D2 receptor agonists
Dopamine agonists have two subclasses: ergoline and non-ergoline agonists. Both subclasses target dopamine D 2 -type receptors. Types of ergoline agonists are cabergoline and bromocriptine and examples of non-ergoline agonists are pramipexole, ropinirole and rotigotine. See more 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 … See more Side effects Dopamine agonists are mainly used to treat Parkinson’s disease but are also used to treat hyperprolactinemia and restless legs syndrome. The side effects are mainly recorded in treatment for Parkinson’s disease where … See more The dopamine receptors are 7-transmembrane domains and are members of the G protein-coupled receptors (GPCR) superfamily. Dopamine receptors have five subtypes, D1 through D5, the subtypes can be divided into two subclasses due to their mechanism of … See more Examples of dopamine agonists include: Partial agonist • Aripiprazole (Partial agonist of the D2 family receptors - Trade name "Abilify" in the United States; atypical antipsychotic) • Phencyclidine (a.k.a.
