Dopaminergic
Dopaminergic means related to the neurotransmitter dopamine. For example, certain proteins such as the dopamine transporter (DAT), vesicular monoamine transporter 2 (VMAT2), and dopamine receptors can be classified as dopaminergic, and neurons which synthesize or contain dopamine and synapses with dopamine receptors in them may also be labeled as dopaminergic. Enzymes which regulate the biosynthesis or metabolism of dopamine such as aromatic L-amino acid decarboxylase (AAAD) or DOPA decarboxylase (DDC), monoamine oxidase (MAO), and catechol O-methyl transferase (COMT) may be referred to as dopaminergic as well. Lastly, any endogenous or exogenous chemical substance which acts to affect dopamine receptors or dopamine release through indirect actions (for example, on neurons that synapse onto neurons that release dopamine or express dopamine receptors) can also be said to have dopaminergic effects, two prominent examples being opioids which enhance dopamine release indirectly in the reward pathways, and amphetamines, which enhance dopamine release directly by binding to, and inhibiting VMAT2.

- Dopamine activity enhancers such as BPAP and PPAP, which are currently only research chemicals, but are being investigated for clinical development in the treatment of a number of medical disorders.
- Vesicular monoamine transporter 2 (VMAT2) inhibitors such as reserpine (Serpasil), tetrabenazine (Nitoman, Xenazine), and deserpidine (Harmonyl), which are used as sympatholytics or antihypertensives, and in the past as antipsychotics.
