infliximab is used in inflammatory bowel disease, which has a great inter-individual pharmacokinetic variability. Thus, it is necessary to individualize the therapy in many cases. The main objective of our study was to compare two methods of a dose adjustment strategy using therapeutic drug monitoring: a) based on an algorithm and b) based on Bayesian prediction, to achieve an optimal infliximab trough level in patients with inflammatory bowel diseases. The secondary objective was to evaluate the predictive performance of a population pharmacokinetic model of infliximab in patients with inflammatory bowel diseases and therefore, its clinical utility. Furthermore, the factors associated with a suboptimal adjustment of the model were analyzed.
