Mazindol is a tricyclic anorexigenic agent unrelated to and less toxic than amphetamine, but with some similar side effects. It inhibits uptake of catecholamines and blocks the binding of cocaine to the dopamine uptake transporter. Mazindol is only approved in the United States for the treatment of Duchenne muscular dystrophy, and is not marketed or available in the United States for use in the treatment of obesity.
Humans and other mammals
Used in short-term (a few weeks) treatment of exogenous obesity in conjunction with a regimen of weight reduction based on caloric restriction, exercise, and behavior modification in patients with a body mass index of 30 kg of body weight per height in meters squared (kg/m<sup>2</sup>) or in patients with a body mass index of 27 kg/m<sup>2</sup> in the presence of risk factors such as hypertension, diabetes, or hyperlipidemia.
Mazindol is a sympathomimetic amine, which is similar to an amphetamine. Mazindol stimulates the central nervous system (nerves and brain), which increases your heart rate and blood pressure and decreases your appetite. Sympathomimetic appetite suppressants are used in the short-term treatment of obesity. Their appetite-reducing effect tends to decrease after a few weeks. Because of this, these medicines are useful only during the first few weeks of a weight-loss program.
Mechanism of action
Although the mechanism of action of the sympathomimetics in the treatment of obesity is not fully known, these medications have pharmacological effects similar to those of amphetamines. Unlike other sympathomimetic appetite suppressants such as phentermine, mazindol is thought to inhibit the reuptake of norepinephrine rather than to cause its release.
