Indications & Clinical Uses

Montelukast is a leukotriene receptor antagonist used to manage respiratory and allergic conditions.

  • Asthma: reduces frequency of symptoms, improves lung function, and decreases need for rescue inhalers.
  • Allergic rhinitis: alleviates nasal congestion, sneezing, itching and rhinorrhea.
  • Exercise‑induced bronchoconstriction: prevents airway narrowing triggered by physical activity.

How It Works

  • Montelukast selectively blocks the cysteinyl leukotriene receptor CysLT1, inhibiting the binding of leukotriene D4 and related mediators. This antagonism prevents leukotriene‑mediated bronchoconstriction, vascular permeability, and inflammatory cell recruitment in the airways, thereby reducing asthma symptoms and allergic inflammation.

Side Effects

Montelukast is generally well tolerated, but adverse reactions can occur.

Common Side Effects

  • Headache: mild to moderate discomfort.
  • Abdominal pain: occasional stomach upset.
  • Cough: transient irritation.
  • Nausea: occasional queasiness.
  • Diarrhea: loose stools.
  • Fatigue: feeling of tiredness.

Serious or Rare Side Effects

  • Allergic reactions: rash, urticaria, angioedema.
  • Neuropsychiatric events: mood changes, depression, suicidal thoughts.
  • Hepatic enzyme elevation: abnormal liver function tests.
  • Stevens‑Johnson syndrome: severe skin reaction.
  • Anaphylaxis: rare life‑threatening hypersensitivity.

Precautions & Warnings

Before prescribing Montelukast, clinicians should consider several safety aspects.

  • Pregnancy: consult a healthcare provider as safety data are limited.
  • Breastfeeding: use with caution; monitor infant for adverse effects.
  • Hepatic impairment: consider dose adjustment or close monitoring.
  • Concomitant asthma therapy: do not discontinue other controller medications without medical advice.
  • Neuropsychiatric events: monitor patients for mood changes or suicidal ideation.
  • Store at ambient temperature: keep in the original packaging, protect from moisture and direct sunlight.

Avoid Interactions

Montelukast may interact with other medicines, requiring attention to avoid reduced efficacy or increased toxicity.

Major Interactions (Avoid)

  • Rifampin: induces metabolism, lowering montelukast plasma levels.
  • Phenobarbital: may decrease therapeutic effect through enzyme induction.
  • Ketoconazole: can increase montelukast concentrations, raising risk of side effects.

Moderate Interactions (Monitor Closely)

  • Warfarin: may potentiate anticoagulant effect; monitor INR.
  • Beta‑agonists: additive bronchodilation may occur; observe respiratory response.
  • Antidepressants: monitor for enhanced neuropsychiatric symptoms.

Frequently Asked Questions

Montelukast Amarox contains the active ingredient montelukast and is prescribed for the long‑term management of asthma, relief of symptoms of allergic rhinitis, and prevention of exercise‑induced bronchoconstriction in patients for whom these conditions are clinically indicated.

Montelukast works by selectively blocking the cysteinyl leukotriene receptor CysLT1. By preventing leukotrienes from binding to this receptor, it reduces bronchoconstriction, airway edema, and inflammatory cell recruitment, which together help control asthma and allergic airway inflammation.

The appropriate dose of Montelukast Amarox is determined by the prescribing healthcare professional based on the patient’s age, diagnosis, and clinical response. Dosage regimens are individualized and should follow the prescriber’s instructions without deviation.

Safety data for montelukast in pregnancy are limited, so it should only be used if the potential benefit justifies any potential risk to the fetus. During breastfeeding, caution is advised; the drug does pass into breast milk, and a healthcare provider should assess the risk‑benefit balance for the infant.

To place an order, submit an enquiry on the product page at gnhindia.com, specifying the required quantity.

Montelukast belongs to the leukotriene receptor antagonist class, offering an oral alternative to inhaled corticosteroids or long‑acting beta‑agonists. It is particularly useful for patients with aspirin‑sensitive asthma or those who prefer a once‑daily tablet, but it is generally used as an add‑on therapy rather than a sole replacement for inhaled steroids.

Montelukast Amarox should be stored at ambient temperature, below 25 °C. Keep the product in its original container, protect it from moisture, heat, and direct sunlight to maintain stability and potency throughout its shelf life.

Montelukast Amarox is taken orally, usually once daily in the evening, with or without food, as directed by the prescribing clinician. The tablet should be swallowed whole with a glass of water and not crushed or chewed unless specifically instructed.

Serious but rare risks include severe allergic reactions such as rash, angioedema, or anaphylaxis, as well as neuropsychiatric events like depression, mood swings, or suicidal thoughts. Patients should seek immediate medical attention if they experience any of these symptoms.

Montelukast Amarox is contraindicated in individuals with known hypersensitivity to montelukast or any of the tablet’s excipients. Patients with uncontrolled severe asthma should not rely on montelukast alone and must continue prescribed rescue inhalers and controller medications.
