Are all pMDI fluticasone propionate + salmeterol products the same? Preliminary report Preliminary report
Main Article Content
Abstract
The paper presents the results of a study evaluating the basic parameters characterizing the aerosol cloud (aerodynamic diameter value which corresponding to the median of the mass particle size distribution, fine particle fraction, geometric standard deviation) generated by pressurized metered dose inhaler containing a combination of a glucocorticosteroid with a long-acting β2-mimetic. Three fluticasone propionate products available on the Polish market were compared with salmeterol (one reference and two generic). Based on the determined parameters, the inhaled aerosol deposition on particular levels of the respiratory system was determined. There were slight differences between the tested products.
