What does AUC mean for carboplatin?
What does AUC mean for carboplatin?
AUC is the “area under the curve” – a figure that reflects the concentration of drug in the body that doctors want to achieve; GFR is the glomerular filtration rate – the rate at which an individual patient’s kidneys work; A is the ratio of this glomerular filtration rate to how quickly the kidneys get rid of …
Why is AUC dosing used for carboplatin?
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.
What is the target AUC for a patient with a GFR 60 mL/min who is ordered carboplatin 425 mg?
-The target AUC of 4 to 6 mg/mL/min using single agent carboplatin appears to provide the most appropriate dose range in previously treated patients.
What is AUC dosing?
The most relevant pharmacokinetic parameter for drug exposure is the area under the curve (AUC) of plasma concentration x time following a single dose. During drug development, drug level sampling at multiple time points helps define the relationship between drug administration and the AUC.
How is carboplatin calculated?
The formula is: dose (mg) = AUC (mg ml-1 min) x [GFR (ml/min) + 25 (ml/min)]. This formula has proven to be, in both retrospective and prospective studies, a reliable tool to calculate the optimal dose of carboplatin Future studies should determine the value of the creatinine clearance as a measure for the GFR.
What are the common side effects of carboplatin?
Stomach pain, body aches/pain, diarrhea, constipation, weakness, nausea, and vomiting may occur. Nausea and vomiting can be severe in some patients but usually go away within 24 hours of treatment. Drug therapy may be needed to prevent or relieve nausea and vomiting.
Why carboplatin is given after paclitaxel?
The combination of carboplatin and paclitaxel is widely used to treat multiple solid tumors including ovarian, lung and breast cancer. Usually these drugs are given simultaneously with little regard to the importance of scheduling to obtain a maximal response.
What is a good value for AUC?
AREA UNDER THE ROC CURVE In general, an AUC of 0.5 suggests no discrimination (i.e., ability to diagnose patients with and without the disease or condition based on the test), 0.7 to 0.8 is considered acceptable, 0.8 to 0.9 is considered excellent, and more than 0.9 is considered outstanding.
How is AUC calculated?
The AUC can be computed by adjusting the values in the matrix so that cells where the positive case outranks the negative case receive a 1 , cells where the negative case has higher rank receive a 0 , and cells with ties get 0.5 (since applying the sign function to the difference in scores gives values of 1, -1, and 0 …
How does carboplatin make you feel?
You may get pain or discomfort in your tummy (abdomen). You may also feel bloated or have indigestion or wind. Your doctor can prescribe drugs to help improve these symptoms. Tell them if the pain does not improve or gets worse.
What are the long term effects of carboplatin?
Sensory loss, numbness and tingling, and difficulty in walking may last for at least as long as therapy is continued. These side effects may become progressively more severe with continued treatment, and your doctor may decide to decrease your dose.
How quickly does carboplatin work?
Each dose, or cycle, of carboplatin takes 15 minutes to an hour. It may take longer if you are having carboplatin with other drugs. You’ll usually have one cycle of carboplatin every 21–28 days.
How is the AUC of carboplatin calculated?
Combination chemotherapy with Carboplatin (CBDCA) and 5-fluorouracil (5-FU) was given to 115 patients with head and neck cancer. The area under the blood concentration-time curve (AUC) of CBDCA was calculated by Calvert’s formula for 111 of the 115 patients.
How is the AUC of CBDCA calculated?
The area under the blood concentration-time curve (AUC) of CBDCA was calculated by Calvert’s formula for 111 of the 115 patients. A retrospective study was conducted to define the relationship between the clinical outcome of the combination chemotherapy and the AUC of CBDCA.
Can you take carboplatin for head and neck cancer?
1 Department of Otorhinolaryngology, University of Occupational and Environmental Health, School of Medicine, Kjtakyushu. Combination chemotherapy with Carboplatin (CBDCA) and 5-fluorouracil (5-FU) was given to 115 patients with head and neck cancer.
