Indications & Clinical Uses

Montelukast acts on the leukotriene pathway to control respiratory disorders.

  • Asthma: improves long‑term control and reduces the frequency of asthma attacks.
  • Exercise‑induced bronchoconstriction: prevents narrowing of airways during physical activity.
  • Allergic rhinitis: alleviates nasal congestion, sneezing and itching associated with seasonal allergies.

How It Works

  • Montelukast selectively blocks the cysteinyl leukotriene receptor CysLT1, inhibiting the action of leukotrienes D4, C4 and E4. This antagonism reduces leukotriene‑mediated bronchoconstriction, vascular permeability, and inflammatory cell recruitment, thereby decreasing airway narrowing and inflammation in the respiratory tract.

Side Effects

Montelukast may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects

  • Headache: mild to moderate pain in the head.
  • Upper respiratory infection: symptoms such as sore throat or runny nose.
  • Abdominal pain: discomfort in the stomach area.
  • Cough: persistent dry cough.
  • Dyspepsia: indigestion or upset stomach.
  • Fever: mild temperature elevation.

Serious or Rare Side Effects

  • Allergic reactions: rash, swelling, or anaphylaxis.
  • Mood changes: depression, suicidal thoughts, or agitation.
  • Hepatotoxicity: signs of liver injury such as jaundice or elevated enzymes.

Precautions & Warnings

Before prescribing Montelukast Dura, consider the following precautions to ensure safe use.

  • Assess medical history: confirm no prior hypersensitivity to montelukast or related compounds.
  • Monitor psychiatric status: watch for mood changes, depression or suicidal thoughts.
  • Evaluate liver function: consider baseline tests in patients with hepatic impairment.
  • Use in children: follow pediatric guidelines and age‑specific safety data.
  • Pregnancy and lactation: discuss potential risks with the prescriber; data are limited.
  • Store at ambient temperature: keep below 25 °C in the original packaging, protected from moisture.

Avoid Interactions

Montelukast can interact with other medicines; awareness of key interactions helps avoid reduced efficacy or increased toxicity.

Major Interactions (Avoid)

  • Phenobarbital: may decrease montelukast plasma concentrations.
  • Rifampin: induces metabolism, potentially lowering therapeutic effect.

Moderate Interactions (Monitor Closely)

  • Antidepressants (SSRIs, SNRIs): may increase risk of neuropsychiatric events.
  • CYP3A4 inhibitors (ketoconazole, erythromycin): could raise montelukast levels.
  • Warfarin: monitor INR as montelukast may affect anticoagulation.

Frequently Asked Questions

Montelukast Dura is prescribed to prevent asthma attacks, control exercise‑induced bronchoconstriction, and relieve symptoms of allergic rhinitis such as nasal congestion, sneezing and itching. It works as a maintenance therapy rather than a rescue medication for acute attacks.

Montelukast selectively blocks the cysteinyl leukotriene receptor CysLT1, preventing leukotrienes from binding. This inhibition reduces bronchoconstriction, airway edema, and inflammatory cell recruitment, leading to improved breathing and fewer allergy‑related nasal symptoms.

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

Safety data for Montelukast during pregnancy and lactation are limited. Healthcare providers should weigh the potential benefits against any possible risks and discuss them with the patient before initiating therapy.

To request Montelukast Dura, submit an enquiry on the product page at gnhindia.com with 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 other leukotriene blockers such as zafirlukast. It is generally well‑tolerated and convenient for once‑daily dosing, but efficacy may differ based on individual response and disease severity.

Store Montelukast Dura at ambient temperature, preferably below 25 °C, in its original packaging to protect it from moisture. Keep the product out of reach of children and avoid exposure to direct sunlight or extreme heat.

Montelukast Dura is taken orally, usually once daily in the evening, with or without food. The tablet should be swallowed whole with water and not crushed or chewed unless otherwise directed by a healthcare professional.

Serious adverse events include severe allergic reactions (rash, swelling, anaphylaxis), mood alterations such as depression or suicidal thoughts, and rare liver injury indicated by jaundice or abnormal liver tests. Patients should seek immediate medical attention if any of these symptoms occur.

Montelukast Dura should be avoided in individuals with known hypersensitivity to montelukast or any component of the formulation. Caution is also advised for patients with a history of severe psychiatric disorders, liver disease, or those taking medications that may interact significantly.
