General principles and pharmacology of biologics in inflammatory bowel disease

The pharmacology of each biologic agent is important regarding the dose required to achieve benefits, duration of therapeutic effect, and the induction of immunogenicity. Comprehension of the individual pharmacology, pharmacodynamics, and pharmacokinetics, in addition to the impact of concomitant immunomodulation on immunogenicity allows optimization of each biologic agent in the appropriate inductive or maintenance setting of IBD.
