What are the medicine prescribed for parkinson disease?

Complicated. With the earliest symptoms, best approach is Dopamine agonist (mirapex, requip), later l-dopa, which remains fundamental, and maybe Azilect for potential protection. As the l-dopa becomes less efficacious, comtan, (entacapone) and even later combinations of all of the above, and if inadequate, use of deep brain stimulation.
