  1. Overview of the area under the curve from 0 to 58 h (AUC0–58 h) for fecal concentrations, maximal and minimal fecal concentrations (Cmax and Cmin) and average steady state fecal concentrations (Cpssfecal) for groups 1, 2, 3 and 4. Linearity was checked by normalizing Cmax for dose (D) administered (Cmax/D). A difference in superscripts a, b or c denotes a statistical significant difference between these groups. Statistics were exerted using a single-factor ANOVA with a post-hoc Tukey test (equal variances checked), significance level 0.05. For Cmax/D an independent-samples T test was used to compare the mean values between group 1–2 and 3–4
