[Effect of oral beta2-stimulant on pulmonary function in asthma patients treated with multiple medications].

This study was designed to evaluate the effect of discontinuing oral beta2-stimulant in patients with asthma who were being treated with multiple medications. Thirty-two asthmatics controlled under multiple medications who had a stable PEF were entered. Patient symptoms, PEF, FEV10, V75,V50, and V25 were evaluated before and after discontinuing beta2-stimulant.
