Phendimetrazine is a phenylalkylamine sympathomimetic amine with pharmacological activity similar to the prototype drugs of this class used in obesity, the amphetamines. Actions include central nervous system stimulation and elevation of blood pressure. Tachyphylaxis and tolerance has been demonstrated with all drugs of this class in which these phenomena have been looked for. Drugs of this class used in obesity are commonly known as ''anorectics or anorexigenics." It has not been established, however, that the action of such drugs in treating obesity is primarily one of appetite suppression. Other central nervous system actions or metabolic effects, may be involved.
- Mechanism of action
Phendimetrazine may act in a similar way to amphetamines in that it activates the alpha-adrenergic system to induce an appetite suppressive and metabolic increase effect. The drug also acts as a norepinephrine-dopamine releasing agent (NDRA). It can bind to and reverse the NET.
Target Actions Organism AAlpha-1A adrenergic receptor agonistHumans ASodium-dependent noradrenaline transporter negative modulatorHumans UAlpha-1B adrenergic receptor agonistHumans - Absorption
Peak plasma levels occur within 1 to 3 hours. Absorption is usually complete by 4 to 6 hours.

- Protein binding

- Metabolism
Approximately 30% of a given dose of phendimetrazine is metabolized into phenmetrazine, which may account for part of its anorectic effect, and probably also influences abuse potential; individuals who metabolise a greater proportion of phendimetrazine into phenmetrazine are more likely to develop problems with dependence and addiction

Acute overdosage of phendimetrazine may manifest itself by the following signs and symptoms: unusual restlessness, confusion, belligerance, hallucinations, and panic states. Fatigue and depression usually follow the central stimulation. Cardiovascular effects include arrhythmias, hypertension, or hypotension and circulatory collapse. Gastrointestinal symptoms include nausea, vomiting, diarrhea, and abdominal cramps. Poisoning may result in convulsions, coma and death.
