Indications & Clinical Uses

Montelukast sodium is a leukotriene receptor antagonist used in respiratory and allergic conditions.

  • Asthma: provides maintenance therapy to reduce frequency and severity of symptoms.
  • Allergic rhinitis: relieves nasal congestion, sneezing and itching.
  • Exercise‑induced bronchoconstriction: prevents bronchospasm triggered by physical activity.

How It Works

  • Montelukast sodium 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 sodium may cause a range of adverse reactions.

Common Side Effects

  • Headache: mild to moderate pain often transient.
  • Abdominal pain: discomfort or cramping in the stomach area.
  • Cough: occasional dry cough.
  • Nausea: feeling of sickness or urge to vomit.
  • Dizziness: light‑headed sensation.
  • Fatigue: unusual tiredness.

Serious or Rare Side Effects

  • Allergic reactions: rash, angioedema, or hives.
  • Mood changes: depression, anxiety, or suicidal thoughts.
  • Hepatic enzyme elevation: abnormal liver function tests.
  • Stevens‑Johnson syndrome: severe skin reaction (very rare).
  • Bronchospasm worsening: paradoxical increase in airway constriction.

Precautions & Warnings

Montelukast sodium requires careful consideration in certain patient groups and conditions.

  • Pregnancy: Category B – use only if benefit outweighs potential risk.
  • Breastfeeding: monitor infant for possible effects.
  • Renal impairment: dose may need adjustment in severe cases.
  • Hepatic impairment: use with caution; monitor liver function.
  • Drug interactions: review concomitant medications for potential interactions.
  • Store at ambient temperature: keep in original packaging, protect from moisture and direct sunlight.

Avoid Interactions

Montelukast sodium can interact with several medicines, affecting its efficacy or safety.

Major Interactions (Avoid)

  • Ritonavir: may increase montelukast plasma concentrations.
  • Phenobarbital: may reduce montelukast effectiveness.

Moderate Interactions (Monitor Closely)

  • Fluconazole: may raise montelukast levels.
  • Carbamazepine: may lower montelukast exposure.
  • Warfarin: monitor INR as changes in metabolism are possible.

Frequently Asked Questions

Montelukast Pinewood Laboratories contains montelukast sodium, which is prescribed for maintenance treatment of asthma, relief of allergic rhinitis symptoms, and prevention of exercise‑induced bronchoconstriction in both adults and children.

Montelukast sodium blocks the CysLT1 receptor, preventing leukotriene D4 from causing bronchoconstriction and airway inflammation. This action helps keep the airways open and reduces allergic inflammation.

The specific dose and dosing schedule are determined by the prescribing healthcare professional based on the patient’s age, condition severity, and clinical response. Patients should follow the prescriber’s instructions exactly.

Montelukast is classified as Pregnancy Category B, indicating no evidence of risk in animal studies but limited human data. It may be used during pregnancy if the potential benefit justifies the risk. While it passes into breast milk, many clinicians consider it compatible with breastfeeding, but a healthcare provider should evaluate each case.

To place an order, 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 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‑exacerbated respiratory disease or those who prefer a once‑daily tablet, but it may be less potent for acute symptom relief compared with inhaled bronchodilators.

Store the product at ambient temperature, preferably below 25 °C. Keep it in the original container, protect it from moisture and direct sunlight, and ensure the packaging remains sealed until use.

Montelukast Pinewood Laboratories is taken orally, usually as a tablet, once daily in the evening. It should be swallowed whole with water and not chewed or crushed unless otherwise directed by a healthcare professional.

Serious but rare risks include severe allergic reactions such as rash, angioedema, or Stevens‑Johnson syndrome, as well as neuropsychiatric events like depression, anxiety, or suicidal thoughts. Patients should seek immediate medical attention if any of these symptoms occur.

Montelukast is contraindicated in individuals with known hypersensitivity to montelukast sodium or any of the tablet’s excipients. Patients with a history of severe allergic reactions to leukotriene modifiers should avoid it, and it should be used with caution in those with liver disease.
