Patient Factors That Increase Infliximab Clearance and Shorten Half-life in Inflammatory Bowel Disease

Abstract

IFX-CL is significantly influenced by patient factors, specifically, albumin, body weight, and ATI. There should be a decreasing IFX dose interval strategy, particularly for low albumin patients. Higher starting doses may benefit low body weight patients. Pharmacokinetic models and therapeutic drug monitoring may ensure that patients maintain measurable concentrations throughout dose intervals. Individualized dosing may improve outcomes for IFX-treated patients with Crohn's disease and ulcerative colitis.
