Antiparkinson

An antiparkinson, or antiparkinsonian, is a type of drug which is intended to treat and relieve the symptoms of Parkinson's disease (PD) or Parkinsonism. Most of these agents act by either increasing dopamine activity or reducing acetylcholine activity in the central nervous system (CNS).

Examples
(Preferred over other medications to prevent undesirable sympathomimetic side effects)
 * Dopaminergic Precursors:
 * Phenylalanine
 * Tyrosine
 * L-DOPA

(To prevent the metabolism of dopamine by MAOB and hence increase its brain levels)
 * Selective monoamine oxidase B inhibitors
 * Selegiline
 * Rasagiline

(Preventing the metabolism of dopamine by COMT and hence increase its brain levels)
 * COMT inhibitors
 * Entacapone
 * Tolcapone

(Directly increase the activity of the dopamine system)
 * Dopamine receptor agonists


 * Apomorphine
 * Bromocriptine
 * Pramipexole
 * Ropinirole
 * Rotigotine


 * Anticholinergics - Antimuscarinics (e.g., Benzatropine): to prevent hyperkinesia.
 * Diphenhydramine
 * Dimenhydrinate
 * Scopolamine
 * Benztropine
