Place of azathioprine for Crohn's disease.

The clinical effects of azathioprine have been compared with those of corticosteroids in a group of 112 patients who have come under the care of a single unit between 1963 and 1975. There is no clear evidence that azathioprine alters the course of the disease in the long term; it is of value in obtaining a remission, particularly when the disease affects the large intestine.
