Abnormal dopamine receptor signaling and dopaminergic nerve function is implicated in several neuropsychiatric disorders. [1] Dopamine receptors are therefore common drug targets. Dopamine receptors activate different effectors through not only G-protein coupling, but also signaling through different protein (dopamine receptor-interacting ...
Other dopaminergic drugs that have been used or suggested in the treatment of disorders of diminished motivation include rasagiline (a selective monoamine oxidase B (MAO-B) inhibitor; but see more below), tolcapone (a centrally-acting catechol-O-methyltransferase (COMT) inhibitor), and amantadine (an indirectly acting dopaminergic agent that ...
Serotonin–dopamine releasing agents (SDRAs), for instance 5-chloro-αMT, are less common and are not selective for dopamine release, but have also been developed. [ 9 ] [ 14 ] Tryptamines like 5-chloro-αMT are the only known releaser scaffold that consistently release dopamine more potently than norepinephrine.
DDM can be treated with dopaminergic and other activating medications, such as dopamine reuptake inhibitors, dopamine releasing agents, and dopamine receptor agonists, among others. [1] [2] [3] [11] These kinds of drugs have also been used by healthy people to improve motivation.
The mechanisms of sympathomimetic drugs can be direct-acting (direct interaction between drug and receptor), such as α-adrenergic agonists, β-adrenergic agonists, and dopaminergic agonists; or indirect-acting (interaction not between drug and receptor), such as MAOIs, COMT inhibitors, release stimulants, and reuptake inhibitors that increase the levels of endogenous catecholamines.
Amantadine has dopaminergic effects through uncertain mechanisms of action. [24] [25] It is structurally related to other adamantanes like bromantane and rimantadine, which also have dopaminergic actions. [26] Bromantane can upregulate tyrosine hydroxylase (TH) and thereby increase dopamine production and this might be involved in its ...

However, increased side effects and abuse potential are potential concerns of these agents relative to their SSRI and SNRI counterparts. The SNDRIs are similar to non-selective monoamine oxidase inhibitors (MAOIs) such as phenelzine and tranylcypromine in that they increase the action of all three of the major monoamine neurotransmitters.
