Abstract
Inflammatory bowel disease (IBD), encompassing Crohn's disease (CD) and ulcerative colitis (UC), is a chronic and often debilitating condition requiring complex and individualized management. Over the past few decades, advancements in understanding IBD pathophysiology have led to a transformative shift in therapeutic approaches. This article provides a comprehensive overview of the evolution of IBD treatments, from early symptom-focused therapies to modern biologics, small molecule agents, and emerging treatment strategies. We discuss therapeutic goals centered on achieving clinical remission, endoscopic/mucosal healing, and enhancing patient quality of life. Additionally, we explore the rationale for the early and personalized use of biologic therapies in moderate-to-severe cases, review the current FDA-approved agents as of 2024, and highlight the advantages and limitations of these treatments. Special attention is given to the evolving role of novel oral therapies, including Janus kinase inhibitors and sphingosine-1-phosphate receptor modulators, and future new directions. This paper aims to guide clinicians in navigating the expanding therapeutic landscape of IBD, emphasizing patient-centered decision-making and addressing ongoing challenges in achieving optimal disease control.
