New drug for asthma, Singulair (montelukast)
You'll see a new drug for asthma, Singulair (montelukast). Merck is launching it now in the U.S....later in Canada.
Singulair is a leukotriene receptor antagonist...in the same class as Accolate (zafirlukast).
They both block leukotrienes in the lungs that cause bronchoconstriction and inflammation. This can lead to fewer asthma attacks and decreased use of other asthma meds.
