Indications & Clinical Uses

  • Montelukast Sandoz is a leukotriene receptor antagonist used in the management of respiratory and allergic conditions.
  • Asthma (maintenance therapy): improves long‑term control by decreasing bronchial hyper‑responsiveness and reducing the frequency of asthma exacerbations.
  • Allergic rhinitis: alleviates nasal congestion, sneezing and itching by blocking leukotriene‑mediated inflammation in the nasal passages.
  • Exercise‑induced bronchoconstriction: prevents airway narrowing triggered by physical activity in susceptible individuals, supporting better exercise tolerance.

How It Works

  • Montelukast selectively antagonizes the cysteinyl leukotriene receptor CysLT1 located on airway smooth‑muscle cells, mast cells, eosinophils and other inflammatory cells. By blocking this receptor, it inhibits leukotriene‑induced bronchoconstriction, vascular permeability, mucus secretion and inflammatory cell recruitment, thereby reducing airway narrowing and allergic inflammation.

Side Effects

Montelukast may cause a range of adverse reactions, which are categorized by frequency and severity.

Common Side Effects

  • Headache: mild to moderate head pain.
  • Abdominal pain: discomfort in the stomach region.
  • Cough: occasional dry cough.
  • Dyspepsia: indigestion or upset stomach.

Serious or Rare Side Effects

  • Stevens‑Johnson syndrome: severe skin reaction requiring immediate medical attention.
  • Angioedema: rapid swelling of face, lips, tongue or throat.
  • Hepatic injury: signs of liver dysfunction such as jaundice or elevated enzymes.

Precautions & Warnings

When prescribing Montelukast Sandoz, clinicians should consider several precautionary measures to ensure safe use.

  • Assess liver function: evaluate baseline hepatic enzymes, especially in patients with liver disease.
  • Monitor for neuropsychiatric events: watch for mood changes, depression or suicidal thoughts.
  • Use caution in patients with severe asthma: ensure it is part of a comprehensive asthma plan, not a rescue medication.
  • Review concomitant medications: consider potential interactions that may alter drug exposure.
  • Store below 25°C: keep in the original pack, protect from moisture.

Avoid Interactions

Montelukast can interact with other medicines, altering its effectiveness or safety profile.

Major Interactions (Avoid)

  • Ritonavir: may increase montelukast plasma concentrations, raising risk of adverse effects.
  • Phenobarbital: may markedly reduce montelukast levels, compromising efficacy.
  • Ketoconazole: can elevate montelukast exposure, potentially leading to toxicity.

Moderate Interactions (Monitor Closely)

  • Warfarin: montelukast may enhance anticoagulant effect, requiring INR monitoring.
  • Theophylline: concurrent use may increase theophylline levels, necessitating dose adjustment.
  • Beta‑agonists: additive bronchodilatory effect may occur, monitor respiratory status.

Frequently Asked Questions

Montelukast Sandoz is indicated for maintenance therapy of asthma, for relief of symptoms associated with allergic rhinitis, and for prevention of exercise‑induced bronchoconstriction. In each case it helps control airway inflammation and improve breathing comfort when used as part of a comprehensive treatment plan.

Montelukast works by selectively blocking the cysteinyl leukotriene receptor CysLT1. This inhibition prevents leukotrienes from causing bronchoconstriction, mucus production, and inflammatory cell recruitment, thereby reducing airway narrowing and allergic inflammation in the respiratory tract.

The dose of Montelukast Sandoz is set by the prescribing clinician based on the patient’s age, weight, and specific condition. Typical regimens range from 5 mg to 10 mg taken once daily, but the exact amount and timing must follow the prescriber’s order.

Safety data for Montelukast in pregnancy are limited, so it should only be used when the potential benefit outweighs any possible risk to the fetus. Caution is also advised during breastfeeding; a healthcare professional should evaluate the risk‑benefit balance before use.

Submit an enquiry 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 is an oral leukotriene receptor antagonist that targets a specific inflammatory pathway, whereas inhaled corticosteroids act on a broader range of mediators. Montelukast is often used as add‑on therapy or for patients who cannot tolerate inhaled steroids, but it is generally less potent for rapid symptom relief during acute attacks.

Montelukast Sandoz should be stored below 25 °C in a dry place. Keep the tablets in their original container, protect them from moisture and direct sunlight, and avoid exposure to high temperatures to maintain product potency.

The medication is taken orally, usually once daily in the evening, with or without food, as directed by the prescriber. Swallow the tablet whole; do not crush or chew unless specifically instructed by a healthcare professional.

Rare but serious adverse events include severe skin reactions such as Stevens‑Johnson syndrome, angioedema, and hepatic injury. Neuropsychiatric effects, including mood changes, depression, or suicidal thoughts, have also been reported and require prompt medical evaluation.

Patients with a known hypersensitivity to montelukast or any excipients in the formulation should avoid it. It is not intended for acute asthma attacks, and individuals with severe liver impairment should use it only under close medical supervision.
