The structural formula is: Montelukast sodium is a hygroscopic, optically active, white to off-white powder. Montelukast sodium is freely soluble in ethanol, methanol, and water and practically insoluble in acetonitrile. The film coating consists of: Both chewable tablets contain the following inactive ingredients: The oral granule formulation contains the following inactive ingredients: These eicosanoids bind to cysteinyl leukotriene CysLT receptors.
The CysLT type-1 CysLT1 receptor is found in the human airway including airway smooth muscle cells and airway macrophages and on other pro-inflammatory cells including eosinophils and certain myeloid stem cells. CysLTs have been correlated with the pathophysiology of asthma and allergic rhinitis. In asthma, leukotriene-mediated effects include airway edema, smooth muscle contraction, and altered cellular activity associated with the inflammatory process.
In allergic rhinitis, CysLTs are released from the nasal mucosa after allergen exposure during both early- and late-phase reactions and are associated with symptoms of allergic rhinitis.
Intranasal challenge with CysLTs has been shown to increase nasal airway resistance and symptoms of nasal obstruction. The clinical relevance of intranasal challenge studies is unknown. Pharmacokinetics Absorption Montelukast is rapidly absorbed following oral administration. After administration of the mg film-coated tablet to fasted adults, the mean peak montelukast plasma concentration Cmax is achieved in 3 to 4 hours Tmax. The oral bioavailability and Cmax are not influenced by a standard meal in the morning.
