Ambroxol+Levocetirizine+Montelukast is used in asthma prevention.

This is a combination of three medicines: Ambroxol, levocetirizine and montelukast which decrease the frequency of asthma attacks and relieve the symptoms of allergies associated with mucus (phlegm). Ambroxol is a mucolytic which thins and loosens mucus (phlegm), making it easier to cough out. Levocetirizine is an antiallergic which relieves allergy symptoms like runny nose, watery eyes and sneezing. Montelukast is a leukotriene antagonist. It works by blocking the action of leukotriene, a chemical messenger. This reduces inflammation in the airways and nose and improves your symptoms.
