NCIt definition : The hydrochloride salt form of phentermine, a sympathomimetic amine with central nervous
system (CNS) stimulant and appetite depressant properties. Phentermine hydrochloride
stimulates the release of norepinephrine and dopamine from nerve endings and blocks
the reuptake of these monoamines at the neuronal junctions, resulting in CNS stimulation
and metabolic effects, including appetite-suppression, decreased gastric acid secretion
and increased blood pressure.;
