<unk>  is a sympathomimetic amine and is classified as an anorectic. The drug's main function is to reduce appetite, which in turn reduces caloric intake. Although the mechanism of action of the sympathomimetic appetite suppressants in the treatment of obesity is not fully known, these medications have pharmacological effects similar to those of amphetamines. Amphetamine and related sympathomimetic medications (such as<unk>  are thought to stimulate the release of norepinephrine and/or dopamine from storage sites in nerve terminals of the lateral hypothalamic feeding center, thereby producing a decrease in appetite. This release is mediated through the binding of<unk>  to VMAT2 and inhibiting its function, causing a release of these neurotransmitters into the synaptic cleft through their reuptake transporters. Tachyphylaxis and tolerance have been demonstrated with all drugs of this class.<unk>  has a half-life of 4–6 hours.
