SECTION 1: CLINICAL STUDY GUIDE & PHARMACOLOGICAL ANALYSIS
Chapter 1: Antidepressant Pharmacotherapy
Antidepressant medications are a cornerstone of psychiatric care, used to manage major depressive
disorder, dysthymia, and various anxiety disorders. These agents are classified into several distinct
chemical and pharmacological families, each with its own therapeutic index, clinical monitoring
requirements, and adverse effect profile.
Selective Serotonin Reuptake Inhibitors (SSRIs):
SSRIs like fluoxetine, paroxetine, and sertraline are the most commonly prescribed first-line
antidepressants due to their favorable safety profile compared to older agents. SSRIs work by
blocking the reuptake of serotonin at the presynaptic membrane, increasing serotonin availability in
the synaptic cleft. Despite their safety, they have notable side effects that require thorough patient
education:
• Sexual Dysfunction: A prominent and well-documented adverse effect. In male clients, this
frequently manifests as delayed ejaculation or an inability to achieve orgasm (anorgasmia) [15].
Clients should be prepared for a decreased sex drive (libido) and advised to report these changes to
promote adherence [1].
• Appetite and Gastric Changes: During the first few weeks of therapy, SSRIs can cause transient
nausea and a decreased appetite, which can lead to mild weight loss [9].
• Systemic Hypersensitivity: A skin rash can indicate an allergic or systemic hypersensitivity
reaction (such as Stevens-Johnson syndrome or drug-induced vasculitis) and must be reported
immediately to the provider, who will likely discontinue the medication [18].
Tricyclic Antidepressants (TCAs):
TCAs such as amitriptyline and nortriptyline block the reuptake of both norepinephrine and serotonin.
However, they also block histamine, cholinergic, and alpha-1 adrenergic receptors, leading to
significant side effects:
• Cardiovascular and Fall Risks: Alpha-1 adrenergic blockade causes peripheral vasodilation,
resulting in severe orthostatic hypotension. In older adults, this represents a significant fall risk.
Patients must be taught to sit on the side of the bed before standing up in the morning to allow the
cardiovascular system to adjust [8, 22].
• Weight Gain: TCAs cause significant weight gain due to increased appetite and altered metabolic
rates. The nurse's care plan should include weighing the client weekly to monitor for rapid weight
changes [5, 14].
• Anticholinergic Profile: Classic anticholinergic side effects include dry mouth, blurred vision,
urinary retention, and constipation [8].
Monoamine Oxidase Inhibitors (MAOIs):
MAOIs such as phenelzine and selegiline inhibit monoamine oxidase, the enzyme responsible for
breaking down neurotransmitters like norepinephrine, dopamine, and serotonin. MAOIs are reserved

for treatment-resistant depression due to their narrow therapeutic index and lethal interactions:
• Dietary Tyramine Restriction: Ingesting tyramine-rich foods (e.g., aged cheeses, cured meats like
salami, draft beer, and overripe fruits) while taking MAOIs can cause a rapid accumulation of
norepinephrine, leading to a life-threatening hypertensive crisis [3, 9].
• Transdermal Administration: Transdermal selegiline is applied daily to clean, dry, intact skin on
the upper thigh, outer upper arm, chest, or back [17]. Hair at the site should be clipped (not shaved)
to prevent irritation [17].
• Washout Period: To prevent serotonin syndrome (characterized by cognitive changes, autonomic
instability, and neuromuscular hyperactivity), a 5-week washout period is required after discontinuing
fluoxetine before starting an MAOI [50].
Atypical Antidepressants:
• Bupropion: A norepinephrine-dopamine reuptake inhibitor (NDRI). Its unique mechanism does not
affect serotonin, meaning it does not cause sexual dysfunction or weight gain. It is highly effective as
a smoking cessation aid (marketed as Zyban) by reducing cravings and the physical urge to smoke
[1, 2]. However, it can lower the seizure threshold.
• Trazodone: Frequently prescribed for depression-associated insomnia due to its sedative effects. It
carries a black box warning regarding increased suicidal ideation and behavior in children,
adolescents, and young adults [15].
Chapter 2: Mood Stabilizers & Antimanic Therapy
Mood stabilizers are the primary pharmacotherapy for bipolar disorder, aimed at reducing acute
manic or depressive episodes and preventing future mood swings.
