Singulair is known as a leukotriene receptor antagonist. Singulair is prescribed to help prevent asthma attacks or exercise-induced bronchoconstriction.
How it Works
Singulair works to control the symptoms of asthma by blocking the effects leukotrienes. Leukotrienes are produced by the body when asthma symptoms flare up, this may be caused without or with reason being exercise or pollen exposure. Such instances cause body to produce chemical substances called leukotrienes, which cause the inflammation in the smaller airways of the lungs.The inflammation irritates the muscles around the airways and causes them to constrict, this causes airways to narrow which makes it more difficult for air to get in and out of the lungs. This causes the typical symptoms of wheeze, chest tightness and shortness of breath. The inflammation also causes the lining of airways to make extra mucus which causes coughing. Thus Singulair helps in the treatment of these symptoms.
