Montelukast Teva

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

GNH USA supplies Montelukast Teva as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The product meets European Union quality standards and is manufactured under strict GMP conditions. It is available for bulk distribution to meet global demand.

Montelukast acts on the leukotriene pathway to control chronic respiratory and allergic conditions. - Asthma: reduces frequency of asthma attacks and improves lung function in patients with persistent asthma. - Allergic rhinitis: alleviates nasal congestion, sneezing and itching associated with seasonal allergies. - Exercise‑induced bronchoconstriction: prevents airway narrowing during and after physical activity.

Montelukast may cause a range of adverse reactions, which are categorized by frequency and severity. Common Side Effects: - Headache: mild to moderate headache reported. - Abdominal pain: occasional stomach discomfort. - Nausea: feeling of queasiness. - Diarrhea: loose stools. - Upper respiratory infection: mild cold‑like symptoms. Serious or Rare Side Effects: - Allergic reactions: rash, angioedema or anaphylaxis. - Mood changes: depression, suicidal thoughts or behavior. - Liver enzyme elevation: signs of hepatic dysfunction. - Blood dyscrasias: neutropenia or eosinophilia.

When prescribing Montelukast, clinicians should consider several safety precautions. - Pregnancy: safety not established; use only if potential benefit justifies risk. - Breastfeeding: assess risk; limited data available. - Hepatic impairment: monitor liver function, dose adjustment may be needed. - Neuropsychiatric effects: observe patients for mood changes or suicidal ideation. - Drug interactions: review concomitant medications for potential interactions. - Store at ambient temperature: keep below 25 °C in original packaging, protect from moisture and light.

Montelukast can interact with other medicines, affecting its efficacy or safety. Major Interactions (Avoid): - Phenobarbital, carbamazepine, phenytoin: enzyme inducers that may reduce montelukast plasma levels. - Rifampin: strong CYP3A4 inducer, may decrease therapeutic effect. Moderate Interactions (Monitor Closely): - Warfarin: may increase INR; monitor coagulation parameters. - Protease inhibitors (e.g., ritonavir): may increase montelukast exposure; observe for side effects. - Fluconazole: CYP2C9 inhibitor, may raise montelukast levels.
