Orlistat is an obesity drug sold under the trade names Xenical (Roche) and Alli (GlaxoSmithKline). It helps prevent the absorption of fat in the gut, but it also causes gastrointestinal side effects. Orlistat was recently used in an attempt to accelerate the elimination of a dioxin derivative from a poisoning victim.
