WebCreatinine clearance ( CrCl) is an estimate of Glomerular Filtration Rate ( GFR ); however, CrCl is slightly higher than true GFR because creatinine is secreted by the proximal tubule (in addition to being filtered by the glomerulus). The additional proximal tubule secretion falsely elevates the CrCl estimate of GFR. 12 WebThe parent compound, cisplatin, is excreted in the urine and accounts for 13% to 17% of the dose excreted within one hour after administration of 50 mg/m. 2. The mean renal clearance of cisplatin exceeds creatinine clearance and is 62 and 50 mL/min/m 2 following administration of 100 mg/m 2 as 2-hour or 6- to 7-hour infusions, respectively.

WebDec 16, 2024 · The heterogeneity of the subgroup of creatinine clearance in Leu 2024 was due to the fact that patients received an unusual dose of cisplatin (cisplatin, 40 mg/m 2) and mannitol (12.5 g). While 89 patients received 25 g of mannitol and 6 received 12.5 g in Williams 2016, the different doses of mannitol may be the reason for the heterogeneity of ... WebFeb 9, 2024 · Creatinine clearance is a measure of how well the kidneys filter creatinine out of the bloodstream for excretion in urine. Creatinine clearance is usually determined from a measurement of creatinine in a 24-hour urine sample and from a serum sample taken during the same time period. However, shorter time periods for urine samples may … lith med term def

WebMeasurements of Blood Urea Nitrogen (BUN), serum creatinine and creatinine clearance should be taken before initiating cisplatin therapy, and prior to subsequent doses, as toxicity is cumulative. Cisplatin is recommended to be given once every 3-4 weeks. Hydration is recommended to minimise nephrotoxicity. WebMay 8, 2024 · Cisplatin chemotherapy is used alone or in combination to treat a variety of cancers, including ovarian, testicular, lung, cervical, bladder, head and neck, and gastric cancers as well as lymphoma, melanoma, and more. Although it offers options for many cancer types, its use may result in nephrotoxicity, a dose-limiting side effect. WebEstimating GFR with the aMDRD formula and adding an intermediary level of dose reduction for patients with eGFR from 50 to 59.9 mL/min may result in a higher cumulative dose of … lith medical meaning
