Moclobemide Crescent Pharma (Moclobemide)

Moclobemide is indicated for depressive and related mood disorders, acting on the monoamine pathway.

• Major depressive disorder: reduces depressive symptoms and improves mood.
• Social anxiety disorder: alleviates anxiety symptoms in affected individuals.
• Dysthymia (persistent depressive disorder): helps sustain mood stability over long periods.

• Moclobemide reversibly inhibits monoamine oxidase A (MAO‑A), an enzyme responsible for the breakdown of serotonin, norepinephrine and dopamine. By blocking MAO‑A, the drug increases the synaptic concentrations of these neurotransmitters, enhancing mood regulation and alleviating depressive symptoms.

Moclobemide may cause a range of adverse reactions, varying 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, especially with tyramine‑rich foods.
• Liver toxicity: elevated liver enzymes or hepatitis.
• Serotonin syndrome: agitation, hyperthermia, muscle rigidity when combined with serotonergic agents.
• Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis.
• Agranulocytosis: marked reduction in white blood cells.
• Suicidal thoughts: emergence or worsening of suicidal ideation.

When prescribing Moclobemide, clinicians should consider several safety precautions.

• Cardiovascular assessment: evaluate blood pressure and cardiac history before initiation.
• Dietary restrictions: avoid high‑tyramine foods to reduce risk of hypertensive episodes.
• Liver monitoring: check hepatic function prior to and during therapy.
• Psychiatric evaluation: monitor for emergence of mania, hypomania, or suicidal thoughts.
• Drug combination review: ensure no concurrent MAO inhibitors or serotonergic drugs.
• Store at ambient temperature: keep in the original pack, protect from moisture and heat.

Moclobemide interacts with several drug classes; awareness of these interactions helps prevent adverse events.

Major Interactions (Avoid)

• Other monoamine oxidase inhibitors (MAO‑I): risk of severe hypertensive or serotonin syndrome.
• Selective serotonin reuptake inhibitors (SSRIs) and serotonin‑norepinephrine reuptake inhibitors (SNRIs): may precipitate serotonin syndrome.
• Tricyclic antidepressants (TCAs): increased risk of cardiovascular toxicity.
• Meperidine and other opioids: heightened risk of serotonin syndrome.
• Linezolid: potential for serotonin syndrome.

Moderate Interactions (Monitor Closely)

• Sympathomimetic agents (e.g., pseudoephedrine): may raise blood pressure.
• Certain antihypertensives (e.g., clonidine): possible additive hypotensive effect.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs): increased bleeding risk.
• Alcohol: may exacerbate central nervous system depression.
