Pharmacology Montelukast is a selective and orally active leukotriene receptor antagonist that inhibits the cysteinyl leukotriene receptor (CysLT1). The cysteinyl leukotrienes (LTC4, LTD4, LTE4) are products of arachidonic acid metabolism and are released from various cells, including mast cells and eosinophils.
Xyflo has been administered with other therapies routinely used in the prophylaxis and chronic treatment of asthma with no apparent increase in adverse reactions.
Montelukast is contraindicated in patients who are hypersensitive to any component of this product.
Common: Diarrhoea, fever, gastrointestinal discomfort, headache, nausea, vomiting, skin reactions, upper respiratory tract infection.
Montelukast crosses the placenta following oral dosing in rats and rabbits. There are, however, no adequate and well-controlled studies in pregnant women.
Xyflo is not indicated for use in the reversal of bronchospasm in acute asthma attacks, including status asthmaticus. Patients should be advised to have appropriate rescue medication available.
There were no adverse experiences in the majority of overdosage reports. The most frequently occurring adverse experiences were consistent with the safety profile of Xyflo and included abdominal pain, somnolence, thirst, headache, vomiting and psychomotor hyperactivity.
