This drug occupies receptor sites, which prevents leukotrienes from producing their unwanted bronchoconstrictor effects, airway edema and inflammation.
Although SINGULAIR is effective in improving airway function in asthmatics with documented aspirin sensitivity, it has not been shown to truncate bronchoconstrictor response to aspirin and other non-steroidal anti-inflammatory drugs in aspirin-sensitive asthmatic patients (see CLINICAL PHARMACOLOGY, Clinical Studies).

Current therapies for moderate to severe asthma require multi-drug regimens to treat both the inflammatory and the bronchoconstrictor components of the disease.
The extract contained primarily brevetoxins 2 and 3 but also contained brevenal, a newly identified compound in K brevis having pharmacologic activity antagonistic to brevetoxin-induced neurotoxicity and bronchoconstrictor activities (Bourdelais et al.
1]-mediated pathway contributing to the bronchoconstrictor response in vivo (Abraham et al.
These vagal fibers, which mediate neurogenic bronchonconstriction and inflammation, as well as cough, have been shown to be activated by extracellular ATP in animal models in vivo, and aerosolized ATP is a potent bronchoconstrictor and cough inducer in human subjects, in particular in patients with chronic obstructive airway diseases.
6) Leukotrienes are also potent bronchoconstrictors and contribute to the NSAID-induced "aspirin asthma" in susceptible patients.
That was the first approval for a leukotriene inhibitor, a class of drugs that blocks the effect of leukotrienes, which are potent, naturally occurring bronchoconstrictors.
Bronchial Thermoplasty has been shown to reduce the narrowing of airway passages in response to bronchoconstrictors, and may potentially improve asthma symptoms in patients with this condition.
Human asthma is characterized and its severity is diagnosed by heightened airway reactivity to varying concentrations of nonspecific bronchoconstrictors or spasmogens such as methacholine.
