Serotonin–norepinephrine releasing agent


A serotonin–norepinephrine releasing agent is a type of drug which induces the release of serotonin and norepinephrine in the body and/or brain.
Only a few SNRAs are known, examples of which include norfenfluramine and MBDB. Fenfluramine/phentermine, a combination formulation of fenfluramine, a serotonin releasing agent, and phentermine, a norepinephrine releasing agent, is a functional SNRA that was formerly used as an appetite suppressant for the treatment of obesity.
A closely related type of drug is a serotonin–norepinephrine reuptake inhibitor.
