Viznil, Levocetirizine/ Montelukast

Montelukast is known as a leukotriene receptor antagonist. Montelukast is prescribed to help prevent asthma attacks or exercise-induced bronchoconstriction.

Montelukast 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 Montelukast helps in the treatment of these symptoms.

Levocetirizine is used in the treatment for allergic disorders and its symptoms.

Levocetirizine　is used known as a non-drowsy antihistamine, it works by blocking histamine receptors and increasing the breakdown of mucus.Levocetirizine works by selectively inhibiting the H1 histamine receptors therefore preventing histamine from acting on its receptors. Levocetirizine helps to alleviate the symptoms caused by hay fever or other allergies (such as a runny nose and watery eyes). Levocetirizine works by reducing the viscosity (thickness) of mucus, allowing for more of it to be removed from the body.
