Q

SNRIs MOA

Side effects as a class

A

Selectively block serotonin and norepinephrine

Each one seems to have it’s own SEs, but the class has very few anticholinergic symptoms.

Hyponatremia
Increased bleeding risk

20
Q

Mertazapine:
Class?
SEs?
Unique?

A

Atypical antidepressant: alpha receptor antagonist and serotonin

Great for if depression includes low appetite

Sedative, but only at low doses
Weight gain (increased appetite)
Constipation

21
Q

Bupropion:
Class? NTs?
SEs?

A

Atypical antidepressant: inhibits DA and NOR reuptake

Insomnia
CNS stimulation (anxiety, irritability, psychosis, but also increased concentration, increased energy)
Appetite suppressant

Not good for people with seizure disorders - increases risk.

22
Q

Amitriptyline:
Class?
SEs?

A

TCA

Pretty high side-effects across the board:

  • ACH
  • Sedation
  • Orthostatic hypotension
  • Cardiotoxicity
23
Q

Why do tricyclics cause cardiotoxicity?

A

Because they block sodium and calcium channels, which affects the heart.

24
Q

Why is orthostatic hypotension a common side effect with TCAs and some other antidepressants?

A

Because of the blockade of norepinephrine - affects the blood vessels’ ability to vasoconstrict, especially in the veins.

25
Q

Can you use TCAs in patients with seizure disorders?

A

No, they decrease the seizure threshold.

26
Q

Why do tricyclics cause sedation?

A

Because they also act on histamine receptors.

27
Q

Duloxetine:
Class?
SEs?
Unique?

A

SNRI

Also used for peripheral neuropathy (diabetes), fibromyalgia

Increases BP
Can cause liver toxicity or renal problems: don’t use if there’s severe renal impairment.
Does have anticholinergic effects

(Known as cymbalta)

28
Q

Imipramine:
Class?
SEs?

A

TCA

Standard SEs:
Moderate ACH and sedation
High OH and cardiotoxicity

29
Q

Desipramine:
Class?
SEs?

A

TCA

Low sedation and ACH effects

Moderate OH and cardiotoxicity

30
Q

What would TCA toxicity look like?

Tx?

A

Heart problems: blocks, dysrhythmias, fibrillation, tachycardia

Tx: gastric lavage, activated charcoal, IV sodium bicarbonate.

31
Q

What would you advise a patient experiencing anticholinergic effects?

A 
Chew gum
Wear sunglasses
Eat high fiber foods
Drink 2-3L/day
Void right before taking your meds
32
Q

What class is Tranylcypromine?

A

MAO

33
Q

What class is Phenelzine?

A

MAO

34
Q

What class is Isocarboxazid?

A

MAO

35
Q

What are the most common interactions for MAOIs?

A

OTC decongestants
Antidepressants
Antihypertensives

36
Q

What should you know about switching from or to MAOs?

A

Wait two weeks before starting the next drug

If you’re stopping Prozac, wait 5-6 weeks.

37
Q

Why does a hypertensive crisis happen with MAOs?

A

Tyramine releases accumulated norepinephrine stores: creates massive vasoconstriction and cardiac stimulation.

38
Q

Escitalopram: Class?

A

SSRI

39
Q

What should we warn older adult patients on diuretics who are starting an SSRI?

A

Can cause hyponatremia.

We should obtain baseline serum sodium levels and monitor frequently.

40
Q

Which SNRI is likely to cause anticholinergic effects?

A

Duloxetine

41
Q

What are the first-line agents for depression?

A

SSRIs, SNRIs, bupropion and mirtazapine

42
Q

What would short term remission look like?

A

At least three weeks with no depressed mood/anhedonia and no more than 3 remaining symptoms of depression.

43
Q

How long could it take to see a response? Remission?

A

Up to 8 weeks for a response

Up to 12 weeks for remission

44
Q

Which drug inhibits 1A2?
