Key Characteristics

• Form: Oral tablets (5 mg, 10 mg, 15 mg, 20 mg) (detailed in Dosage section).

3. Indications and Uses of Vortioxetine

Vortioxetine is indicated for mood and cognitive disorders, leveraging its multimodal action to address depressive symptoms:

• Major Depressive Disorder (MDD): Treats MDD in adults, reducing depressive symptoms (e.g., sadness, anhedonia) and improving quality of life, supported by randomized controlled trials over 8–12 weeks.
• Generalized Anxiety Disorder (GAD): Investigated off-label for GAD, alleviating anxiety and worry, with promising data from psychiatric studies.
• Cognitive Dysfunction in Depression: Enhances cognitive performance (e.g., memory, executive function) in MDD patients, a key differentiator, per neuropsychiatric research.
• Postpartum Depression: Explored off-label to manage postpartum depression, improving maternal mood and bonding, supported by obstetric psychiatry evidence.
• Seasonal Affective Disorder (SAD): Used off-label to address SAD during winter months, reducing seasonal depressive episodes, with emerging data from mood disorder studies.
• Bipolar Depression (Adjunctive): Investigated off-label as an adjunct to mood stabilizers in bipolar depression, stabilizing mood, with cautious use under specialist supervision.
• Chronic Pain with Depression: Employed off-label to treat depression associated with chronic pain (e.g., fibromyalgia), improving pain tolerance, supported by pain management research.
• Social Anxiety Disorder: Explored off-label to reduce social anxiety symptoms in MDD patients, enhancing social functioning, with preliminary psychological data.
• Late-Life Depression: Managed off-label in elderly patients with late-life depression, addressing cognitive decline and mood, per geriatric psychiatry studies.
• Treatment-Resistant Depression (TRD): Investigated off-label in TRD cases, augmenting response when other antidepressants fail, with ongoing clinical trials.

Note: This drug requires careful monitoring for mood changes; consult a healthcare provider for tailored therapy and resistance management.

4. Dosage of Vortioxetine

Important Note: The dosage of this antidepressant must be prescribed by a healthcare provider. Dosing varies by patient response, tolerability, and clinical goals, with adjustments based on therapeutic evaluation.

Dosage for Adults

  • Initial: 10 mg once daily, taken with or without food.
  • Maintenance: Adjust to 5 mg, 15 mg, or 20 mg once daily based on response, maximum 20 mg/day.
• Cognitive Dysfunction in MDD:
  • 10–20 mg once daily, titrated for optimal cognitive benefit.

Dosage for Children

• Not Approved: Not recommended for patients under 18 years due to insufficient safety data; off-label use requires pediatric psychiatry supervision.

Dosage for Pregnant Women

Dosage Adjustments

• Renal Impairment: No adjustment needed; monitor in severe cases (CrCl <30 mL/min).
