4-Methylamphetamine (4-MA; PAL-313; Aptrol ; p-TAP) is a stimulant and anorectic drug of the phenethylamine and amphetamine chemical classes. In vitro it acts as a potent and balanced serotonin norepinephrine and dopamine releasing agent with Ki affinity values of 53.4nM 22.2nM and 44.1nM at the serotonin norepinephrine and dopamine transporters respectively. However more recent in vivo studies that involved performing microdialysis on rats showed a different trend.
