This medication review explores the role of stable pharmacokinetics (PK) in achieving continuous inflammatory control in inflammatory bowel disease (IBD), with a focus on subcutaneous infliximab therapy for Crohn’s disease and ulcerative colitis. Kim Orleck, PA-C, from Atlanta Gastroenterology Associates and United Digestive, reviews how subcutaneous infliximab provides more stable and sustained drug exposure compared with traditional intravenous (IV) infliximab dosing. By minimizing peak-to-trough fluctuations and maintaining higher trough concentrations, subcutaneous infliximab may help support continuous TNF inhibition, reduce immunogenicity risk, and improve long-term disease control in patients with moderate to severe IBD.
The discussion highlights key clinical data from studies including REMSWITCH, LIBERTY Crohn’s, and LIBERTY UC, demonstrating that subcutaneous infliximab delivers durable remission, stable safety outcomes, and consistent therapeutic drug levels through long-term follow-up. Learn how transitioning from IV to subcutaneous infliximab may improve patient convenience, maintain clinical and endoscopic remission, and support treat-to-target goals in IBD management. The review also examines which patients may require closer monitoring or dose escalation strategies following the switch from IV biologic therapy.
