Dopamine
Dopamine, a neurotransmitter that transmits impulses between neurons is important for several functions in the brain, involved in motor control and behavioral function. Other neurotransmitters include serotonin, norepinephrine, and acetylcholine.
Sinemet® also known as L-dopa or levodopa therapy, binds directly to the dopamine receptors in the brain.
Dopamine agonists, bind to dopamine receptors in place of dopamine and stimulate those receptors (mimic dopamine). The drugs in this class include:
  • Bromocriptine (Parlodel®)
  • Pergolide (Permax®)
  • Pramipexole (Mirapex®)
  • Ropinirole (Requip®)
  • Dopamine antagonists, drugs that bind but don't stimulate dopamine receptors, which can prevent or reverse actions of dopamine by keeping dopamine from attaching.
