Montelucaste Bluefish (Montelukast)

Montelukast, the active ingredient in Montelucaste Bluefish, is a leukotriene receptor antagonist presented as an oral dosage form for oral use. It is indicated for the management of asthma, exercise‑induced bronchoconstriction, allergic rhinitis and chronic urticaria in adults and children as prescribed by a healthcare professional.

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

Montelukast acts on leukotriene pathways to control inflammatory airway conditions. - Asthma: reduces the frequency of wheezing episodes and improves lung function in persistent asthma. - Exercise‑induced bronchoconstriction: prevents airway narrowing triggered by physical activity. - Allergic rhinitis: alleviates nasal congestion, sneezing and itching caused by seasonal allergens. - Chronic urticaria: decreases the occurrence of hives and associated itching in patients with refractory chronic urticaria.

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

Common Side Effects: - Headache: mild to moderate intensity. - Upper respiratory tract infection: transient symptoms. - Dyspepsia: occasional stomach discomfort. - Cough: non‑productive. - Fatigue: feeling of tiredness. - Nasopharyngitis: mild nasal inflammation.

Serious or Rare Side Effects: - Neuropsychiatric events: agitation, anxiety, or mood changes. - Allergic reactions: rash, angioedema, or urticaria. - Hepatotoxicity: abnormal liver enzymes. - Stevens‑Johnson syndrome: severe skin blistering. - Anaphylaxis: rapid onset of systemic allergic response.

Montelukast should be used with consideration of the following precautions. - Pregnancy: safety not established; discuss risks with a healthcare provider. - Breastfeeding: assess benefit‑risk ratio before use. - Hepatic impairment: monitor liver function in patients with liver disease. - Concomitant asthma therapy: do not discontinue inhaled corticosteroids without medical advice. - Age restrictions: use in children only as directed by a prescriber. - Store at ambient temperature: keep below 25 °C, retain in original packaging, and protect from moisture.

Montelukast may interact with several medicines; monitoring is advised.

Major Interactions (Avoid): - Phenobarbital: may reduce montelukast plasma concentrations. - Rifampin: induces metabolism, potentially decreasing efficacy.

Moderate Interactions (Monitor Closely): - Antidepressants (e.g., fluoxetine): may increase risk of neuropsychiatric effects. - Antihistamines: additive sedation is uncommon but possible. - CYP3A4 inhibitors (e.g., ketoconazole): may modestly raise montelukast levels. - Warfarin: monitor INR as theoretical interaction exists. - Oral contraceptives: no significant interaction, but standard monitoring applies.
