Sympathomimetic drugs are substances that mimic the effects of the hormone epinephrine (adrenaline) and the hormome/neurotransmitter norepinephrine (noradrenaline).

Classical sympathomimetic drugs are amphetamines (including MDMA), ephedrine and cocaine, which act by blocking and reversing norepinephrine transporter (NET) activity. NET is a transport protein expressed on the surface of some cells that clears noradrenaline and adrenaline from the extracellular space and into cells, terminating the signaling effects.

Direct stimulation of the α- and β-adrenergic receptors can produce sympathomimetic effects. Albuterol is a very commonly used direct-acting β2-agonist.

Inhibition of norepinephrine metabolism can produce sympathomimetic effects. Norepinephrine is mainly metabolized by the enzyme monoamine oxidase, the monoamine oxidase inhibitor (MAOI) drugs can induce such effects.

Substances like cocaine also affect dopamine, and some substances like MDMA affect serotonin.

Norepinephrine is synthesized by the body into epinephrine, causing central nervous system stimulation. Thus, all sympathimimetic amines fall into the larger group of stimulants (see psychoactive drug chart). Many of these stimulants have therepeutic use and abuse potential, can induce tolerance, and possibly physical dependence.
