ADVANCED PHARMACOLOGY: PSYCHOPHARMACOLOGY FOR THE
PMHNP REVIEW| QUESTIONS & ANSWERS| GRADE A| 100%
CORRECT (VERIFIED SOLUTIONS)- CHAMBERLAIN
1. 90% of serotonin receptors are in the __________ and _________ are within
the brain - ANS ✓GI tract, only 10%
*which causes GI side effects
2. client education for specific medication classes: SSRI's - ANS ✓Most
adverse effects will subside after 4-5 days once the body adjusts to increased
serotonin levels
3. client education for specific medication classes: SNRI's - ANS ✓-
Medications should not be abruptly stopped to avoid discontinuation
symptoms.
-NE effects of the medication may increase anxiety in some clients. Report worsening
anxiety to the provider.
4. client education for specific medication classes: NDRI's - ANS ✓-Take
medication in the morning.
-Stop taking medication if seizures occur.
-Stop taking medication if anxiety is noted.
5. Other tx options: SARI's - ANS ✓Serotonin Antagonist and Reuptake
Inhibitors
-potently block 5-HT2A and 5HT 2C receptors, allow more 5-HT to interact at
postsynaptic 5-HT1A sites
-Trazodone most common
-adverse effects:
• sedation
• drowsiness
• blurred vision
• constipation
• dry mouth
NR 546
, 2
NR
• severe: priapism (Medical emergency)
Patient education: side effects, take at HS due to sedation
Off-label uses: insomnia, anxiety
6. Mirtazapine (Remeron) - ANS ✓INDICATION
-MDD
Mechanism of Action
-Serotonin norepinephrine receptor agonist, alpha2 receptor agonist. Boosts
neurotransmitters serotonin and norepinephrine/noradrenaline.
TESTS
-Monitor weight and BMI during tx
Starting Dose
-15 mg/day in the evening
Adverse Effects
-Sedation, weight gain, dry mouth, constipation, abnormal dreams, confusion,
hypotension, Changes in urinary function.
Flu-like symptoms may indicate low white blood cell or granulocyte count.
PEARLS
-sedation/drowsiness, useful for clients with insomnia.
-increased appetite/weight gain, useful for clients with depression-related weight
loss
-Precautions: May cause photosensitivity, avoid alcohol (increase sedation)
7. Vilazodone (Viibryd) - ANS ✓INDICATION
-MDD
Mechanism of Action
-Dual-acting serotonin reuptake inhibitor plus 5HT1A partial agonist. Boosts
neurotransmitter serotonin.
TESTS
-None for healthy individuals
Starting Dose
NR 546
, 3
NR
-10 mg/day
Adverse Effects
-Nausea, diarrhea, vomiting, insomnia, dizziness, bruising, sexual dysfunction,
SIADH.
-Rare: Bleeding, hyponatremia.
PEARLS
-Appropriate for depression/comorbid anxiety, action similar to combination of SSRI
and buspirone.
-Precautions: Not approved in children
8. Vortioxetine (Trintellix) - ANS ✓INDICATION
-MDD
Mechanism of Action
-Multimodal antidepressant, Serotonin multimodal (SMM)
-Increases release of serotonin, norepinephrine, dopamine, glutamate, acetylcholine,
and histamine and reduces the release of GABA
TESTS
-None for healthy individuals
Starting Dose
-10 mg/day
Adverse Effects
-nausea, vomiting, constipation, sexual dysfuction.
PEARLS
-Improves depression-related cognition
-Long half-life means vortioxetine can generally be abruptly discontinued.
-Not approved in children
9. Trazodone (Desyrel) - ANS ✓INDICATION
-Depression
Mechanism of Action
-SARI (serotonin 2 antagonist/reuptake inhibitor). Blocks serotonin 2A receptors.
NR 546
, 4
NR
TESTS
-None for healthy individuals
Starting Dose
-150 mg/day in divided doses
Adverse Effects
-dizziness, sedation, hypotension, Nausea, vomiting, edema, blurred vision,
constipation, dry mouth, headache, incoordination, tremor, hypotension, syncope,
occasional sinus bradycardia.
-Rare: rash, priapism.
10. Tricyclic antidepressants - ANS ✓SRI and NRI properties, but they also block
α1-adrenergic, histamine-1, and muscarinic cholinergic receptors
-not used first-line because of the high incidence of adverse effects and the risk of
potential overdose and death
• amitriptyline (Elavil)
• desipramine (Norpramin)
• doxepin (Sinequan)
• imipramine (Tofranil)
• nortriptyline (Pamelor)
11. Alpha-1 adrenergic effects - ANS ✓Orthostatic hypotension
12. Anticholinergic effects - ANS ✓Dry mouth
Blurred vision
Urinary retention
Constipation
13. Histamine effects - ANS ✓Weight gain
Sedation
14. MAOIs - ANS ✓first developed, LAST CHOICE medication class for
depression due to the many potential, serious side effects
-specific dietary restrictions, Foods that contain tyramine should be avoided (Red
wine, Sauerkraut, Cheese, Soy, Smoked meats)
-block enzymes responsible for the breakdown of 5-HT, NE, and DA
• two primary forms of the MAO enzyme: MAO-A and MAO-B
