Indications & Clinical Uses

Montelukast acts on the leukotriene pathway to control chronic airway inflammation and allergic symptoms.

  • Asthma: reduces the frequency of bronchospasm and improves overall asthma control.
  • 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, preventing leukotriene D4 from binding. This inhibition reduces leukotriene‑mediated bronchoconstriction, vascular permeability, and inflammatory cell recruitment in the airways, thereby improving respiratory function and decreasing allergic inflammation.

Side Effects

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

Common Side Effects

  • Headache: mild to moderate intensity.
  • Abdominal pain: occasional discomfort or cramping.
  • Cough: transient dry cough.
  • Dyspepsia: indigestion or upset stomach.
  • Nausea: feeling of queasiness.
  • Fatigue: mild tiredness.

Serious or Rare Side Effects

  • Stevens‑Johnson syndrome: severe skin reactions requiring immediate medical attention.
  • Angioedema: swelling of face, lips or tongue.
  • Hepatic injury: elevated liver enzymes or hepatitis.
  • Neuropsychiatric events: agitation, depression, or suicidal thoughts.
  • Anaphylaxis: acute allergic reaction with airway compromise.
  • Eosinophilic granulomatosis with polyangiitis: rare vasculitic disorder.

Precautions & Warnings

Before prescribing Montelukast, clinicians should consider several safety aspects.

  • Neuropsychiatric monitoring: watch for mood changes, depression or suicidal ideation.
  • Hepatic function: use caution in patients with liver impairment and monitor liver enzymes.
  • Acute asthma: not indicated for immediate relief of bronchospasm; provide rescue inhaler.
  • Elderly patients: assess benefit‑risk ratio due to higher incidence of adverse events.
  • Hypersensitivity: avoid in individuals with known allergy to montelukast or any tablet excipients.
  • Store below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Avoid Interactions

Montelukast may interact with other medicines that affect its metabolism or pharmacodynamic profile.

Major Interactions (Avoid)

  • Phenobarbital: strong enzyme inducer that can lower montelukast plasma levels.
  • Rifampin: induces CYP3A4, potentially reducing therapeutic effect.
  • Ketoconazole: potent CYP3A4 inhibitor that may increase montelukast exposure.

Moderate Interactions (Monitor Closely)

  • Warfarin: possible alteration of anticoagulant effect; monitor INR.
  • Theophylline: may require dose adjustment of theophylline.
  • Beta‑agonists: additive bronchodilator effect; observe for excessive bronchodilation.

Frequently Asked Questions

Montelukast Tecnigen is prescribed to prevent and control chronic asthma, to relieve symptoms of allergic rhinitis such as nasal congestion and sneezing, and to prevent exercise‑induced bronchoconstriction. It works as a maintenance therapy and is not intended for immediate relief of acute asthma attacks.

Montelukast blocks the cysteinyl leukotriene receptor CysLT1, stopping leukotriene D4 from binding. This inhibition reduces bronchoconstriction, airway swelling, and inflammation caused by leukotrienes, leading to improved breathing and reduced allergic symptoms.

The appropriate dose of Montelukast Tecnigen is determined by the prescribing healthcare professional based on the patient’s age, weight, and clinical condition. Patients should follow the prescriber’s instructions and not adjust the dose on their own.

Safety data for montelukast in pregnancy and lactation are limited, and the product is classified as pregnancy category unknown. Healthcare providers should weigh potential benefits against risks and consider alternative therapies when treating pregnant or nursing individuals.

To place an order, submit an inquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

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, though inhaled therapies may provide faster symptom relief in some cases.

Montelukast Tecnigen tablets should be stored below 25 °C in a dry place. Keep them in the original container, protect from moisture and direct sunlight, and keep out of reach of children.

The medication is taken orally, usually once daily in the evening, with or without food. The tablet should be swallowed whole with a glass of water; it should not be crushed, chewed, or split unless specifically instructed by a healthcare professional.

Serious risks include neuropsychiatric events such as depression, agitation, or suicidal thoughts, as well as rare severe skin reactions like Stevens‑Johnson syndrome, angioedema, and hepatic injury. Patients should seek immediate medical attention if they notice any of these symptoms.

Montelukast should be avoided in individuals with known hypersensitivity to montelukast or any of the tablet’s excipients. It is also not suitable for acute asthma attacks, where a rapid‑acting bronchodilator is required.
