Apparent Volume of Distribution (Vz/F) for Total Alectinib

Total alectinib = unbound alectinib plus alectinib bound to plasma proteins. Volume of distribution is defined as the theoretical volume which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose is influenced by the fraction absorbed.

Time frame: Predose (0 hour), and at 1, 2, 4, 6, 8, 10, 12, 18, 24, 36, 48, 72, 96, 120, 144, 168, 192, 216, and 240 hours postdose (Dosing day = Day 1)
