Key facts

  • Busulfan area under the curve panel - Plasma
  • Busulfan area under the curve panel
  • The results of this panel will help guide dosing adjustments to achieve complete bone marrow ablation while minimizing dose-dependent toxicity of busulfan. Busulfan is generally given in 2H infusions, once every 6H for 4 days (a total of 16 doses). Ideally, this pharmacokinetic evaluation of the area under the curve (AUC) and clearance after the first dose is performed to help guide dosing with results available by the 5th dose.
