Nebulized Beclomethasone Dipropionate Improves Respiratory Lung Function in Preschool Children With Recurrent Wheezing

This is a single-centre, open label study, aiming to evaluate the efficacy of beclomethasone dipropionate applied for 12 weeks with a dose of 400 µg twice a day (total dose 800 µg nebulized), on airway resistance and reactances (measured with Rint and FOT techniques) in children with recurrent wheezing, aged 2-5 years. In addition, clinic score as frequency of symptoms and exacerbations, will be assessed.
