Treatment of ulcerative colitis.
Advances in the treatment of ulcerative colitis have continued to focus on improved local delivery of existing agents, such as 5-aminosalicylate and corticosteroids, and on novel immunosuppressive agents. Although newer preparations of 5-aminosalicylate continue to provide incremental benefits in safety, tolerance, and efficacy, there is a growing understanding of the limits of benefit from increasing doses. Knowledge of the safety of these agents, particularly in regard to their use in pregnancy, continues to expand. Novel corticosteroids are used in much of the world for the treatment of ulcerative colitis, with the exception of the United States, with anticipated benefits in safety but little additional therapeutic benefit. Innovative use of oral emulsion preparations of cyclosporine has been reported in the treatment of ulcerative colitis and adds to the growing body of literature on the efficacy of cyclosporine in severe disease. Relatively limited experience with other immunosuppressive agents, such as tacrolimus, has been reported. The role of antibiotics in the treatment of ulcerative colitis has continued to present controversy.
