Diet pills and barbiturates are two very different types of drugs. Diet pills are anti-obesity medications that are approved by the US Food and Drug Administration (FDA) as an adjunctive therapy to diet and exercise for people who do not see sufficient weight loss through lifestyle changes alone. Barbiturates, on the other hand, are a type of sedative medication that has been around for over 150 years. They were popular from the early 1900s through the 1970s and were commonly used for sleep and anxiety. While barbiturates have been used in the past as a component of diet pills, they are not diet pills themselves.

What You'll Learn
Diet pills and barbiturates are different
Barbiturates are a class of drugs that act on the central nervous system, while diet pills are typically appetite suppressants, although they may also include stimulants or other types of drugs. Diet pills are intended to aid in weight loss, whereas barbiturates are used for a variety of medical purposes, including the treatment of headaches, insomnia, seizures, and anxiety. While some older diet pills may have contained barbiturates to counteract the side effects of stimulants, modern diet pills typically do not include barbiturates.
The mechanisms of action of diet pills and barbiturates differ significantly. Diet pills often work by blocking or increasing specific hormones, neurotransmitters, or peptides that affect appetite and hunger. For example, some diet pills may target serotonin receptors in the hypothalamus region of the brain to reduce appetite. In contrast, barbiturates act on gamma-aminobutyric acid (GABA), a neurotransmitter that nerves use to communicate with each other, leading to muscle relaxation and reduced nerve activity.
The side effects and risks associated with diet pills and barbiturates also differ. Diet pills may have side effects and can interact with other medications, so it is important to consult a healthcare provider before use. Some diet pills are approved for long-term use, while others are recommended for short-term use only. Barbiturates, on the other hand, can be habit-forming and have a high potential for physical and psychological addiction, as well as overdose. They should be used with caution in combination with other central nervous system depressants to avoid excessive sedation, lethargy, or even coma and death.
In summary, diet pills and barbiturates are distinct types of medications with different purposes, mechanisms of action, and side effects. Diet pills are primarily used for weight loss by suppressing appetite, while barbiturates are central nervous system depressants used for a variety of medical conditions, including headaches, insomnia, seizures, and anxiety. While some older diet pills may have included barbiturates, modern diet pills typically do not, and they should not be considered interchangeable or equivalent.

History of barbiturates
The history of barbiturates began in 1864 when German chemist Adolph von Baeyer (also known as Ludwig von Baeyer) synthesized urea and malonic acid to create barbituric acid. The drug was named after St. Barbara's Day, as it was discovered on the feast day of St. Barbara. However, barbituric acid was found to have poor absorption in the gut and showed little impact on the body.
In 1903, von Baeyer, along with German chemists Josef von Mering and Emil Fisher (also known as von Mering and Fischer), altered the compound to create the first barbiturate, a psychoactive drug that induced sleep. This drug, known as barbital or veronal, was one of the first hypnotic drugs and was used to treat insomnia and anxiety disorders. It was also used in veterinary medicine as an anesthetic drug, and when overdosed, led to a swift and peaceful death.
Over the 20th century, more than 2,500 barbiturates were synthesized, with about 50 of these being used clinically. Some common modifications of the drug led to widely abused drugs in the mid-20th century, such as Amytal, Nembutal, and Seconal. These drugs were often referred to as \"sleeping pills\" and were associated with the overdose deaths of celebrities like Marilyn Monroe and Elvis Presley. Barbiturates were also used to treat seizures, agitation, and sleep problems, and their recreational use increased during the 1960s and 1970s.
However, barbiturates fell out of favor due to their potential for abuse, overdose, and physical and psychological addiction. They have largely been replaced by benzodiazepines and nonbenzodiazepines in routine medical practice, especially in treating anxiety and insomnia, due to the significantly lower risk of overdose. Today, barbiturates are still used for specific purposes, such as general anesthesia, epilepsy treatment, and physician-assisted suicide, but their use is carefully controlled in most countries.

