Orlistat in hypertensive overweight/obese patients: results of a randomized clinical trial.

Abstract：

OBJECTIVE:To assess the effect of orlistat plus diet compared with diet alone in promoting weight loss and blood pressure reduction in hypertensive, overweight/obese patients. DESIGN:A pragmatic randomized, controlled trial. SETTING:Hypertension clinic of a university hospital. PATIENTS:Hypertensive patients aged 18-75 years with a body mass index greater than 25 kg/m(2). INTERVENTIONS:Orlistat 360 mg/day combined with a hypocaloric diet (treatment group), or a calorie-restricted diet alone (control group). MAIN OUTCOME MEASURES:Primary outcomes were reductions in weight and blood pressure. Secondary outcomes were decreases in lipid and glucose concentrations. A subgroup analysis of the main outcomes among diabetic and non-diabetic patients was also performed. RESULTS:A total of 204 patients were included in the intention-to-treat analysis. After 12 weeks the orlistat group lost, on average, 3.7 kg and the control group lost 2.0 kg in weight (P < 0.001). Systolic (SBP) and diastolic (DBP) blood pressures decreased by 15.3 and 11.4 mmHg, respectively, in the group given orlistat plus a hypocaloric diet and by 11.6 and 5.2 mmHg, respectively, in the control group given the calorie-restricted diet alone (P = 0.25 and P = 0.0004, respectively). Fasting glucose (0.82 and 0.17 mmol/l, P = 0.01) and total cholesterol (0.85 and 0.56 mmol/l, P = 0.05) were reduced to a greater extent with orlistat than with diet alone. The mean reduction in triglycerides with orlistat plus the hypocaloric diet was 0.75 mmol/l and that in the control group was 0.30 mmol/l (P = 0.28); the increases in high-density lipoprotein cholesterol were 0.05 and 0.00 mmol/l, respectively, in the two groups (P = 0.17). Treatment improved blood pressure and glucose control in the individuals with diabetes, but not in those without diabetes. CONCLUSION:In both groups there was a reduction in weight, blood pressure and metabolic parameters. The orlistat group performed better in reducing weight, DBP, glucose and cholesterol. Results show that even a small reduction in weight helps to control blood pressure and glucose. The cost-benefit of the use of orlistat should be evaluated for hypertensive obese patients.
