1. Change in Equation (1)

We have found two typographical errors in Equation (1) and we wish to replace

$$P_{\mathrm{eff}}=\frac{-{Ø}_{\mathrm{in}}}{2\pi RL}\times Ln \frac{C_{\mathrm{in}}}{C_{\mathrm{out}.\mathrm{cor}}}$$

With

$$P_{\mathrm{eff}}=\frac{-{Ø}_{\mathrm{in}}}{2\pi RL}\times Ln \frac{C_{\mathrm{out}.\mathrm{cor}}}{C_{\mathrm{in}}}$$

2. Change in Table 2

We have found a typographical error in the P_eff heading in Table 2. In addition, and after reviewing the calculations again, we have detected that the data shown in Table 2 for levofloxacin did not consider the normalization of the 10-cm intestinal segment. With the normalization, the P_eff value for levofloxacin increases (according to the length of the intestinal segment used). For these reasons, the authors wish to replace
