Beskrivelse
Inclusion Criteria:
- age 4-14 years
- patients had mild to moderate persistent asthma. Patients have treated with low-dose inhaled corticosteroids (equivalent to Fluticasone propionate inhaled aerosol 250 ug/ day) combined with Leukotriene receptor antagonist (Montelulast) at least 6 months of and had no symptoms of asthma for nearly 3 months under well asthma control(Asthma Control Test (ACT) score more than or equal to 20).
- patients did not suffer from other acute or chronic diseases that may affect their growth and development
Exclusion Criteria:
- patients with severe persistent asthma or mild persistent asthma failed to be well controlled by low-dose ICS after starting treatment
- suffer from other diseases: Congenital heart disease, chronic infectious disease, protracted diarrhea, congenital airway disease, congenital vascular ring malformation, congenital immune deficiency, tracheal foreign body, bronchial lymph node tuberculosis and gastroesophageal reflux etc.
- patients with poor compliance stop medication or fail to take medication on time.

Aktiv komparator: Stop Fluticasone propionate Inhaled Aerosol Firstly
Reduced dose Fluticasone propionate Inhaled Aerosol 125 ug once a day and continuation of montelukast once a day,and then stopped Fluticasone propionate Inhaled Aerosol and continuation of montelukast once a day
|
The study consists of two stages and include three groups.
Three groups include: Reduced dose Fluticasone propionate Inhaled Aerosol 125 ug once a day and continuation of montelukast once a day,and then stopped Fluticasone propionate Inhaled Aerosol and continuation of montelukast once a day; Reduced dose Fluticasone propionate Inhaled Aerosol 125 ug once a day and continuation of montelukast once a day,and then stopped montelukast and continuation of Fluticasone propionate Inhaled Aerosol 125 ug once a day; Stopped montelukast and continuation of Fluticasone propionate Inhaled Aerosol 125 ug twice daily, and then Reduced dose Fluticasone propionate Inhaled Aerosol 125 ug once a day.
The scheme of every group is divided into two stages.
Only those whose asthma are well controlled at the end of the first phase will be allowed to proceed to the next phase.
