NCIt definition : An amphetamine derivative and a sympathomimetic stimulant with appetite-suppressant
property. Fenfluramine, which was part of the Fen-Phen anti-obesity medication, stimulates
the release of serotonin from vesicular storage, and modulates serotonin transporter
function. Since serotonin regulates mood and appetite, among other functions, increased
serotonin level results in a feeling of fullness and loss of appetite.;
