Pharmacologic agents for weight reduction.

Obesity is a major health problem in U.S. adults. Most successful weight loss programs have multiple components, including lifestyle modifications, reduced caloric intake, and exercise. Short-term use of medications for weight loss may be a part of such a plan. Currently, most medications are adrenergic stimulants and can produce adverse CNS and cardiovascular effects. Antiabsorptive agents appear to be safer but have significant GI side effects. An important finding is the potential for adverse life-threatening effects with over-the-counter products and dietary supplements that do not undergo evaluation similar to prescription drugs. The search continues for safe and effective pharmacologic agents to assist in weight loss.
