Abstract

Benfluorex is a hypolipidaemic agent with biguanide-like properties. To evaluate its blood glucose lowering action, a single-blind study protocol was designed. Two groups of seven type II (non-insulin-dependent) diabetic patients matched for age (50 +/- 4 vs. 53 +/- 1 years), sex, body mass index (27.8 +/- 0.6 vs. 26.5 +/- 0.7 kg/m2), and duration of diabetes were studied before and after 1 month of treatment with benfluorex 150 mg tid (= tres in die = three times a day), PO (= per os = by mouth) or a placebo, respectively. All patients had previously been treated by diet alone. In all patients, parameters of glucose and lipid metabolism were obtained. Insulin sensitivity was assessed by means of a euglycaemic (5.1 +/- 0.1 mM) hyperinsulinaemic (516 +/- 28 pM) clamp performed in combination with [3(-3)H]glucose infusion and indirect calorimetry. In no case was there a significant change in body mass index (27.6 +/- 0.5 vs. 26.4 +/- 0.7 kg/m2). After 1 month of treatment, fasting plasma glucose (6.8 +/- 0.2 vs. 8.1 +/- 0.6 mM) and HbA1C (glycated haemoglobin; 6.5 +/- 0.2 vs. 8.0 +/- 0.7%) were lower in the benfluorex group than in the placebo-treated patients (both p < 0.05). No change was observed in hepatic glucose production (HGP) (13.5 +/- 1.4 vs. 13.9 +/- 1.1 mumol/min per kg), the basal rate of glucose, and lipid oxidation and non-oxidative glucose metabolism, or in plasma triglyceride and total cholesterol concentrations.
