OBJECTIVE--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. RESEARCH DESIGN AND METHODS--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). RESULTS--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).
CONCLUSIONS--Benfluorex increases insulin sensitivity in obese type II
diabetic patients.
