Manerix (Moclobemide)

Manerix (moclobemide) is used within the antidepressant drug class to manage depressive conditions.

• Major depressive disorder: reduces depressive symptoms and improves functional capacity in adults.

• Moclobemide reversibly inhibits the enzyme monoamine oxidase A (MAO‑A), preventing the breakdown of serotonin, norepinephrine and dopamine. This increases the synaptic concentrations of these neurotransmitters, enhancing mood regulation and alleviating depressive symptoms without permanent enzyme inactivation.

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

Common Side Effects

• Nausea: mild to moderate stomach upset.
• Headache: transient cranial discomfort.
• Insomnia: difficulty initiating or maintaining sleep.
• Dizziness: sensation of light‑headedness.
• Dry mouth: reduced salivation.
• Constipation: decreased bowel movements.

Serious or Rare Side Effects

• Hypertensive crisis: sudden, severe rise in blood pressure, often after tyramine ingestion.
• Serotonin syndrome: agitation, hyperthermia, neuromuscular abnormalities.
• Severe liver injury: jaundice, elevated hepatic enzymes.
• Agranulocytosis: marked reduction in white blood cells.
• Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis.

Before initiating moclobemide therapy, several safety considerations should be observed.

• Dietary restriction: avoid tyramine‑rich foods to prevent hypertensive episodes.
• Blood pressure monitoring: check regularly, especially after diet changes.
• Liver function assessment: evaluate hepatic enzymes prior to and during treatment.
• Psychiatric evaluation: screen for history of mania or bipolar disorder.
• Discontinuation: taper gradually under medical supervision to reduce withdrawal risk.
• Store at ambient temperature: keep in the original pack, protect from moisture and light.

Moclobemide can interact with various medicines and substances, requiring careful management.

Major Interactions (Avoid)

• Other MAO inhibitors: risk of severe hypertensive or serotonergic events.
• Selective serotonin reuptake inhibitors (SSRIs): may precipitate serotonin syndrome.
• Meperidine or other opioids: increased risk of hypertensive crisis.
• Linezolid: potential for serotonin syndrome.
• Tyramine‑rich foods: can trigger hypertensive emergencies.

Moderate Interactions (Monitor Closely)

• Sympathomimetic agents (e.g., pseudoephedrine): may elevate blood pressure.
• Decongestants (e.g., phenylephrine): monitor cardiovascular response.
• Antihypertensive drugs: possible additive hypotensive effect.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs): watch for bleeding risk.
• Alcohol: may enhance central nervous system depression.
