HDEP-28

HDEP-28 or ethylnaphthidate is a stimulant drug of the piperidine and naphthylaminopropane groups, closely related to ethylphenidate, but with the benzene ring replaced by naphthalene. It is even more closely related to HDMP-28, which acts as a potent serotonin–norepinephrine–dopamine reuptake inhibitor with several times the potency of methylphenidate and a short duration of action.^[1] It has been sold as a designer drug since around 2015.^[2]
