Montelukast
Montelukast Sandoz is a leukotriene receptor antagonist that inhibits the activity of substances called leukotrienes. Leukotrienes cause narrowing and swelling of the airways. By inhibiting the action of leukotrienes, Montelukast Sandoz alleviates asthma symptoms and helps control asthma.
The doctor has prescribed Montelukast Sandoz to treat asthma in the child and prevent its symptoms from occurring during the day and at night.
Montelukast Sandoz 4 mg is used to treat patients aged 2 to 5 years who have not achieved adequate asthma control with their current medications and require additional medication.
Montelukast Sandoz 4 mg may also be used instead of inhaled corticosteroids in children aged 2 to 5 years who have not recently taken oral corticosteroids and are unable to use inhaled corticosteroids.
Montelukast Sandoz 4 mg also helps prevent bronchospasm caused by physical exertion in patients aged 2 years and older.
The doctor will determine how to take Montelukast Sandoz based on the child's symptoms and the severity of the asthma.
Asthma is a chronic disease.
Asthma consists of:
difficulty breathing due to airway narrowing, which worsens or improves in response to various factors.
airway hypersensitivity, causing them to react to many factors, such as cigarette smoke, plant pollen, cold air, or physical exertion.
inflammation (inflammation) of the lining of the airways.
Asthma symptoms include: coughing, wheezing, and a feeling of pressure in the chest.
