Insulin requirements in diabetic patients treated with sulphinpyrazone

Forty-one adult diabetic patients of either sex who had been controlled by insulin alone for at least one year were randomly allocated in a double-blind, between-patient study, to either sulphinpyrazone (600--800 mg daily) or an identnd at the end of it, no clinically or statistically significant change of the insulin needs of the patients was observed. It is concluded that no clinical interaction occurs between sulphinpyrazone (800 mg/day or 600 mg/day) and insulin when they are administered simultaneously for long periods. In the doses used the tolerability of sulphinpyrazone was very good.
