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.
Numerous clinical trials have been performed to assess the use of dopamine agonists for the treatment of restless legs syndrome (RLS). RLS is identified by the strong urge to move and is a dopamine-dependent disorder. RLS symptoms decrease with the use of drugs that stimulate dopamine receptors and increase dopamine levels, such as dopamine ...

Dopaminergic brain pathways facilitate dopamine-related activity. For example, certain proteins such as the dopamine transporter (DAT), vesicular monoamine transporter 2 (VMAT 2), and dopamine receptors can be classified as dopaminergic, and neurons that synthesize or contain dopamine and synapses with dopamine receptors in them may also be ...
Levodopa (L-DOPA), a prodrug of dopamine which is used to treat Parkinson's disease and certain other conditions. A neurotransmitter prodrug, or neurotransmitter precursor, is a drug that acts as a prodrug of a neurotransmitter. A variety of neurotransmitter prodrugs have been developed and used in medicine.
Fenfluramine is an indirect agonist of serotonin receptors. [2] Fenfluramine binds to the serotonin transporter, blocking serotonin reuptake. However, fenfluramine also acts to induce non-exocytotic serotonin release; in a mechanism similar to that of methamphetamine in dopamine neurons, fenfluramine binds to VMAT2, disrupting the compartmentalization of serotonin into vesicles and increasing ...
For example, the primary endogenous agonist for serotonin receptors is serotonin, and the primary endogenous agonist for dopamine receptors is dopamine. [1] In general, receptors for small molecule neurotransmitters such as serotonin will have only one endogenous agonist, but often have many different receptor subtypes (e.g. 13 different ...
DHE's antimigraine activity is due to its action as an agonist at the serotonin 5-HT 1B, 5-HT 1D, and 5-HT 1F receptors. It also interacts with other serotonin, adrenergic, and dopamine receptors. [14] DHE is an agonist of the serotonin 5-HT 2B receptor and has been associated with cardiac valvulopathy. [15]
