Effect of low-dose metoprolol in combination with sibutramine therapy in normotensive obese patients: a randomized controlled study

OBJECTIVE: Sibutramine is an effective appetite suppresser agent, but treatment is often complicated with side effects, including palpitations and hypertension. In this study, we aimed to assess the effect of low-dose cardio-selective beta blocker combination with sibutramine treatment. METHODS: In...

description OBJECTIVE: Sibutramine is an effective appetite suppresser agent, but treatment is often complicated with side effects, including palpitations and hypertension. In this study, we aimed to assess the effect of low-dose cardio-selective beta blocker combination with sibutramine treatment. METHODS: In total, 57 obese subjects were enrolled in the study and separated into two groups in order to receive sibutramine 10 mg/day plus placebo (group P) or sibutramine 10 mg/day plus metoprolol 25 mg/day (group M). Patients were evaluated in the beginning and at the end of the third month with anthropometric measurements, biochemical analysis, peripheral insulin resistance, and ambulatory 24 h blood pressure monitoring. Side effects were evaluated with a visual analog scale. RESULTS: During the study period, the drop-out rate was significantly higher in group P compared with group M (55 and 21%, respectively, P =0.014). Palpitations and headache were prominent symptoms in group P. Diastolic blood pressure (78.6±11.6 and 70.6±4.8 mmHg, respectively, P =0.013) and mean heart rate (84.3±6.1 and 75.8±8.4 beats/min, respectively, P =0.003) were significantly higher in group P compared with group M at the end of the third month. Weight loss was similar between the two groups (100.9±11.5 to 91.8±12.8 kg for group P, P
