Q

Larodopa (levodopa) (L-dopa)

A

Precursor of dopamine synthesis

Can cross the blood brain barrier (dopamine can’t)

Q

Sinemet (carbidopa-levodopa)

A

Combination between carbidopa and levodopa to get more levodopa to the brain so more dopamine can be made

Q

You should use sinemet with caution for what type if patients

A

15
Q

Side effects of dopamine agonists

A

Can be severe

Nausea, constipation, headache, orthostatic hypotension, hallucinations

16
Q

Why are dopamine agonist side effects better than dopaminergic drugs if dopamine agonists are more severe

A

Patients respond better because their Parkinson’s symptoms are gone

17
Q

Mirapex (pramipexole)

A

Dopamine agonist

Most common

18
Q

Requip (ropinirole)

A

Dopamine agonist

19
Q

You should use caution when giving dopamine agonist agents to what patients

A

History of orthostatic hypotension (side effect)
Hallucinations
Renal impairment

20
Q

Antiviral medication (and dopaminergic)

A

Increase release of dopamine from nerve terminals

Blocks reuptake of dopamine

21
Q

Symmetrel (amantadine)

A

Antiviral medication and dopaminergic

22
Q

What kind of cautions should you take when giving antiviral medications

A

Orthostatic hypotension and seizures

23
Q

Enzyme inhibitors

A

Inhibits enzymes that destroy levodopa and dopamine

24
What are the two kinds of enzyme inhibitors we use
MAOI | COMT inhibitor
25
Side effects of enzyme inhibitors
``` Dyskinesia N/V/D Headache Mental confusion Hallucinations ```
26
Anticholinergics for Parkinson's
Inhibit over activity of acetylcholine Generally act by relieving severe symptoms
27
What do we know about the usage of anticholinergics for Parkinson's
Never used by themselves. Only in adjunct with mirapex or other drugs
28
Cogentin (benztropine mesylate)
Anticholinergics for Parkinson's disease
29
Cogentin is used in conjunction with anti-psychotics. Why?
To treat eps symptoms
