Study Notes
Patient Profile
- 53-year-old male with persistent fatigue and lack of motivation
- Currently on fluoxetine for major depressive disorder for 2 months
- Reporting decreased libido and poor concentration affecting work performance
Medical History
- Previous diagnosis: Major depressive disorder
- Other conditions: Hypertension managed with enalapril
- Notable weight gain of 4 kg in 2 months
Symptoms
- Ongoing depressive symptoms despite treatment
- Sexual dysfunction: Recent decrease in libido
- Attention issues leading to difficulties in grading student essays
Pharmacotherapy Considerations
- Adequate trial of fluoxetine (≥6 weeks) shows no significant improvement
- SSRIs are first-line treatments for major depressive disorder but can lead to sexual dysfunction
- An increase in fluoxetine dosage is unlikely to alleviate current symptoms and may worsen sexual side effects
Recommended Treatment Adjustment
- Switch from fluoxetine to bupropion
- Bupropion is a norepinephrine-dopamine reuptake inhibitor
- Does not typically cause sexual dysfunction or weight gain
- May address persistent fatigue and sexual side effects experienced by the patient
Other Treatment Options
- Augmentation strategies (e.g., adding aripiprazole or methylphenidate) are generally considered for partial responses, which does not apply in this case
- Venlafaxine, a serotonin-norepinephrine reuptake inhibitor, also carries a risk of sexual side effects, making bupropion a more suitable option
Key Takeaways
- Switching antidepressants is indicated for patients with inadequate response to previous medications
- The selection of antidepressants should consider existing side effects and patient-specific symptoms
- Bupropion is favored in this scenario due to its lower risk of adverse sexual effects and stimulating properties.
