      Unbound Cmax and unbound Cmin represent the free plasma concentration after protein-binding correction. Protein bindings of lopinavir and ritonavir are 98%–99%. 98.5% were used here to calculate the unbound values.
      In vitro anti-HIV activity values used here obtained from the in vitro activity study absence of human albumin.
