CONTEXT: Systemic arterial hypertension is part of the metabolic syndrome resulting from obesity. OBJECTIVE: To evaluate the effect of sibutramine on overweight and obese patients’ blood pressure through a systematic review. METHODS: All the studies included needed to be randomized controlled trials. The methodological quality of the selected trials was assessed using the criteria described in the Cochrane Handbook. The participants were overweight and obese patients; the intervention was sibutramine compared with placebo. The primary outcome measurement was systolic and diastolic blood pressure and the secondary measurement was blood pressure. Studies were identified by searching the following sources: Literatura LatinoAmericana e do Caribe em Ciências da Saúde (Lilacs), Medline, Cochrane reviews, manual searches, personal communication and contact with the pharmaceutical industry. There were no language, date or other restrictions. Data collection and extraction was performed by two reviewers, who independently obtained the full articles of all eligible papers. RESULTS: Three meta-analyses were produced: 1) systolic blood pressure outcome (eight studies) did not show statistical signifi cance between sibutramine and placebo: weighted mean difference (WMD) 1.57, confi dence interval (CI) -0.03 to 3.18; 2) diastolic blood pressure outcome (ten studies) did not show statistical signifi cance between sibutramine and placebo: WMD 1.13, CI -0.49 to 2.76; 3) blood pressure outcome (two studies) also did not show statistical signifi cance between the groups: relative risk (RR) 0.69, CI 0.07 to 7.01. CONCLUSIONS: The meta-analyses presented in this systematic review show that sibutramine does not have a statistically signifi cant effect on blood pressure, compared with placebo.
