Orlistat (Xenical, Hoffmann-La Roche) is a powerful inhibitor of gastrointestinal lipase and as such, reduces fat absorption. Unlike other weight-reducing drugs it is minimally absorbed and has no effects in the CNS. Orlistat is indicated for patients with a body mass index (BMI) of at least 30 kg/m2 or 28 kg/m2 in the presence of obesity-associated complications, such as hypertension, diabetes mellitus, hyperlipidaemia and obstructive sleep apnoea. In clinical trials, orlistat (120 mg t.i.d.) in combination with life-style modification and a hypocaloric diet (30% of energy from fat) induced significantly more weight loss and improved health complications of obesity (diabetes, hypertension, hyperlipidaemia) compared to patients treated with diet alone. Side effects related to fat malabsorption, occurred in more than 20% of subjects during the first year of treatment and included oily faecal spotting, abdominal pain, flatus with discharge and fatty/oily stool. Side effects from orlistat diminished in the second year of treatment. Plasma concentrations of fat soluble vitamins decreased in orlistat-treated patients but did not usually fall below the normal range. No studies have evaluated the efficacy of orlistat or side effect profile beyond two years.

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.
