Cmax in pharmacokinetics

WebToxicokinetic data have traditionally been presented as maximum observed plasma concentrations (C(max)) and area under the concentration time curve (AUC) values. These values have been used to compare exposures across studies and species to provide valuable interpretation of drug safety data. Increa … WebThe ANOVA performed on dose-normalized Cmax showed no statistically significant dose effect, demonstrating a dose-proportional increase of Cmax in this range of clopidogrel doses. The urinary excretion of SR26334 was low-2.2 to 2.4% of the dose administered-and Cl(r-2-24) remained virtually constant at all four doses.
