What is Singulair?
Singulair is an oral prescription drug used for chronic treatment and prophylaxis of asthma. It is also used as acute prevention for exercise-induced bronchoconstriction (EIB), and it is prescribed to relieve symptoms of allergic rhinitis, seasonal allergic rhinitis, and perennial allergic rhinitis.
This is available in Singulair 10 mg tablets.
Singulair Mechanism of Action
Singulair primarily blocks the action of leukotriene D4 in the lungs. It binds selectively and with high affinity to cystic leukotrienes type 1 receptor, which leads to the inhibition of actions of cysLTs that facilitates allergic rhinitis and asthma. This action leads to the decrease of inflammation in the lungs and relaxation of smooth muscle in the airway.
