A  major fraction of dose is inactivated by cytidine deaminase in the liver and other body tissues. After 24 hrs, 80% of dose has been eliminated either as the inactive metabolite or as unchanged cytarabine, mostly in the urine, but some in the bileElevated baseline serum creatinine  (&gt;1.2 mg\/dl) is an independent risk factor for the development of neurotoxicity during treatment with high-dose cytarabine. Retrospective analysis implicates impaired  renal function as an independent risk factor for high-dose cytarabine-induced cerebral and cerebellar toxicity. The incidence of neurotoxicity was  86\u2013100% following administration of high-dose cytarabine to patients with CrCl &lt;40 mL\/min and 60\u201376% following administration to patients with CrCl 60 mL\/min received high-dose cytarabine, the incidence of neurotoxicity was found to be 8%, which correlates with the overall incidence of this adverse effect.
