At present only two drugs are approved for long-term treatment of obesity.
Sibutramine
inhibits the reuptake of serotonin and norepinephrine. In clinical trials it produces a dose-dependent 5-10% decrease in body weight. Its side effects include dry mouth, insomnia, asthenia, and constipation. In addition, sibutramine produces a small increase in blood pressure and pulse that is a contraindication to the use of this drug in some individuals with
heart disease
. Xenical is the other drug approved for long-term use in the treatment of obesity. It works by blocking lipase and thus increasing the fecal loss of triglyceride. One valuable consequence of this mechanism of action is the reduction of serum cholesterol that averages about 5% more than can be accounted for by weight loss alone. In clinical trials it produces a 5-10% loss of weight. Its side effects are entirely due to undigested fat in the intestine that can lead to increased frequency and change in the character of stools. It can also lower fat-soluble vitamins. The ingestion of a vitamin supplement before bedtime is a reasonable treatment strategy. The effect on weight loss during long-term trials with these two drugs is shown in Figs 7 and 8 above. Also in this figure is data on phentermine used in trials of six months or more. Although there were differences in mean weight losses with these drugs, when the placebo effect was taken into account they all had a surprisingly similar magnitude of weight loss.

Obesity is associated with increased risk of conditions such as hypertension, dyslipidaemia, diabetes mellitus, and obstructive sleep apnoea. Pharmacotherapy for obesity should be considered in combination with lifestyle changes in obese patients, or overweight patients with other conditions that put them at risk of developing
heart disease
.
Sibutramine
and orlistat are the only two anti-obesity medications approved for long-term use.
Sibutramine
is a serotonergic and adrenergic drug that reduces food intake. Orlistat is a gastrointestinal lipase inhibitor that interferes with fat absorption. However, it commonly causes flatulence and diarrhoea. Rimonabant is the first of a series of endocannabinoid receptor antagonists. It was approved by the Committee for Medicinal Products for Human Use of the European Medicines Agency (EMEA) as an adjunct to diet and exercise in treating obesity in 2006. However, despite the extensive clinical trial data, EMEA announced in 2008 that it has recommended suspension of rimonabant because of its psychiatric side effects. Studies evaluating the long-term safety and efficacy of anti-obesity agents are needed.

Roughly two thirds of U.S. adults are overweight or obese. Obesity increases the risk of hypertension, type 2 diabetes mellitus, hyperlipidemia,
heart disease
, pulmonary disease, hepatobiliary disease, cancer, and a number of psychosocial complications. Physicians often feel unprepared to handle this important problem. Practical office-based strategies include: (1) making recommendations for assisted self-management, including guidance on popular diets, (2) advising patients about commercial weight-loss programs, (3) advising patients about and prescribing medications, (4) recommending bariatric surgery, and (5) supplementing these strategies with counseling about lifestyle changes using a systematic approach. Family physicians should provide basic information about the effectiveness and safety of popular diets and commercial weight-loss programs, and refer patients to appropriate information sources.
Sibutramine
and orlistat, the only medications currently approved for the long-term treatment of obesity, should only be prescribed in combination with lifestyle changes. Bariatric surgery is an option for adults with a body mass index of 40 kg per m2 or higher, or for those with a body mass index of 35 kg per m2 or higher who have obesity-related comorbidities such as type 2 diabetes. The five A's behavioral counseling paradigm (ask, advise, assess, assist, and arrange) can be used as the basis for a systematic, practical approach to the management of obesity that incorporates evidence for managing common obesity-related behaviors.
