An increased prevalence of abnormal cardiac valve function, primarily aortic regurgitation, was found on echocardiographic evaluation in patients receiving phentermine in combination with either dexfenfluramine or fenfluramine, both of which act to suppress appetite by increasing serotonergic function; however, an increased prevalence of abnormal cardiac valve function also has been found in patients receiving dexfenfluramine or fenfluramine alone, and the role of phentermine in producing the cardiotoxic effect is uncertain; because of the severity of these cardiovascular effects and because the safety and efficacy of other appetite suppressant combinations have not been established, combined use is not recommended; also, the safety and efficacy of combining as selective serotonin reuptake inhibitor (SSRI), which enhances serotonergic function, with a sympathomimetic appetite suppressant have not been established and combined use is not recommended. /Appetite suppressants, sympathomimetic/

Primary pulmonary hypertension is a rare, frequently fatal pulmonary disease that has been reported with increased frequency in patients receiving anorexigenic agents. One manufacturer of phendimetrazine tartrate ... states that the drug should be used only for short-term management (a few Weeks) of exogenous obesity and should not be used in combination with other anorexigenic agents. /Phendimetrazine tartrate/

Phendimetrazine is contraindicated in patients with hyperthyroidism, moderate to severe hypertension, advanced arteriosclerosis, symptomatic cardiovascular disease, glaucoma, or known hypersensitivity or idiosyncrasy to sympathomimetic amines. The drug is also contraindicated in patients in agitate states or those who are highly nervous, have a history of drug abuse, or are receiving CNS stimulants. Phendimetrazine is contraindicated during or within 14 days of administration of monoamine oxidase (MAO) inhibitors since hypertensive crisis could result.

Central Nervous System Stimulants
A loosely defined group of drugs that tend to increase behavioral alertness, agitation, or excitation. They work by a variety of mechanisms, but usually not by direct excitation of neurons. The many drugs that have such actions as side effects to their main therapeutic use are not included here. (See all compounds classified as Central Nervous System Stimulants.)
Phendimetrazine is readily absorbed from the GI tract and effects persist for about 4 hours after oral administration.

Phendimetrazine is metabolized in the liver by N-demethylation to the active metabolite phenmetrazine. Phenmetrazine is hydroxylated, conjugated, and excreted in the urine.

The elimination half life of phendimetrazine is approximately 9 hours for the sustained release and 2 hours for the regular release preparation. The half life of phenmetrazine is approximately 8 hours.

Phendimetrazine is an effective and widely prescribed appetite suppressant. Preclinical findings show that phendimetrazine displays stimulant properties similar to amphetamine, but few studies have examined the neurochemical mechanism of the drug. ... Phendimetrazine itself had no effect on uptake or release of any transmitter. In contrast, the trans-configured N-demethylated metabolite, phenmetrazine, was a potent releaser of [3H]norepinephrine (EC(50)=50 nM) and [3H]dopamine (EC(50)=131 nM). The cis N-demethylated metabolite, pseudophenmetrazine, displayed modest potency at releasing [3H]norepinephrine (EC(50)=514 nM) and blocking [3H]dopamine re-uptake (IC(50)=2630 nM). All drugs tested were inactive or weak in the [3H]5-HT assays. When injected intravenously, phendimetrazine had minimal effects on extracellular transmitter levels, whereas phenmetrazine produced dose-related elevations in extracellular dopamine. The collective findings suggest that phendimetrazine is a "prodrug" that is converted to the active metabolite phenmetrazine, a potent substrate for norepinephrine and dopamine transporters.
