usually appears in the first 4 weeks of tx but may also occur as late as 18 months into
tx. It can appear at any dose. Trazodone should be immediately discontinued.

Trazodone can INCREASE the plasma concentration of ______ and _______? -
Answer-Digoxin and phenytoin

What are the indications for nefazodone? - Answer-MDD
panic d/o
GAD
premenstrual dysphoric d/o
chronic pain
PTSD
chronic fatigue syndrome

hepatic function test

What are the TWO characteristic SE of mirtazapine? - Answer-INCREASED appetite
and sedation

What are the most common AE of mirtazapine? - Answer-somnolence

Monitoring of WBCs for pts who develop signs of infection is needed as mirtazapine is
associated with _____ and ___________? - Answer--febrile neutropenia
-agranulocytosis

What are the symptoms of discontinuation syndrome with abrupt withdrawal of
mirtazapine? When would this most likely occur? How long does this typically last? -
Answer-dizziness, lethargy, N/V/D, HA, fever, sweating, chills, malaise, incoordination,
insomnia, vivid dreams, myalgia, paresthesias, dyskinesias, "electric shock like
sensations" visual discoordination, anxiety, irritability, confusion, slow thinking,
hypomania, depersonalization

-most likely occur within 1-7 days after drug stopped. Typically disappears within 3
weeks

Bupropion (Wellbutrin) action? - Answer-bupropion inhibits the reuptake of NE and at
higher doses, DA. This class of medication does not act upon the 5-HT system.
-MOA may involve the presynaptic release of NE and DA

What are the therapeutic indications for bupropion? - Answer-depression
smoking cessation
bipolar d/o
ADHD
cocaine detoxification
hypoactive sexual desire d/o

Discuss the risk of sexual dysfunction, sedation, and discontinuation syndrome for
bupropion? - Answer-Bupropion has a SE profile characterized by a LOW risk of sexual
dysfunction and sedation. NO withdrawal syndrome has been linked to discontinuation
of bupropion.
-bupropion is often added to drugs, such as SSRIs, to counteract sexual SE and may be
helpful as a tx for non-depressed pts with hypoactive sexual desire d/o.

Why is it NOT recommended to prescribe bupropion to pts with severe anxiety or panic
d/o? - Answer-AE include agitation, ANXIETY, irritability, dysphoria, aggression,
hostility, depersonalization, coupled with urges of self-harm or harm to others.

, -pts with severe anxiety + panic d/o should NOT be prescribed bupropion b/c its
potentiating effects on dopaminergic neurotransmission, bupropion can cause psychotic
symptoms including hallucinations, delusions, catatonia, delirium

Discuss potential SE on plasma concentrations with concurrent use of bupropion and
carbamazepine (Tegretol); discuss potential plasma concentration effects with
concurrent use of bupropion and valproic acid (depakene)? - Answer-
carbamazepine(Tegretol) may INCREASE plasma concentrations of bupropion.
bupropion may INCREASE plasma concentrations of valproic acid (depakene)

Dopamine receptor antagonists (DRAs), also known as first generation antipsychotics
(FGAs) and neuroleptics include all of the antipsychotics in which chemical classes? -
Answer-DRAs include all of the antipsychotics in the following groups:
