A

Lamotrigine

27
Q

Slow taper is ESSENTIAL for this drug

A

Lamotrigine

28
Q

This drug blocks Na channels and opens Cl channels

A

Topiramate

29
Q

Dose related ADRs: drowsiness, parasthesias, psychomotor slowing, weight loss, renal calculi

A

Topiramate

30
Q

It is essential to maintain adequate fluids with this drug in order to lessen the chance of developing renal calculi

A

Topiramate

31
Q

This drug blocks sodium channels, competes for NMDA receptors, prevents AMPA receptor stimulation, and blocks Na channels

A

Felbamate

32
Q

This drug is used for patients with Lennox-Gastaut syndrome

A

Felbamate

33
Q

Non- dose related ADRs include aplastic anemia and liver failure

A

Felbamate

34
Q

Dose related ADRs include anorexia, N/V, insomnia, and HA

A

Felbamate

35
Q

This drug has a favorable PK profile and is available in parenteral form. You would need to adjust the dose for renal insufficiency

A

Levetiracetam

36
Q

Side effects include sedation and behavioral abnormalities

A

Levetiracetam

37
Q

This drug is a sulfonamide derivative

A

Zonisamide

38
Q

This drug is renally AND hepatically eliminated

A

Zonisamide

39
Q

Dose related ADRs: sedation, dizziness, cognitive impairment, nausea

A

Zonisamide

40
Q

Non-dose related ADRs: rash, oligohydrosis, kidney stones

A

Zonisamide

41
Q

This drug is never used alone for seizures, but rather used as an adjunctive treatment for partial onset seizures

A

Pregabalin

42
Q

This drug is often used for peripheral neuropathy, postherpetic neuralgia, and fibromyalgia

A

Pregabalin

43
Q

Side effects include dizziness, somnolence, dry mouth, peripheral edema, blurred vision, and weight gain

A

Pregabalin

44
Q

This class of drug is first choice for SE

A

Benzodiazepines: Lorazepam or Diazepam

45
Q

Besides benzos, what else can be used to treat SE?

A

Hydantoins (Fosphenytoin or phenytoin)

Barbituates (Phenobarbital)

46
Q

This class of drugs act as positive allosteric modulators by enhancing channel gating in the presence of GABA

A

benzos

47
Q

ADRs include: infusion rate related arrhythmias and hypotension, respiratory depression, and impairment of consciousness

A

benzos

48
Q

This is the DOC in SE patients with IV access

A

Lorazepam

49
Q

True or false: Diazepam is preferred over lorazepam for the treatment of SE secondary to duration of action

A

FALSE. Lorazepam DOA is 12-24 hours, whereas Diazepam DOA is 15 min to 2 hours

50
Q

This class of drug is second line therapy for SE. It has less CNS and respiratory depression than benzos and barbs

A

Hydantoins

51
Q

This class of drugs can cause arrhythmias, nystagmus, dizziness, and ataxia

A

Hydantoins

52
Q

H2O soluble prodrug of phenytoin

A

Fosphenytoin

53
Q

This drug is highly lipophilic and quickly redistributes out of the brain to other fat stores in the body

A

Diazepam

54
Q

True or false: fosphenytoin contains propylene glycol

A

FALSE. Phenytoin does

55
Q

This drug is 3rd line agent for SE if sz persists despite 2-3 doses of benzos and a loading dose of hydantoin

A

Phenobarbital

56
Q

This drug is 2nd line agent for SE if sz persists after 2-3 doses of benzos and hydantoins are contraindicated

A

Phenobarbital

57
Q

ADRs include: more CNS and respiratory depression than hydantoins

A

Phenobarbital

58
Q

True or False: Phenobarbital contains proplyene glycol

A

TRUE

59
Q

These are 3 AEDs that cause prolonged inactivation of the voltage-sensitive sodium channel

A

Phenytoin
Carbamazepine
Lamotrigine

60
Q

These drugs (3) DIRECTLY enhance GABA-mediated inhibition

A

BZDP
Barbs
Topiramate (we think)

61
Q

These drugs (3) INDIRECTLY enhance GABA- mediated inhibition

A

Gabapentin
Tiagabine
Vigabatrin

62
Q

These 2 drugs reduce glutaminergic excitation

A

Phenobarbital

Topiramate

63
Q

This drug has an extraordinarily long half life and time to steady state

A

Phenobarbital

64
Q

This drug is a benzo used for refractive SE

A

Midazolam (Versed)
