Zorluk: KolayPsychopharmacology and Psychological Therapies

A 28-year-old man presents to the psychiatry clinic complaining of severe sadness, fatigue, and loss of interest in his usual hobbies for the past 3 weeks. He reports sleeping up to 14 hours a day and experiencing a significant decline in his appetite. Medical history is notable for an episode two years ago during which he felt "unstoppable," slept only 2 hours per night without feeling tired, and maxed out multiple credit cards on unnecessary purchases. That episode lasted for 10 days and resulted in a brief psychiatric hospitalization. Temperature is 37.0°C (98.6°F), blood pressure is 120/78 mmHg, pulse is 72/min, and respirations are 14/min. On mental status examination, the patient appears disheveled, makes poor eye contact, and exhibits psychomotor retardation. His mood is described as "miserable" and his affect is constricted. He denies suicidal ideation. Which of the following is the most appropriate initial pharmacotherapy for this patient's current symptoms?

  2. B

  3. C
    Venlafaxine

  5. E

Cevap

Quetiapine
The patient is experiencing a major depressive episode but has a distinct history of a manic episode (elevated mood, decreased need for sleep, reckless spending, and hospitalization lasting over 7 days). This presentation confirms a diagnosis of Bipolar I disorder, currently in a depressive phase. The standard of care for bipolar depression includes atypical antipsychotics such as quetiapine or lurasidone, or traditional mood stabilizers like lithium or valproate. Quetiapine is FDA-approved for bipolar depression and is the safest, most effective choice among the options provided.

Adım Adım Çözüm

1
Identify the primary underlying psychiatric disorder based on the patient's history.
The patient has a history of a 10-day episode characterized by elevated mood, decreased need for sleep, impulsivity, and hospitalization, which meets the criteria for a manic episode. This establishes a diagnosis of Bipolar I disorder.
Recognizing the underlying disorder is critical, as treating just the current symptoms without considering the full history can lead to harmful pharmacological choices.
2
Determine the current phase of the patient's illness.
The patient is currently presenting with symptoms of a major depressive episode (depressed mood, anhedonia, hypersomnia, psychomotor retardation).
Pharmacotherapy in bipolar disorder is phase-specific (e.g., acute mania vs. bipolar depression vs. maintenance).
3
Select the safest and most effective evidence-based pharmacotherapy for this specific phase.
Quetiapine is selected. Antidepressant monotherapy is strictly avoided to prevent inducing a manic episode.
Quetiapine, lurasidone, and olanzapine-fluoxetine combination are among the first-line treatments specifically approved for bipolar depression.
