Phentermine
Phentermine, sold under the brand name Adipex-P among others, is a medication used together with diet and exercise to treat obesity. It is available by itself or as the combination phentermine/topiramate. Phentermine is taken by mouth. Common side effects include a fast heart beat, high blood pressure, trouble sleeping, dizziness, and restlessness. Serious side effects may include abuse, but do not include pulmonary hypertension or valvular heart disease, as the latter complications were caused by the fenfluramine component of the " fen-phen" combination. Phentermine is a norepinephrine and dopamine releasing agent (NDRA) and produces stimulant, rewarding, and appetite suppressant effects. Chemically, it is a substituted amphetamine. Phentermine was approved for medical use in the United States in 1959. It is available as a generic medication. In 2022, it was the 149th most commonly prescribed medication in the United States, with more than 3million prescriptions. Ph ...

Fenfluramine
Fenfluramine, sold under the brand name Fintepla, is a serotonergic medication used for the treatment of seizures associated with Dravet syndrome and Lennox–Gastaut syndrome. It was formerly used as an appetite suppressant in the treatment of obesity, but was discontinued for this use due to cardiovascular toxicity before being repurposed for new indications. Fenfluramine was used for weight loss both alone under the brand name Pondimin and in combination with phentermine commonly known as fen-phen. Side effects of fenfluramine in people treated for seizures include decreased appetite, somnolence, sedation, lethargy, diarrhea, constipation, abnormal echocardiogram, fatigue, malaise, asthenia, ataxia, balance disorder, gait disturbance, increased blood pressure, drooling, excessive salivation, fever, upper respiratory tract infection, vomiting, appetite loss, weight loss, falls, and status epilepticus. Fenfluramine acts as a serotonin and norepinephrin ...

Fenfluramine/phentermine
The drug combination fenfluramine/phentermine, usually called fen-phen, is an anti-obesity medication that is no longer widely available. It was sold in the early 1990s, and utilized two anorectics. Fenfluramine was marketed by American Home Products (later known as Wyeth) as ''Pondimin'', but was shown to cause potentially fatal pulmonary hypertension and heart valve problems, which eventually led to its withdrawal in 1997 and legal damages of over $13 billion.Avorn J. (2004). ''Powerful Medicines'', pp. 71-84. Alfred A. Knopf. On the other hand, phentermine has side effects such as a fast heart beat, high blood pressure, trouble sleeping, dizziness, and restlessness. Fenfluramine acts as a serotonin releasing agent, phentermine as primarily a norepinephrine releasing agent. Phentermine also induces the release of serotonin and dopamine, although to a far lesser extent than it induces the release of norepinephrine. History Fenfluramine as a single drug was first introduc ...

Phentermine/topiramate
Phentermine/topiramate, sold under the brand name Qsymia, is a combination drug of phentermine and topiramate used to treat obesity. It is used together with dietary changes and exercise. If less than 3% weight loss is seen after 3 months it is recommended the medication be stopped. The weight loss is modest. Effects on heart related health problems or death is unclear. Common side effects include tingling, dizziness, trouble sleeping, and constipation. Serious side effects may include suicide, abuse. Use is not recommended during pregnancy. Phentermine is a stimulant and appetite suppressant. Topiramate is an anticonvulsant that has weight loss side effects. The exact mechanism of action for both drugs is unknown. Phentermine/topiramate was approved for medical use in the United States in 2012. In October 2012, approval was denied in Europe, due to concerns regarding safety. Medical uses In clinical trials, people treated with the highest dose of phentermine/topiramate ER ...

Substituted Amphetamine
Substituted amphetamines, or simply amphetamines, are a chemical class, class of compounds based upon the amphetamine structure; it includes all derivative (chemistry), derivative compounds which are formed by replacing, or substitution reaction, substituting, one or more hydrogen atoms in the amphetamine core structure with substituents. The compounds in this class span a variety of pharmacological subclasses, including stimulants, Empathogen-entactogen, empathogens, and hallucinogens, among others. Examples of substituted amphetamines are amphetamine (itself), methamphetamine, ephedrine, cathinone, phentermine, mephentermine, tranylcypromine, bupropion, methoxyphenamine, selegiline, amfepramone, amfepramone (diethylpropion), pyrovalerone, MDMA (ecstasy), and 2,5-dimethoxy-4-methylamphetamine, DOM (STP). Some of amphetamine's substituted Derivative (chemistry), derivatives occur in nature, for example in the leaves of ''Ephedra (genus), Ephedra'' and khat plants. Amphetamine w ...

Obesity
Obesity is a medical condition, considered by multiple organizations to be a disease, in which excess Adipose tissue, body fat has accumulated to such an extent that it can potentially have negative effects on health. People are classified as obese when their body mass index (BMI)—a person's weight divided by the square of the person's height—is over ; the range is defined as overweight. Some East Asian countries use lower values to calculate obesity. Obesity is a major cause of disability and is Obesity-associated morbidity, correlated with various diseases and conditions, particularly cardiovascular diseases, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis. Obesity has individual, socioeconomic, and environmental causes. Some known causes are Western pattern diet, diet, low physical activity, automation, urbanization, quantitative trait locus, genetic susceptibility, medications, mental disorders, Economic policy, economic pol ...

Psychostimulant
Stimulants (also known as central nervous system stimulants, or psychostimulants, or colloquially as uppers) are a class of drugs that increase alertness. They are used for various purposes, such as enhancing attention, motivation, cognition, mood, and physical performance. Some stimulants occur naturally, while others are exclusively synthetic. Common stimulants include caffeine, nicotine, amphetamines, cocaine, methylphenidate, and modafinil. Stimulants may be subject to varying forms of regulation, or outright prohibition, depending on jurisdiction. Stimulants increase activity in the sympathetic nervous system, either directly or indirectly. Prototypical stimulants increase synaptic concentrations of excitatory neurotransmitters, particularly norepinephrine and dopamine (e.g., methylphenidate). Other stimulants work by binding to the receptors of excitatory neurotransmitters (e.g., nicotine) or by blocking the activity of endogenous agents that promote sleep (e.g., ca ...

Appetite Suppressant
An anorectic is a drug that reduces appetite, resulting in lower food consumption, leading to weight loss. These substances work by affecting the central nervous system or certain neurotransmitters to create a feeling of fullness or reduce the desire to eat. The understanding of anorexiant effects is crucial in the development of interventions for weight management, eating disorders, and related health concerns. The anorexiant effect can be induced through diverse mechanisms, ranging from hormonal regulation to neural signaling. Ghrelin, leptin, and peptide YY are among the hormones involved in appetite control. Additionally, neurotransmitters such as serotonin and dopamine in the central nervous system contribute significantly to the regulation of food intake. By contrast, an appetite stimulant is referred to as orexigenic. The term is (from the Ancient Greek language, Greek and ), and such drugs are also known as anorexigenic, anorexiant, or appetite suppressant. History Us ...
