Sibutramine offers three types of benefit in weight management: by enhancing weight loss, by improving weight maintenance and by reducing the comorbidities of obesity. The clinical effects of sibutramine are explained through its known mode of action as a serotonin (5-HT) and noradrenaline reuptake inhibitor (SNRI). This dual mechanism of action results in two synergistic physiological effects--a reduction in energy intake and an increase in energy expenditure, which combine to promote and maintain weight loss.
