Q

What patients have ABSOLUTE Contraindications to TCA

Study These Flashcards
A

Cardiovascular disease and history of seizures

21
Q

T/F: If pain is to be blocked then serotonin blockage is required

Study These Flashcards
A

False: If pain is to be blocked then NOREPINEPHRINE should be blocked

22
Q

Which TCAs are active metabolites causing lower incidence of side effects

Study These Flashcards
A

Despiramine and nortriptyline

23
Q

What is the side effects of MAOIs

Study These Flashcards
A

sleep disturbance, ORTHOSTATIC HYPOTENSION, sexual dysfunction, weight gain

24
Q

What are drug-drug interaction consequences when MAO-I are used with other medications, what antibotic can cause this syndrome when administered with MAOI

Study These Flashcards
A

Serotonin syndrome, linezolid

25
Which SSRI adverse effects are transient, not transient
jitteriness, insomnia, GI disturbances/ sexual dysfunction
26
Which SSRI is the safest in pregnancy
Sertraline
27
What can be used as an antidote in serotonin syndrome
Cyproheptadine
28
Since sexual dysfunction is associated with SSRIs what other antidepressants can be given
Bupropion (possible add-on), nefazodone, mirtazipine
29
What are the consequences of abruptly stopping an SSRI, what are the symptoms (Hint: FINISH)
``` Discontinuation Syndrome F: Flu-like syndrome I: Insomnia N: Nausea I: Imbalance S: Sensation of shock in the arms, legs or head H: Hyperarousal ```
30
What are the two antidepressants that MUST be tapered, which SSRI doesn't need to and why
Paroxetine and Venlafaxine, Fluoxetine due to the long half life of the drug and its metabolite (best if adherence is bad)
31
What is the hierachy among SSRIs with regards to insomnia
Fluoxetine (minimize insomnia) -> sertraline -> citalopram -> paroxetine (causes insomnia)
32
Which SSRI have the least amount of drug-drug interactions
Sertraline and Citalopram
33
T/F: SSRIs can work in depression and anxiety
True
34
What class of antidepressants have serotonin reuptake at low doses and more prenounced norepinephrine reuptake inhibition at high doses
Seortonin Norepinephrine Receptor inhibitors (SNRIs)
35
What are adverse effects of Venlafaxine
Increase in blood pressure that isn't clinically significant (unless uncontrolled hypertension), abrupt discontinuation can lead to withdrawal similar to SSRIs. Nausea
36
What is the active metabolite of venlafaxine, what is the advantage of giving it over venlafaxine
Desvenlafaxine, No significant Drug interactions
37
Which SNRI is also used for pain in other diseases (osteoarthritis, diabetic neuropathy)
Duloxetine
38
What are the key points about Trazodone
Little to no sexual dysfunction (antagonist of 5HT-2), orthostatic hypotension, VERY SEDATING, priapism (rare)
39
What atypical antidepressant is associated with heptatoxicity, other facts
Nefazadone/ effective in anxiety and insomnia, LESS sexual dysfucntion
40
What class of medication is an inhibitor of presynaptic dopmamine and NE reuptake, common side effects, contraindication
Bupropion, MOST activation, insomnia, loss of appetite (weight loss), SEIZURES and anorexia
41
T/F:Bupropion improves sexual dysfunction and is effective for treatment of anxiety
False: Bupropion does improve sexual dysfunction BUT is NOT EFFECTIVE for treatment of anxiety due to no interaction with serotonin
42
What receptors does mirtazipine antagonize, what are the effects
5-HT2 receptor antagonism: less AD-induced sexual dysfunction and anxiety 5-HT3 receptor antagonism: improves GI problems such as nausea H1 antagonism: Increased appetite and SEDATION (side effects)
43
T/F: SSRIs and SNRIs have are equally efficacious and are effective for anxiety disorders
True
