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."}]
