Current pharmacologic therapies and emerging alternatives in the treatment of ulcerative colitis.

Recent progress in both basic and clinical research has led us to develop sophisticated and effective medical therapy of ulcerative colitis (UC). Although classical agents such as aminosalicylates, corticosteroids and immunomodulatory drugs have remained as the gold standard for decades, their novel formulations and/or dosage regimens have changed their placements in the medical management of UC. In addition, studies have shown that a number of novel therapeutic agents, designed to target specific mechanisms involved in the inflammatory cascade, have efficacy for the treatment of UC and they will have significant clinical impacts in the near future. A clear understanding of the proven and potential benefits of both the standard and emerging therapies will be required for the optimum individual care of patients with varied clinical presentations.
