100%

10
Q

If you start someone on a new seizure drug, do you abruptly stop the other?

A

No.

Down titrate the original and up titrate the new.

Lorazepam (Ativan)

16
Q

Alzheimer’s disease is caused by a ______ deficit in the ______.

A

acetylcholine, hippocampus

17
Q

Therapeutic approach to treating Alzheimer’s:

Inhibit _______ metabolism by inhibiting __________.

A

acetylcholine, acetylcholinesterase

18
Q

Excess glutamate signaling produces increased _____ receptor Ca2+ channel activity

A

NMDA

This then induces secondary cascade leading to neuronal cell death.

19

Donepezil (Aricept)

20
Q

What drug is our NMDA Receptor Antagonist?

A

NMDA Receptor anatagonist

21

Lamotrigine and Phenytoin

22
Q

Parkinson’s disease is caused by loss of _______ cells in the _______ _______.

A

Dopamine, substantia nigra

23
Q

4 main symptoms of Parkinson’s?

A

Tremor, rigidity, bradykinesia, and gait abnormalities.

24
Q

What drug is our anticholinergic for Parkinson’s, and how does it work?

A

Benztropine (Cogentin)

MoA: acetylcholine receptor inhibitor – decreases the imbalance between dopamine and acetylcholine, increasing the amount of dopamine

25
Q

What drug is our NMDA Receptor Inhibitor and how does it work?

A

Amantadine (Symmetrel)

MoA: decreases levodopa injury to NMDA receptor – modulates levodopa impact on NMDA receptors which leads to bradykinesia, rigidity, and tremor

26
Q

What drug is our MAO-B inhibitor and how does it work?

A

Selegiline (Eldepryl)

MoA: inhibits MAO-B enzyme with resulting rise in available dopamine in CNS

27
Q

What really sucks about MAO-B inhibitors?

A

They have a bajillion dx-dx interactions

28
Q

What drug is our dopamine agonist?

A

Ropinrole (Requip)

29
Q

What drug functions as our dopamine replacement?

A

Levodopa/Carbidopa

30
Q

What drug is our COMT inhibitor?

A

Entacapone (Comtan)

31
Q

How does Entacapone work?

A

Decreases levodopa metabolism to 3-OMD allowing more to be metabolized to dopamine

32
Q

MS is an autoimmune disorder that causes CNS __________ and axonal ________

A

demyelination, transection

33
Q

Demyelination leads to the ________ of MS.

Axonal Transection leads to the _______ of MS.

A
