Background: Salbutamol inhalation is the mainstay of treatment for acute
exacerbation of asthma. A number of delivery systems for asthma medication have
been developed for children, each having its own advantages and disadvantages.
This study was done to compare the bronchodilator effect of salbutamol inhalation
delivered through metered dose inhaler (MDI) with spacer and dry powder inhaler
(DPI) in children presenting with mild and moderate acute asthma.
