What are the current treatments for Crohn's disease?3 answersTreatment options for Crohn's disease have been rapidly developing and expanding over the past decade. Multiple classes of medications are currently available, including 5-aminosalicylates (5-ASA), antibiotics, glucocorticoids, thiopurine immunosuppressives, methotrexate, tumor necrosis factor (TNF) alpha antagonists, and anti-integrin therapies. The goals of treatment have expanded beyond symptom relief to include long-term remission, avoidance of corticosteroids, prevention of complications, and improvement of quality of life. However, the benefits of these medications must be balanced with potential drawbacks such as increased risks of infections, malignancies, and financial burden. The main objectives of clinical therapy in Crohn's disease are achieving clinical and endoscopic remission without long-term corticosteroid use, preventing hospitalization and surgery, and improving quality of life. Recent advances in treatment include the use of treatment algorithms, therapeutic drug monitoring, optimal management of post-surgical patients, and the role of multi-disciplinary clinics.
