The significant correlation between the maximum and average concentration (Cmax, Cavg), as well as the area under the concentration–time curve (AUCtf) for posaconazole with the route of administration (oral vs. intravenous), the albumin concentration in plasma (presence or absence of hypoalbuminemia), and co-administration with ondansetron and levetiracetam, was demonstrated as presented in the Table 3. Here, ALB is linked to Hypoalbuminemia.
