV once weekly for 12 weeks in combination with carboplatin (AUC 5 IV on day 1 every 3 weeks for 4 cycles) and pembrolizumab (200 mg IV every 3 weeks OR 400 mg IV every 6 weeks); administer pembrolizumab prior to chemotherapy when given on the same day.

This carboplatin dosing calculator uses the Calvert method to calculate the total carboplatin dose needed to achieve a given AUC (area under the free carboplatin plasma concentration versus time curve) while taking into account renal function. the Curve) of carboplatin. All Oncologists declared to use Calvert formula to calculate AUC 7 dose, and administered a median of 900 mg of carboplatin (range 690 to 1535). Target AUC is the carboplatin target area under the concentration. The glomerular filtration rate (GFR), the fluid volume filtered from the capillaries of the renal glomeruli into the Bowman's capsule per unit time, is used for calculations of carboplatin chemotherapy doses. Refer to regimen for target AUC. GFR for Male = (((140-age) / serum creatinine) * 1) (weight (kg) / 72), GFR for Female = (((140-age) / serum creatinine) * 0.85) (weight (kg) / 72), Carboplatin Dose = Target AUC * (GFR + 25). .

Carboplatin is a frequently used antitumour agent recommended to be administered according to the Calvert formula: dose = AUC x (GFR+25), where GFR is the glomerular filtration rate as measured by . Occasionally carboplatin is injected directly into a body cavity rather than the bloodstream. The maximum dose is based on a GFR estimate that is capped at 125 mL/min for patients with normal renal function. This formula can be used to calculate the carboplatin dose accurately in order to obtain a target AUC by using only the GFR. Carboplatin is typically given once every 3-4 weeks (every 21-28 days), but may occasionally be given weekly (every 7 days).
