Generic Singulair (Montelukast) is a leukotriene inhibitor. Leukotrienes are substances in the body that are associated with the inflammation and constriction of airway muscles and the accumulation of fluid in the lungs, all of which occur during an asthma attack.

This medicine is used for the prevention and long-term treatment of asthma. It reduces the swelling and inflammation that tend to close up the airways, and relaxes the walls of the bronchial tubes, expanding the airways and permitting more air to pass through.
Singulair is also used to relieve the stuffy, runny nose and sneezing caused by seasonal allergies. It is also used to treat allergy symptoms. Singulair works by blocking substances in the body called leukotrienes. Blocking leukotrienes improves asthma and seasonal or perennial allergic rhinitis symptoms. It may also be used to treat other conditions as determined by your doctor.

Active Ingredients: montelukast sodium.
Other Ingredients: microcrystalline cellulose, lactose monohydrate, croscarmellose sodium, hydroxypropyl cellulose, and magnesium stearate.
Class and Mechanism: Montelukast is an oral leukotriene receptor antagonist (LTRA) for the maintenance treatment of asthma and to relieve symptoms of seasonal allergies. It is not useful for the treatment of acute asthma attacks, so patients should also be supplied with rescue medication, such as an albuterol inhaler. Montelukast blocks the action of leukotriene D4 on the cysteinyl leukotriene receptor CysLT1, thus inhibiting bronchoconstriction.