Side effects of barbiturates
Diet pills were historically part of a "rainbow diet pill" regime, which included stimulants, thyroid hormone, diuretics, digitalis, laxatives, and often a barbiturate to suppress the side effects of the stimulants.
Barbiturates are a broad class of drugs called sedatives that have historically been prescribed for the treatment of anxiety, insomnia, and seizures. They can cause a mild sense of euphoria, decreased anxiety, and sleepiness. They are also addictive, and people can become physically dependent on them. Other side effects include:
- Lightheadedness
- Dizziness
- Sedation
- Abdominal pain
- Slowed breathing and heart rate
- Memory problems
- Impaired judgement and coordination
- Irritability
- Paranoia
- Increased sensitivity to sound and pain
- Increased perspiration
- Hallucinations or psychosis
- Emotional instability
- Suicidal ideation
- Slurred speech
Withdrawal from barbiturates can be dangerous and life-threatening, and overdose can result in coma, significant brain and other organ damage, or death.

Diet pills and their side effects
Diet pills, also known as anti-obesity medications, work in several ways to promote weight loss. Some suppress appetite, while others reduce intestinal fat absorption or increase energy expenditure. While these pills can be effective, they often come with side effects that range from mild to severe.
Stimulant-type drugs like phentermine (Adipex-P) can lead to insomnia, increased blood pressure, fast heart rate, restlessness, drug dependence, abuse, and withdrawal symptoms. Amphetamines, which were popular for weight loss in the 1930s, have been associated with harmful side effects, leading to the development of modified versions with reduced stimulatory effects. However, these modified drugs still carry a risk of abuse and are rarely prescribed.
Drugs that interfere with fat absorption, such as orlistat (Alli, Xenical), can cause oily spotting, gas, and soft stools. Orlistat can be used for longer-term weight loss but may lead to frequent oily bowel movements (steatorrhea). Another potential side effect of orlistat is severe liver injury, although this is rare.
Diet pills that affect neurotransmitters in the brain, such as bupropion and naltrexone (Contrave), have been linked to headaches, dry mouth, dizziness, nausea, vomiting, and constipation. GLP-1 receptor agonists like liraglutide (Saxenda) and semaglutide (Wegovy, Ozempic) can cause similar gastrointestinal issues, including diarrhea, upset stomach, heartburn, and gas. These side effects are typically mild and temporary but can impact a patient's comfort and adherence to the medication.
To manage these side effects, patients are advised to make dietary changes, such as limiting high-fat and greasy foods, sugary items, and spicy dishes. Increasing fibre intake can help with constipation, and eating smaller portions can prevent nausea. It is important to note that weight loss medications should be used alongside a low-calorie diet and a doctor-approved exercise plan for the best results.

History of diet pills
Diet pills have been around for thousands of years, with the Greek physician Hippocrates recommending various plants, berries, and natural remedies for weight loss as early as 460–377 BCE. These treatments aimed to induce nausea, vomiting, and diarrhea.
In the late 19th century, thyroid extracts were used for weight reduction, based on the belief that they could boost metabolism and promote weight loss in individuals with normal thyroid function. This approach was not without risks, with side effects including weakness and palpitations.
In the 1930s, dinitrophenol (DNP) emerged as a popular over-the-counter treatment for obesity. It interfered with cells' production of energy, causing the body to burn more energy to compensate. However, this could lead to dangerous increases in body temperature, resulting in organ damage and even death. As a result, DNP was labelled as "extremely dangerous and not fit for human consumption" in 1938.
Amphetamines, marketed as Benzedrine, became popular for weight loss in the late 1930s due to their appetite-suppressing effects and beneficial side effects such as increased alertness. In 1959, the FDA approved phentermine, marking a turning point in modern-day medical treatments for obesity. Phentermine and similar drugs were popular in the 1950s and 1960s, but concerns about cardiovascular risk and abuse potential led to a decline in their use by the early 1970s.
The rainbow diet pill regimen emerged in the 1960s and included amphetamines, thyroid hormones, laxatives, diuretics, and digitalis. However, growing concerns about serious health risks associated with these pills led to stricter regulations and their eventual ban in the US in the late 1960s. Despite this, rainbow diet pills reappeared in South America and Europe in the 1980s.
In the early 2000s, GLP-1 receptor agonists like liraglutide and semaglutide gained popularity for weight loss. These medications are approved by the FDA for weight management in combination with reduced-calorie diets and increased physical activity.
Today, weight loss medications are generally approved for adults with obesity and a body mass index (BMI) of 30 or higher, or adults with a BMI of 27 or higher who have weight-related health issues. While many earlier drugs had limited success and significant side effects, ongoing research and development aim to create better-tolerated and more effective treatments for obesity.
