Dopamine agonists are mainly used in the treatment of Parkinson's disease. [2] The cause of Parkinson's is not fully known but genetic factors, for example specific genetic mutations, and environmental triggers have been linked to the disease. [4]
Dopamine receptors are a class of G protein-coupled receptors that are prominent in the vertebrate central nervous system (CNS) and are implicated in many neurological processes, including motivational and incentive salience, cognition, memory, learning, and fine motor control, as well as modulation of neuroendocrine signaling.

Examples of sympathomimetic effects include increases in heart rate, force of cardiac contraction, and blood pressure. [1] The primary endogenous agonists of the sympathetic nervous system are the catecholamines (i.e., epinephrine [adrenaline], norepinephrine [noradrenaline], and dopamine ), which function as both neurotransmitters and hormones .
Amphetamine, for example, is an indirect agonist of postsynaptic dopamine, norepinephrine, and serotonin receptors in each their respective neurons; [45] [46] it produces both neurotransmitter release into the presynaptic neuron and subsequently the synaptic cleft and prevents their reuptake from the synaptic cleft by activating TAAR1, a ...
For example, Propofol is a GABA agonist, [39] and ketamine is an NMDA receptor antagonist. [40] Performance-enhancement ... Dopamine partial agonists LSD, aripiprazole:
Ecopipam is an example of a D 1-like receptor antagonist. At low doses, dopamine D 2 and D 3 receptor antagonists can preferentially block presynaptic dopamine D 2 and D 3 autoreceptors and thereby increase dopamine levels and enhance dopaminergic neurotransmission.
Many tricyclic antidepressants, tetracyclic antidepressants, antipsychotics, ergolines, and some piperazines like buspirone, trazodone, nefazodone, etoperidone, and mepiprazole antagonize α 1-adrenergic receptors as well, which contributes to their side effects such as orthostatic hypotension.
