(a) Calculated SAX DPP-4 inhibition ratios versus predicted values. The linear line is red and the OV vs. PRE points are black solid square. (b) PD profiles of parent SAX in T2DM rats following a intragastric dose of 10 mg/kg. The blue solid points represent calculated individual DPP-4 inhibition ratios (n=3). The red solid line represents model fitting curve. (c) The dose-effect curve of parent SAX in T2DM rats. The arrow indicates that the efficacy of the drug shows a downward trend with the time of administration
