Dopamine agonists, Anticholinergic agents, COMT-Inhibitors, MAO-I's

3

All patients with PD should avoid what type of medications?

Dopamine antagonists (i.e. conventional antipsychotics, some atypical antipsychotics (risperidone, ziprasidone, olanzapine), metoclopramide, and phenothiazines (including promethazine and prochlorperazine)

4

If a patient with PD needs an antipsychotic agent, what are the best agents to choose?

Quetiapine or Clozapine (neither had D2 antagonism)

5

What is the generic name of Symmetrel?

Amantadine (DA agonist)

6

What is the generic name of Parlodel?

Bromocriptine (DA agonist)

9

What is the generic name of Neupro?

Rotigotine (DA agonist)

10

Apomorphine (DA agonist)

11

13

What are the most common ADRs with Bromocriptine?
