ABSTRACT
The study represents the investigation on pharmacodynamic lung function testing in 40 patients (21 with extrinsic asthma and 19 with intrinsic asthma). Skin prick tests on common inhalation allergens, IgE antibodies, spirometry, flow-volume curve, body plethysmography and pharmacodynamic testing with salbutamol spray were performed in each person. The greatest changes after beta 2 agonist were established by plethysmographic parameters SGaw (mean increase 117%) and Raw (mean decrease 45%), than by the expiratory flow rates from flow-volume curve: FEF25%-75% and FEF50% (mean increase 26%), than the FEV1 (+ 15%), the PEF (also + 15%), the RV (mean decrease 17%) and the FVC (mean increase 8%). The aim of this study was to represent the necessity of the complex analysis and interpretation of the results of pharmacodynamic testings because of many factors that might change the values of the tests.
