OBJECTIVE:Sibutramine and orlistat are currently used for weight loss. We aimed to investigate the effect of orlistat and sibutramine combination therapy in treatment of obese women. SUBJECTS AND DESIGN: Study population consisted of 89 obese women who had a body mass index > or = 30 kg/m2, were normotensive, and had normal glucose tolerance. All patients were placed on a diet which contained fat approximately 30% of total calorie intake and the diet was designed to cause an energy deficit of approximately 2.51-3.56 megajoule/day. At the first month of diet (baseline), all patients were randomly divided into three therapy groups: Diet + Orlistat (group 1; n = 30 patients), Diet + Sibutramine (group 2; n = 29 patients), Diet + Orlistat + Sibutramine (group 3; n = 30 patients). Body weight, body fat distribution and serum lipid levels were evaluated baseline and after six months in all subjects. RESULTS:Mean weight loss was 5.5 +/- 4.9 kg (p = 0.024) in group 1, 10.1 +/- 3.6 kg (p < 0.001) in group 2, 10.8 +/- 6.6 kg (p < 0.001) in group 3 after the six months. Weight loss was significantly greater in group 2 (p = 0.003) and group 3 (p = 0.002) when compared with group 1. Percentage of mean weight loss was 5.5 +/- 3.1% in group 1, 10.2 +/- 4.8% in group 2, 10.6 +/- 5.7% in group 3. Percentage of weight loss was higher in group 2 (p = 0.01) and group 3 (p = 0.009) when compared with group 1. Weight loss and percentage of weight loss were not different between group 2 and group 3. CONCLUSION: These three regimens had different results on weight loss in obese women. Combination drug therapy and sibutramine therapy were both more effective than orlistat therapy alone. However, no significant difference was noted between combination drug therapy and sibutramine treatment groups.
