PURPOSE: To evaluate the efficacy and tolerability of different therapies associated with diet in the treatment of hypertensive obese patients. METHODS: In a clinical study we randomly evaluated 39 hypertensive obese patients (body mass index (BMI) > or = 30 kg/m2). After 45 days of diet the patients were again randomly distributed in 3 groups and received in double blind way: group 1-hypocaloric diet+placebo; group 2-hypocaloric diet+dexfenfluramine; group 3-hypocaloric diet+spiruline+fucus+gelatin. We followed their progress during 12 weeks under medication and further 24 weeks without. We evaluated the groups comparing: weight, BMI, blood pressure and side-effects. RESULTS: Twenty seven patients completed the observation. In those patients from groups 1 and 3 no changes in any of parameters were observed. In group 2 we observed a clear loss of weight (-3.8 Kg) and a fall in BMI. Blood Pressure changes were only observed in group 2 (-9.6%). The only patients to maintain weight loss after the termination of use of medicines were those from group 2. We did not observe any side-effects. CONCLUSION: In hypertensive obese patients, when isolated diet is not enough to control weight loss, dexfenfluramine could be useful in association with a controlled diet. The drug assists in weight loss, does not promote side-effects and does not interfere in the treatment of blood pressure.
