Phendimetrazine Tartrate (Generic for BONTRIL PDM) decreases your appetite. It is used with a reduced calorie diet and exercise to help you lose weight.
Phendimetrazine is an FDA-approved medication for weight loss, designed for obese adult patients. The main compound is an appetite suppressor and it works as a prodrug to phenmetrazine, one of the main products approved to enhance weight loss. The drug is a derived from phenmetrazine, functioning as a less aggressive version of it.
Both of the drugs act as norepinephrine-dopamine releasing agents (NDRA) and stimulate the central nervous system (CNS), which raises the heart rate and blood pressure in order to meet the purposes of suppressing appetite.Resembling an amphetamine, phendimetrazine enhances weight loss by stimulating the nerves and the brain, which results in an increase of the heart rate and blood pressure, as well as decrease of the appetite. The prescription drug is used as short-term treatment, in combination with an healthy diet and regular physical activity. It should be taken 30 to 60 minutes before the first meal of the day and it is expected to result in a weight loss of about four pounds in the first month of treatment. It is used as short-term treatment for obesity, according to the recommendation of the physician.
Phentermine received the approval of the FDA in 1959 and it remained until 1996 as one of the two drugs available for weight loss. However, phendimetrazine only started to be used in the U.S. for patients who suffer from obesity in 1976, following a rigorous scientific process conducted by the agency. There are currently other available drug treatments for obese patients, but both phentermine and phendimetrazine-based drugs are still therapies with proven success.
Phendimetrazine tartrate tablets are indicated in the management of exogenous obesity as a short term adjunct (a few weeks) in a regimen of weight reduction based on caloric restriction in patients with an initial body mass index (BMI) of 30 kg/m or higher who have not responded to appropriate weight reducing regimen (diet and/or exercise) alone. Phendimetrazine tartrate is indicated for use as monotherapy only. Phendimetrazine tartrate is related chemically and pharmacologically to the amphetamines. Amphetamines and related stimulant drugs have been extensively abused, and the possibility of abuse of phendimetrazine should be kept in mind when evaluating the desirability of including a drug as part of a weight reduction program.
Bontril falls into a class of drugs we call appetite suppressants:
Those can be a very useful addition to a healthy, balanced lifestyle and exercise and eating, but they can't be considered some sort of a magic pill or substitute. The most important thing to keep in mind is this is an FDA-approved drug. It can be prescribed by a physician or other health care provider. But it isn't made for long-term use.
The idea behind appetite suppressants is that you take them during the short-term - several weeks - to give you a little bit of an edge if you're overly hungry when starting a reduced calorie plan. The one thing that I've found is that often people's nutritional balance, if it's made to be a fulfilling diet and they're not over restricting, hunger isn't so much of an issue, so don't think of these as a way to fend off the inevitable hunger of dieting. If you pick a really good, balanced and volumetric meal plan, you may not be so hungry and you may not need to use these types of drugs.
Phendimetrazine is an appetite suppressant that is FDA approved for the treatment of exogenous obesity. It is clinically available anorectic agent, which display minimal interactions with monoamine transporters in vitro. On the other hand, their medications is known to be psychomotor stimulants when administered in vivo as indicated by their shared properties with illicit drugs like cocaine. The following adverse reactions are described, or described in greater detail, in other sections: Primary pulmonary hypertension; Valvular heart disease; Effect on the ability to engage in potentially hazardous tasks; Withdrawal effects following prolonged high dosage administration. Use of phendimetrazine tartrate is contraindicated during or within 14 days following the administration of monoamine oxidase inhibitors because of the risk of hypertensive crisis.

However, elderly patients are more likely to have age-related kidney problems, which may require caution and an adjustment in the dose for patients receiving phendimetrazine extended-release capsules.

Central Nervous System (CNS):
A Phendimetrazine Discussion:
- Phendimetrazine was developed and marketed as a result of the high abuse of phenmetrazine - Preludin. Phendimetrazine, while curbing the appetite, causes very little in the way of the euphoria of Preludin and the classic amphetamines. Tends to feel more like a nervous O.D. of caffeine - especially if taken for psychotropic effects. Some people do, however, find it pleasant enough to abuse it. And like any CNS stimulant, abuse will lead to what has been termed amphetamine psychosis at some point down the road.
Phendimetrazine is chemically related to amphetamines and is a Schedule III drug under the Convention on Psychotropic Substances. Phendimetrazine is a very strong basic compound (based on its pKa). Phendimetrazine is a potentially toxic compound. Phendimetrazine is a weight loss medication. Belongs to the class of organic compounds known as phenylmorpholines.
A stimulant drug used as an appetite suppressant. Phendimetrazine functions as a prodrug to phenmetrazine; approximately 30 percent of an oral dose is converted into it.
Phendimetrazine can essentially be thought of as an extended-release formulation of phenmetrazine with less potential for abuse.Phendimetrazine possesses preferable pharmacokinetics over phenmetrazine as a therapeutic agent because its metabolization by demethylases produces a more steady and prolonged exposure of active drug within the body. This decreases abuse potential as the peak blood-concentration of active phenmetrazine that's produced from a single dose of phendimetrazine is lower than a single therapeutically equivalent dose of phenmetrazine.
