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 ...
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 ...
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 ...
These agents stimulate dopamine receptors. In doing so, they alleviate the symptoms associated with Parkinson's disease . Wikimedia Commons has media related to Dopamine agonists .
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.
Lack of dopamine reuptake and the increase in extracellular levels of dopamine have been linked to increased susceptibility to addictive behavior given increase in dopaminergic neurotransmission. [citation needed] The dopaminergic pathways are considered to be strong reward centers.
A dopamine antagonist, also known as an anti-dopaminergic and a dopamine receptor antagonist (DRA), is a type of drug which blocks dopamine receptors by receptor antagonism. Most antipsychotics are dopamine antagonists, and as such they have found use in treating schizophrenia , bipolar disorder , and stimulant psychosis . [ 1 ]
These adverse effects are more likely during rapid changes between antipsychotic agents, so making a gradual change between antipsychotics minimises these withdrawal effects. [159] The British National Formulary recommends a gradual dose reduction when discontinuing antipsychotic treatment to avoid acute withdrawal symptoms or rapid relapse ...
