Serotonin–norepinephrine releasing agent

A serotonin–norepinephrine releasing agent (SNRA) is a type of drug which induces the release of serotonin and norepinephrine (and epinephrine) in the body and/or brain. Only a few SNRAs are known, examples of which include norfenfluramine, (R)-MDMA, MBDB, and MDAI. Fenfluramine produces norfenfluramine as a major active metabolite and hence is an SNRA similarly.
