Drug treatment of obesity

This review is dealing with currently available medications used in the treatment of obesity. Unfortunately currently available drugs did not prove effective in the long term treatment of obese patients. Fenfluramin and D-Fenfluramin has been withdrawn from the market because of severe side effects as pulmonary hypertension and valvular heart disease. Sibutramin, a serotonin noradrenalin reuptake inhibitor, will be available this year. Orlistat, an inhibitor of pancreatic lipases. has proven effective for weight reduction in obese patients. New drugs as alpha 2-adrenergic antagonists, cholecystokinin, neuropeptide y, bombesin and leptin are in the pipeline.
