Sumario:Central obesity have an important impact on the development of risk factors for coronary heart disease, including dislipidemia, glucose intolerance, insulin resistance and hypertension. These factors contribute to building cardiovascular (CV) disease as a major cause of death. The approach to obesity therapy should be designed to reduce CV risk and mortality. Diet and lifestyle changes remain the cornerstones of therapy for obesity, but the resultant weight loss is often small and long-term success is uncommon and disappointing. Drug therapy is considered for individuals with a body mass index greater than 30 kg/m² or ranging from 25 to 30 kg/m² if they have comorbid conditions. Antiobesity agents can be helpful to some patients in achieving and maintaining meaningful weight loss, but yet our pharmaceutical tools are of limited effectiveness considering the magnitude of the problem. At the present, only two drugs, orlistat and sibutramine, are approved for long-term treatment of obesity and promote no more than 5 to 10% of weight loss. Rimonabant, a cannabinoid-1 receptor antagonist, was withdrawn from the market because of concerns about its safety, including risk of suicidal and seizures, although very effective in promoting clinically meaningful weight loss, reduction in waist circumference, and improvements in several metabolic risk factors, rimonabant, a cannabinoid-1 receptor antagonist was withdrawn from the market because it concerns about its safety, including risk of suicidal and seizures. Fortunately, recent fundamental insights into the neuroendocrine mechanisms regulating body weight provide an expanding list of molecular targets for novel, rationally designed antiobesity drugs. In this review, the therapeutic potential of some antiobesity molecules in the development will be analyzed based on an understanding of energy homeostasis.
