Montelucaste Alter (Montelukast)

Montelukast, the active ingredient in Montelucaste Alter, is a leukotriene receptor antagonist presented as a tablet for oral use. It is used to prevent asthma symptoms, manage exercise‑induced bronchoconstriction, and relieve allergic rhinitis in adults and children.

GNH USA supplies Montelucaste Alter as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Montelukast acts on the leukotriene pathway to control respiratory and allergic conditions.

- Asthma prophylaxis: reduces the frequency and severity of asthma attacks when used regularly. - Exercise‑induced bronchoconstriction: prevents airway narrowing triggered by physical activity. - Allergic rhinitis: alleviates nasal congestion, sneezing and itching caused by seasonal allergies.

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

Common Side Effects: - Headache: mild to moderate pain often reported. - Abdominal pain: discomfort or cramping in the stomach area. - Cough: occasional dry cough. - Fever: low‑grade temperature elevation. - Sore throat: irritation or pain in the throat. - Dizziness: feeling light‑headed or unsteady.

Serious or Rare Side Effects: - Allergic reactions: rash, angioedema, or anaphylaxis. - Neuropsychiatric events: agitation, depression, or suicidal thoughts. - Hepatic injury: elevated liver enzymes or hepatitis. - Blood disorders: neutropenia or eosinophilia. - Stevens‑Johnson syndrome: severe skin blistering. - Severe asthma exacerbation: paradoxical worsening of symptoms.

Before prescribing Montelucaste Alter, clinicians should consider several safety aspects.

- Assess asthma control: ensure baseline therapy is optimized. - Monitor neuropsychiatric symptoms: watch for mood changes or suicidal ideation. - Use with caution in hepatic impairment: dose adjustment may be required. - Avoid in known hypersensitivity: discontinue if allergic reaction occurs. - Review concomitant medications: consider potential drug interactions. - Store at room temperature: keep in the original pack, protect from moisture and direct sunlight.

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

Major Interactions (Avoid): - Strong CYP3A4 inhibitors (e.g., ketoconazole, ritonavir): may raise montelukast plasma levels. - Concurrent leukotriene modifiers (e.g., zafirlukast, zileuton): increase risk of adverse effects. - Phenobarbital: may markedly decrease montelukast exposure.

Moderate Interactions (Monitor Closely): - CYP2C9 inhibitors (e.g., fluconazole): may modestly increase exposure. - Warfarin: monitor INR as montelukast can affect anticoagulation. - Antidepressants: observe for enhanced neuropsychiatric symptoms.
