Montelar (Montelukast Sodium)

Montelukast, the active ingredient in Montelar, is a leukotriene receptor antagonist presented as an oral dosage form for oral use. It treats asthma, allergic rhinitis and exercise‑induced bronchospasm in adults and children.

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

Montelar is a leukotriene receptor antagonist used to manage respiratory allergic conditions.

Asthma: improves control of chronic airway inflammation and reduces frequency of exacerbations. Allergic rhinitis: alleviates nasal congestion, sneezing and itching caused by seasonal allergens. Exercise‑induced bronchospasm: prevents airway narrowing during or after physical activity.

Montelar may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects: - Headache: mild to moderate intensity. - Upper respiratory tract infection: nasopharyngitis or common cold symptoms. - Abdominal pain: discomfort or cramping in the stomach area. - Cough: occasional dry or productive cough. - Diarrhoea: loose stools occurring intermittently. - Rash: mild skin redness or itching.

Serious or Rare Side Effects: - Mood changes: depression, anxiety, or suicidal thoughts. - Hepatic dysfunction: elevated liver enzymes or hepatitis. - Angio‑edema: swelling of lips, tongue or face. - Anaphylaxis: severe allergic reaction with respiratory distress. - Stevens‑Johnson syndrome: severe skin blistering and detachment. - Blood dyscrasias: rare cases of neutropenia or eosinophilia.

Before prescribing Montelar, clinicians should consider patient‑specific factors and monitor for potential risks.

Pregnancy: assess risk‑benefit ratio; limited data are available. Breastfeeding: weigh potential infant exposure against maternal benefit. Renal or hepatic impairment: use with caution; monitor liver function. Concomitant psychiatric disorders: observe for mood alterations. Drug interactions: review patient’s medication list for known interactions. Store at ambient temperature: keep below 25 °C, retain in original packaging, protect from moisture and direct sunlight.

Montelar can interact with several medicines; awareness of interaction severity guides clinical decisions.

Major Interactions (Avoid): - Phenobarbital: may reduce montelukast plasma concentrations. - Rifampin: induces metabolism, potentially lowering efficacy. - St. John’s wort: may decrease drug exposure through enzyme induction.

Moderate Interactions (Monitor Closely): - Antidepressants (SSRIs, SNRIs): monitor for mood changes. - Warfarin: occasional reports of altered INR; check coagulation status. - Beta‑agonists: assess for additive bronchodilator effects.
