Purpose: The effect of the oral montelukast compared to the inhaled beclomethasone on the control of pediatric persistent asthma
Inclusion criteria: Children aged 6-10 years with persistent asthma symptoms. (The criterion for asthma diagnosis was based on GINA considering the history, clinical examination and respiratory function test).
Exclusion criteria: Children with lung infections, any underlying illness (simultaneous cardiac disease, antihistamine use, having any illness and taking other medications).
Population: Children with persistent asthma, referring to Amirkola Children's Hospital in 2016
Allocation of samples will do as block randomization with foursome blocks in two groups: ABBA/BAAB/BBAA/AABB/ABAB/ABBA/BAAB/BBAA/AABB/ABAB/ABBA/BAAB/BBAA/AABB/ABAB/ABBA/BAAB/BBAA/AABB/ABAB/
Also, test and its interpretation will perform by the relevant technician and master, respectively as single blind.
Sample size: Considering the admission of 82, 45% for both groups, 40 patients per group and totally 80 children.
Secondary outcomes: Quality of night sleep and absence from school.
Primary outcome: Improvement in FEV1 values
Intervention: Patients of one group will receive 100 micrograms of inhaled beclomethasone three times a day with 5 mg of montelukast tablets daily, while another group only will receive 100 micrograms of inhaled beclomethasone three times a day. Before and 3 months after treatment, the FEV1, IgE, eosinophilia, night sleep quality (sleep deprivation) and absence from school will be recorded. At the end of the treatment for two groups in the questionnaire (by one person) and also in the third month, the probable complications of montelukast (headache, diarrhea, nausea and hives) will be recorded. The FEV1 response to treatment is greater than 80%.
