'''Methylnaphthidate''' (also known as '''HDMP-28''') is a novel synthetic [[psychoactive class::stimulant]] substance of the substituted [[chemical class::naphthidate]] and [[piperidine]] chemical classes. It is a structural analog of the commonly prescribed ADHD drug [[methylphenidate]] (e.g. ''Ritalin'', ''Concerta'') that produces moderately [[stimulating]] effects when [[Routes of administration|administered]].

Like members of the [[phenidate]] class, methylnaphthidate is believed to act as a [[monoamine]] [[reuptake inhibitor]].{{citation needed}} However, it has been reported to display distinct differences in its subjective effects by not behaving as a traditional [[dopaminergic]] [[stimulant]]. This has been speculated to owe itself to its appreciable effects on [[serotonin]] reuptake inhibition that is not observed in typical methylphenidate analogs.{{citation needed}}

The main structural differences between methylnaphthidate and methylphenidate in chemical substance is the replacement of the core phenyl ring with with a napthalene group.

The effects which occur during the [[offset]] of a [[stimulant]] experience generally feel negative and uncomfortable in comparison to the effects which occurred during its [[peak]]. This is often referred to as a "comedown" and occurs because of [[neurotransmitter]] depletion. Its effects commonly include:
*'''[[Effect::Anxiety]]'''
*'''[[Effect::Cognitive fatigue]]'''
*'''[[Effect::Depression]]'''
*'''[[Effect::Irritability]]'''
*'''[[Effect::Motivation suppression]]'''
