Uses and Benefits of Montair FX Tablet:

Montair FX is used for the treat and prevention of various conditions and diseases such as –

  • Allergic rhinitis – Allergic rhinitis or hay fever is an inflammation of the nose. The condition occurs when the immune system overreacts to the allergens present in the air. Symptoms associated with the condition include sneezing, itchy and watery eyes, red and stuffy nose and swelling around the eyes. Allergic rhinitis is triggered by environmental allergens such as pet hair, dust, pollen or mould.
  • Asthma – It is an inflammatory disease of the airways of the lungs. The condition is characterized by blockage of the airways, difficulty in breathing, wheezing, chest tightness and coughing. These symptoms may occur a few times in a day or a few times per week. Also, the condition may become worse at night.
  • Bronchospasm – It is a condition characterized by tightening in the muscles that line the airways of the lungs. This tightening leads to narrowing of the bronchi (airways in the lungs) and makes it difficult for the air to come in or go out of the lungs. This limits the amount of oxygen that enters the blood and amount of carbon dioxide that leaves the blood. Some of the symptoms associated with the condition are wheezing, coughing and fatigue.

How does Montair FX Tablet work?

Montair FX Tablet works by blocking the activity of chemical messengers that lead to inflammation.

Individual mechanism –

  • Montelukast – Montelukast works by blocking the action of leukotriene D4 present on the cysteinyl leukotriene receptor CysLT1 in the airways of the lungs. This action of the medicine reduces the activity of leukotriene which is responsible for the tightening of the airway muscles and for the production of excess mucus in the lungs.
  • Fexofenadine – Just like other H1-blockers, Fexofenadine also competes with free histamine for binding to the H1-receptors present in the bronchial smooth muscle, GI tract and large blood vessels. The action of the medicine blocks the activity of endogenous histamine, which leads to temporary relief from the negative symptoms such as nasal congestion and watery eyes brought on by the action of histamines.
