After a bit more number crunching, they came up with what is now known as the Calvert formula - a calculation that's still used to this day to calculate the correct dose of carboplatin. The area under the curve (AUC) of carboplatin was back-calculated from actual dosages using the Calvert formula. 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). 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. Following a dose of carboplatin, approximately 60-80% is excreted in the urine within the first 24 h 8, 9. Glomerular Filtration Rated was estimated mainly by Cockroft-Gault formula (55% of pts), Jeliffe formula (27%), 24-hour urine collection (17%), MDRM (1%): median value was 106 ml/min (range 75 to 209).

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. AUC is a quick measure of how much of the drug an individual has been exposed to in a given amount of time. Carboplatin is a second-generation platinum compound with a broad spectrum of antineoplastic properties. 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. How is the Calvert formula used to calculate AUC? Male = 50 kg + (2.3 x (Height in inches - 60)) Female = 45.5 kg + (2.3 x (Height in inches - 60)) The ideal weight result is converted in both kg and lbs for convenience, where (1 kg = 2.20462262 lbs).
