Diethylpropion is a sympathomimetic stimulant drug marketed as an appetite suppressant. Chemically, it is the N,N-diethyl analog of cathinone. Its mechanism of action is similar to other appetite suppressants such as sibutramine, phentermine and dextroamphetamine. Diethylpropion is an amphetamine that stimulates neurons to release or maintain high levels of a particular group of neurotransmitters known as catecholamines; these include dopamine and norepinephrine. High levels of these catecholamines tend to suppress hunger signals and appetite.

Diethylpropion (through catecholamine elevation) may also indirectly affect leptin levels in the brain. It is theorized that diethylpropion can raise levels of leptin which signal satiety. It is also theorized that increased levels of the catecholamines are partially responsible for halting another chemical messenger known as neuropeptide Y. This peptide initiates eating, decreases energy expenditure, and increases fat storage. It is used in the management of exogenous obesity as a short-term adjunct (a few weeks) in a regimen of weight reduction based on caloric restriction.

Weight Loss drugs, supplements, and products have been growing rapidly in recent years with hundreds of different options now readily available throughout the dieting industry. These products generally come with a minimal risk to your health and can have enormous health benefits for the user, and when combined with regular exercise and a healthy, well-balanced diet, it can become extremely easy to obtain and keep your ideal figure. However, some people still struggle to reach their goals with tried and tested methods and may need to consider prescription medications, this can be for a wide range of reasons. Diethylpropion is a prescription medication.

Diethylpropion is classed as a sympathomimetic and central nervous system stimulant drug. It is known by many other trade names and is marketed as an appetite suppressant, however, Diethylpropion is usually only approved on a short-term basis to help manage obesity in patients with an initial body mass index (BMI) of greater than 30 kg. It is prescribed in combination with a calorie restrictive diet for patients who have not responded to a regimen of diet and/or exercise alone.

Diethylpropion acts as an appetite-suppressant by reducing hunger sensation levels within patients. It can also increase blood pressure and stimulate the central nervous system. This can, in turn, potentially increase the patient's metabolic rate allowing them to burn fat at a higher rate than normal, however, this is usually combined with a calorie restrictive diet.

The purpose of a calorie restrictive diet in combination with this type of drug is to encourage the body to turn to its natural stores of fat to provide energy for the body throughout the day. This is ultimately what Diethylpropion actually does. Diethylpropion stimulates neurons in the brain to release and maintain high levels of catecholamines which are hormones produced by the adrenal glands, which sit on top of the kidneys including dopamine and norepinephrine resulting in a suppression of hunger signals and appetite.

Diethylpropion is used as a short-term weight loss aid to help treat obesity. It works by suppressing the appetite and is meant to be used in combination with an appropriate diet. Diethylpropion, which comes in short-acting and long-acting tablet form, is available by prescription only. While most people tolerate the drug well, potential side effects include insomnia, restlessness, nausea, and shakiness. Diethylpropion hydrochloride (Tenuate) is a prescription weight loss medication approved to treat obesity for short-term use only (just a few weeks). It should be used along with an appropriate diet and exercise. Do not take diethylpropion more often or at higher doses than prescribed, as this can lead to addiction or dependence.
