To evaluate the change in lipids and insulin sensitivity in 10 obese type II diabetic patients after treatment with benfluorex or placebo for 2 wk.
The study had a double-blind, cross-over design. Insulin sensitivity was measured with the euglycemic hyperinsulinemic glucose clamp technique at two different insulin infusion rates: 0.05 (clamp 1) and 0.10 U.kg−1 · h−1 (clamp 2).
Subanalysis of the glucose infusion rate under steady-state conditions in the last 30 min of clamp 2 yielded a glucose infusion rate of 5.36 and 3.87 mmol.kg−1.min−1 after benfluorex and placebo, respectively (P = 0.018).
Benfluorex increases insulin sensitivity in obese type II diabetic patients.
