Norfenfluramine (3-trifluoromethylamphetamine) is a psychoactive drug which functions as a serotonin releasing agent and potent 5HT2B receptor agonist. The action of norfenfluramine on 5HT2B receptors on heart valves leads to a characteristic pattern of heart failure following proliferation of cardiac fibroblasts on the tricuspid valve, known as cardiac fibrosis.[1] This side effect led to the withdrawal of fenfluramine as an anorectic drug worldwide, and to the withdrawal of benfluorex in Europe[2], as both fenfluramine and benfluorex form norfenfluramine as a metabolite.

Norfenfluramine has also been shown to be vasoactive in its own right, causing pulmonary hypertension.[3][4]
