Manerix (Moclobemide)

Moclobemide is used within the antidepressant and anxiety‑disorder therapeutic area to improve mood and reduce depressive or anxious symptoms.

• Major depressive disorder: alleviates core depressive symptoms and improves functional status.
• Social anxiety disorder: reduces excessive fear and avoidance in social situations.
• Persistent depressive disorder (dysthymia): helps sustain mood stability over long periods.

• Moclobemide reversibly inhibits monoamine oxidase A (MAO‑A), an enzyme responsible for breaking down serotonin, norepinephrine, and dopamine. By blocking MAO‑A, the drug increases synaptic concentrations of these neurotransmitters, enhancing mood regulation and reducing depressive and anxiety symptoms without the long-lasting effects of irreversible MAO inhibitors.

Moclobemide may cause a range of adverse reactions, from mild to severe.

Common Side Effects

• Nausea: mild to moderate stomach upset.
• Headache: transient tension‑type headaches.
• Insomnia: difficulty initiating or maintaining sleep.
• Dry mouth: reduced salivation.
• Dizziness: light‑headed sensation, especially on standing.
• Constipation: reduced bowel movements.

Serious or Rare Side Effects

• Hypertensive crisis: sudden high blood pressure, often linked to tyramine intake.
• Serotonin syndrome: agitation, hyperthermia, and neuromuscular abnormalities.
• Severe liver injury: jaundice, elevated liver enzymes.
• Agranulocytosis: marked reduction in white blood cells.
• Psychosis: emergence of hallucinations or delusional thoughts.
• Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis.

Before initiating therapy, clinicians should evaluate patient history and monitor for specific risks.

• Hepatic function: assess liver enzymes prior to and during treatment.
• Blood pressure: monitor regularly, especially when dietary tyramine is consumed.
• Tyramine restriction: advise patients to avoid aged cheeses, cured meats, and fermented products.
• Psychiatric history: screen for bipolar disorder or suicidal ideation.
• Drug interaction review: verify concomitant medications that may potentiate MAO inhibition.
• Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Moclobemide can interact with several drug classes, requiring careful management.

Major Interactions (Avoid)

• Tyramine‑rich foods: risk of hypertensive crisis.
• Selective serotonin reuptake inhibitors (SSRIs): risk of serotonin syndrome.
• Serotonin‑norepinephrine reuptake inhibitors (SNRIs): increased serotonergic activity.
• Tricyclic antidepressants: additive MAO inhibition.
• Linezolid or methylene blue: potent MAO inhibition.

Moderate Interactions (Monitor Closely)

• Non‑steroidal anti‑inflammatory drugs (NSAIDs): heightened bleeding risk.
• Antihypertensives: possible additive blood pressure lowering.
• Carbamazepine: may reduce moclobemide plasma levels.
• Alcohol: may exacerbate central nervous system depression.
• Fluoxetine (if not avoided): moderate increase in serotonergic effects.
