摘要: The renal clearance of melphalan and the fraction unbound in plasma were determined after intravenous infusion 5 mg/m2 over min nine patients with cancer to obtain information regarding mechanism handling melphalan. Four underwent bone marrow transplantation also received an IV dose 220 mg/m2. Total ranged from 66.0 272 ml/min per m2; percentage excreted unchanged urine, 2.5% 92.8%; clearance, 4.1 188 plasma, 0.0598 0.460; t1/2β, 39.4 84.3 min. Unbound calculated for each patient 441 3356 m2 15 961 respectively not related serum albumin, creatinine or clearance. exctreted urine flow. There was evidence active secretion kidney possible reabsorption. no significant paired differences disposition between high- low-dose studies. Highly variable involving may contribute part large interpatient total cancer.
