TRUE

54

Restless Leg Syndrome (RLS)

—> Prescribed only at night

57
Q

Why does Dopamine do not work with Parkinson’s Disease?

  1. Quickly Metabolize
  2. Does not cross BBB
58
Q

What is the only dopamine antagonist that crosess BBB?

A

Levodopa

59
Q

What is the mechanism action of LEVODOPA?

A

It crosses BBB and it is converted into DOPAMINE

—> IT GETS CONVERTED TO DOPAMINE BEFORE CROSSING BBB

60
Q

Why do we add CARBIDOPA with LEVODOPA?

A

To keep the dose LOW

61
Q

What is the role of CARBIDOPA to LEVODOPA?

A

LEVODOPA GETS CONVERTED (in thw bloodstream) TO DOPAMINE BEFORE CROSSING BBB, CARBIDOPA prevents this from happening

62
Q

What is the advantage of combing Carbidopa and Levodopa?

A

-Lower Dose

-Fewer Side Effects

63
Q

What should you limit when taking Carbidopa/Levodopa?

A

-Protein

-Vitamin B6 (green vegetables, banana, legumes)

-Iron (iron supplements)

—> prevents the absorption of these medications

64
Q

What should you lookout for when taking Carbidopa/Levodopa?

A

O.H

65
Q

Why does Pramipexole and Ropinirole may lead to Schrizophenia?

A

Because they are dopamine antagonist = they increase the level of dopamine

Schrizophenia is caused by too much dopamine!

66
Q

What psychiatric issues a patient may experience while taking dopamine antagosnist?

A

-Paranoia

-Visual Hallucinations

67
Q

What are the RARE side effects of taking Pramipexole and Ropinirole

What are the 2 types of anticholinergic medications used to treat Parkinson’s Dx

A
  1. Benztropine
  2. Trihexyphenidyl
75
Q

Aside from treating Parkinson’s DX, what does anticholinergic medications treat?

A

EPS!

(caused by antipyschotic medications)

76
