What is a D2 agonist?

In Wikidata. A dopamine agonist (DA) is a compound that activates dopamine receptors. There are two families of dopamine receptors, D2-like and D1-like, and they are all G protein-coupled receptors. D1- and D5-receptors belong to the D1-like family and the D2-like family includes D2, D3 and D4 receptors.

What is an example of a dopamine agonist?

Examples of this type of dopamine agonist are bromocriptine, pergolide, lisuride, and the long acting ergoline, cabergoline.

How do D2 agonists work?

Dopamine agonists bind to the D1 and D2 group of dopamine receptors in the brain, copying the effects of the neurotransmitter in order to improve disorders that happen from low levels.

What is the best dopamine agonist?

Dopamine agonists are a class of drug used to treat the symptoms of Parkinson’s disease (PD). Carbidopa-levodopa therapy is the most effective drug available to treat the motor symptoms of PD.

What drugs are dopamine antagonists?

Dopamine antagonist drugs include:

  • Thorazine or Largactil (chlorpromazine)
  • Reglan (metoclopramide)
  • Phenergan (promethazine)
  • Invenga (paliperidone)
  • Risperdal (risperidone)
  • Seroquel (quetiapine)
  • Clozaril (clozepine)

Is D2 receptor inhibitory?

Dopamine D2-like receptors are inhibitory. These receptors couple to Gαi/o to inhibit AC and calcium channels, and activate inhibitory G-protein activated inwardly rectifying potassium channels (GIRK) (Neve et al., 2004, Beaulieu and Gainetdinov, 2011).

What is the function of dopamine D2 receptors?

Signalling through dopamine D2 receptors governs physiological functions related to locomotion, hormone production and drug abuse1,2,3,4,5,6,7. D2 receptors are also known targets of antipsychotic drugs that are used to treat neuropsychiatric disorders such as schizophrenia8.
