Introduction
Salbutamol is used in bronchodilator response testing (BDRT), which is an important diagnostic tool in bronchial obstructive diseases. Most available studies compare the bronchodilator response of salbutamol administered with a pressurized metered-dose inhaler and salbutamol in a nebulization solution.

Aim
The spirometric evaluation of the bronchodilator response of two methods of salbutamol nebulization in asthmatic children.

Material and methods
A randomized, open, comparative study was conducted in which 132 children with partially controlled asthma and current bronchial obstruction determined by spirometry were enrolled. BDRT was conducted using salbutamol solution administered with either a continuous jet nebulizer (CON) or a breath-actuated jet nebulizer (BAN). The BAN group received half the dose of the drug compared to the CON group, i.e. 2.5 mg. Changes in FEV1 and FEF25–75 after drug administration were calculated in relation to the baseline values.

Results
The change in FEV1 after salbutamol administration was 16.9 ±9.7% in the BAN group and was statistically significantly higher than in the CON group (12.6 ±8.8%) (p = 0.026). The change in FEF25-75 was 37.7 ±23.2% in the BAN group and 32.7 ±25.5% in the CON group (p = 0.061). There were no statistically significant differences in the frequency of adverse events between the compared groups.

Conclusions
Salbutamol inhaled from BAN results in a better bronchodilator response than twice the nominal dose of this drug inhaled from CON, which is due to the absence of drug loss during the expiratory phase and therefore greater pulmonary deposition.