Lithium Carbonate:
Lithium is a naturally occurring salt that is highly effective in managing acute manic episodes and
maintenance therapy. It has an extremely narrow therapeutic index, with therapeutic serum levels
ranging from 0.6 to 1.2 mEq/L (up to 1.5 mEq/L during acute mania). Close laboratory monitoring of
serum levels is a standard of care [11].
• Mechanism of Toxicity: Lithium is handled by the kidneys in a manner similar to sodium. Any
factor that decreases sodium levels or causes dehydration (e.g., severe vomiting, diarrhea,
low-sodium diets, or excessive sweating from running 4 miles outdoors in the afternoon) will cause
the kidneys to retain lithium, rapidly pushing serum levels into the toxic range [4, 5, 13].
• Signs of Toxicity: A serum level of 1.8 mEq/L or higher indicates clinical toxicity [11, 12]. Early
neurological indicators include blurred vision and ataxia (incoordination) [18]. If these signs are
observed, the nurse must immediately withhold the next dose, assess the client, and obtain a serum
lithium level [18].
• Patient Education: Clients must be taught to maintain consistent fluid intake (2-3 liters/day) and
stable dietary sodium levels, and to report any signs of fluid loss (such as vomiting or diarrhea)
immediately [4].
Anticonvulsant Mood Stabilizers:

Anticonvulsants like carbamazepine and valproic acid are excellent alternatives or adjuncts to lithium,
particularly for rapid-cycling bipolar disorder [6]. Carbamazepine is highly effective in reducing manic
episodes [6], but it carries a risk of serious bone marrow suppression. This can manifest as
leukopenia, thrombocytopenia, and aplastic anemia, making a baseline and periodic complete blood
count (CBC) a mandatory monitoring requirement [49].
Chapter 3: Antipsychotic Pharmacotherapy & Motor Side Effects
Antipsychotics are used to manage positive and negative symptoms of schizophrenia and other
psychotic disorders. They are divided into first-generation (typical) and second-generation (atypical)
agents.
First-Generation Antipsychotics (FGAs):
FGAs like haloperidol, thioridazine, and chlorpromazine primarily block dopamine-2 (D2) receptors in
the brain. While highly effective for positive symptoms (delusions, hallucinations), they carry a high
risk of extrapyramidal symptoms (EPS) and cardiac adverse effects:
• Extrapyramidal Symptoms (EPS): Movement disorders resulting from dopamine blockade in the
basal ganglia. Classic EPS include acute dystonia (severe, painful muscle spasms of the neck, face,
or back), akathisia (fidgeting, motor restlessness), and pseudoparkinsonism (hand tremors, drooling,
shuffling gait) [13, 28]. Acute dystonia is a distressing emergency reversable with anticholinergics like
benztropine IM [2] or diphenhydramine PO [6, 18].
• Cardiac Dysrhythmias: High-potency typical antipsychotics like haloperidol are associated with
QTc interval prolongation, which can precipitate fatal ventricular dysrhythmias [2].
• Anticholinergic Effects: Phenothiazines like chlorpromazine have high anticholinergic activity,
commonly causing dry mouth, blurred vision, and urinary retention [8]. To treat gastric irritation,
patients can take oral doses with food or a glass of milk [16, 17]. Because they can cause central
nervous system depression, respiratory rate and depth must be monitored every 4 hours [11, 30].
• Agranulocytosis Risk: Thioridazine can cause severe, life-threatening leukopenia. Patients must
report any early signs of infection, such as fever or sore throat, immediately [7].
Second-Generation Antipsychotics (SGAs):
SGAs like clozapine, olanzapine, risperidone, aripiprazole, and quetiapine block both dopamine and
serotonin receptors. They have a lower risk of EPS but cause significant metabolic and specific
system side effects:
• Metabolic Syndrome: Rapid weight gain (e.g., 3 lbs in 2 weeks) and hyperlipidemia are common
with olanzapine and risperidone [13, 17]. Dietary counseling is essential.
• Clozapine Restriction: Clozapine is reserved for refractory schizophrenia due to a high risk of
severe agranulocytosis. Therapy is contraindicated if the baseline white blood cell (WBC) count is
below 3,500/mm³ or the absolute neutrophil count (ANC) is below 2,000/mm³ [9]. Weekly blood
monitoring is required.
• Risperidone Thermoregulation: Risperidone impairs central thermoregulation, making it difficult
for the body to cool down. Patients must avoid becoming overheated to prevent heatstroke [6]. Before
