Anti-obesity medication or weight loss medications are pharmacological agts that reduce or control excess body fat. These medications alter one of the fundamtal processes of the human body, weight regulation, by reducing appetite and consequtly ergy intake, increasing ergy expditure, redirecting nutrits from adipose to lean tissue, or interfering with the absorption of calories.

Weight loss drugs have be developed since the early twtieth ctury, and many have be banned or withdrawn from the market due to adverse effects, including deaths; other drugs proved ineffective. Although many earlier drugs were stimulants such as amphetamines, in the early 2020s, GLP-1 agonists became popular for weight loss.

The drugs semaglutide, naltrexone/bupropion, liraglutide, and orlistat are FDA approved for long-term weight managemt. So far, no drug has be shown to be as effective at long-term weight reduction as bariatric surgery. The main treatmt modalities for obesity remain dieting (healthy diet and caloric restriction) and physical exercise.

The first described attempts at producing weight loss are those of Soranus of Ephesus, a Greek physician, in the second ctury AD. He prescribed elixirs of laxatives and purgatives, as well as heat, massage, and exercise. This remained the mainstay of treatmt for well over a thousand years. It was not until the 1920s and 1930s that new treatmts began to appear. Based on its effectivess for hypothyroidism, thyroid hormone became a popular treatmt for obesity in euthyroid people. It had a modest effect but produced the symptoms of hyperthyroidism as a side effect, such as palpitations and difficulty sleeping.

2, 4-Dinitrophol (DNP) was introduced in 1933; this worked by uncoupling the biological process of oxidative phosphorylation in mitochondria, causing them to produce heat instead of ATP. Overdose caused fatal hyperthermia and DNP also caused cataracts in some users. After the passage of the Food, Drug, and Cosmetic Act in 1938, the FDA banned DNP for human consumption.

Amphetamines (marketed as Bzedrine) became popular for weight loss during the late 1930s. They worked primarily by suppressing appetite, and had other beficial effects such as increased alertness.

This was a combination of multiple pills, all thought to help with weight loss, tak throughout the day. Typical regims included stimulants, such as amphetamines, as well as thyroid hormone, diuretics, digitalis, laxatives, and oft a barbiturate to suppress the side effects of the stimulants.

The FDA approves anti-obesity medications as an adjunctive therapy to diet and exercise for patits for whom lifestyle changes do not result in sufficit weight loss. In the United States, semaglutide (Wegovy) is approved by the FDA for chronic weight managemt.

Some other prescription weight loss medications are stimulants, which are recommded only for short-term use, and thus are of limited usefulness for patits who may need to reduce weight over months or years.

As of 2022, there is no pathway for approval for drugs that reduce fat mass without 5 perct overall weight loss, ev if they significantly improve metabolic health; neither is there one for drugs that help patits maintain weight loss although this can be more challging than losing weight.

As of 2022, no drug has be discovered that would equal the effectivess of bariatric surgery for long-term weight loss and improved health outcomes.
