Curator's Comment: description was created based on several sources, including: https://www.drugs.com/pro/phendimetrazine.html | http://www.wikidoc.org/index.php/Phendimetrazine

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.

Exogenous obesity 19 Sources: http://www.accessdata.fda.gov/drugsatfda_docs/label/2012/018074s034lbl.pdf	Primary		Approved 8429	PHENDIMETRAZINE TARTRATE Approved Use Phendimetrazine tartrate is 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/m2 or higher who have not responded to appropriate weight reducing regimen (diet and/or exercise) alone. Below is a chart of Body Mass Index (BMI) based on various heights and weights. BMI is calculated by taking the patient’s weight, in kilograms (kg), divided by the patient’s height, in meters (m), squared. Metric conversions are as follows: pounds ÷ 2.2 = kg; inches x 0.0254 = meters.

Sample Use Guides

In Vivo Use Guide

One extended-release capsule (105 mg phendimetrazine tartrate) in the morning (30 to 60 minutes before morning meal).

Route of Administration: Oral

In Vitro Use Guide

Racemic phendimetrazine was essentially inactive at [3H]dopamine, [3H]norepinephrine, and [3H]5-HT uptake inhibition and release. The most potent effect of phendimetrazine was inhibition of [3H]norepinephrine uptake, with an IC50 of 8300 nM.
