Q

What D2D interactions are associated with Cholinesterase Inhibitors [Donepezil (Aricept)]?

A

Anticholinergics (first-generation antihistamines, TCAs) reduce effectiveness
NSAIDs, increase risk of GI bleed
antifungals, inhibit metabolism increasing levels

20
Q

What side effect is associated with Cholinesterase Inhibitors [Donepezil (Aricept)]?

A

It may cause dizziness.

21
Q

What is an examples of a NMDA receptor antagonists?

A

Memantine (Namenda)

22
Q

What is the indication for NMDA receptor antagonists [Memantine (Namenda)]?

A

Alzheimer’s Moderate or severe

Helps treat symptoms of AD but no evidence that it modifies the underlying disease process.

23
Q

What is the MOA of NMDA receptor antagonists [Memantine (Namenda)]?

A

Blocks glutamate from excessive excitation of NMDA (glumate excitation is cytotoxic)

24
Q

What side effect is associated with NMDA receptor antagonists [Memantine (Namenda)]?

A

Dizziness – risk for falls.
headache
constipation

25
Q

What D2D interactions are associated with NMDA receptor antagonists [Memantine (Namenda)]?

A

Drugs with memantine and sodium bicarb may have an undesired additive effect.

26
Q

What is an example of a Dopamine replacement?

A

Levodopa & Carbidopa

27
Q

What is the MOA of Dopamine replacements (Levodopa&Carbidopa)?

A

Undergoes conversion to DA in the brain and activates DA receptors (Carbidopa blocks destruction of Levodopa in the periphery.

28
Q

What is the indication for Dopamine replacements (Levodopa&Carbidopa)?

A

Parkinson’s-Good for initial treatment of PD.

First-line drug, or used as a supplement to a dopamine agonist.

29
Q

What side effects are associated with Dopamine replacements (Levodopa&Carbidopa)?

A

n/v, tremor, palpitations, dizziness. Possible psychosis.

30
Q

What patient education should be reviewed with Dopamine replacements (Levodopa&Carbidopa)?

A

*Must avoid high protein meals.

Apomorphine
Ropinirole
Rotigotin

32
Q

What are examples of ergot derivate dopamine agonists?

A

33
Q

What is the indication for dopamine agonists (Apomorphine, Ropinirole, Rotigotin, & Bromocriptine)?

A

It may be used as a supplement to Levodopa.

34
Q

What is theMOA of dopamine agonists (Apomorphine, Ropinirole, Rotigotin, & Bromocriptine)?

A

Hallucinations, sleep attacks, postural hypotension

36
Q
