Novel drug therapies in inflammatory bowel disease.

Steroids that are topically active or rapidly metabolized have a definite therapeutic role and have fewer long-term side-effects than other steroids. Methotrexate can promote remission in approximately 50% of patients, but is less effective in maintaining remission.
