The aim of this study was to compare the efficacy of 100 micrograms of salbutamol inhaled from a new metered-dose powder inhaler (MDPI, Leiras Taifun, Finland) with that of a same dose of salbutamol inhaled from a conventional pressurized metered-dose inhaler with a large volume spacer (pMDI + S) in protecting against methacholine (Mch) induced bronchoconstriction. This was a 3 day, randomized, cross-over, partly blinded, placebo-controlled multicentre study where the pMDI + S was used as an open control. Twenty-six asthmatic outpatients with a baseline FEV1 > or = 60% of predicted and with bronchial hyperreactivity (PD20 FEV1 < or = 890 micrograms of Mch) were studied. On each study day the patients underwent an Mch provocation 30 min after inhaling placebo from the MDPI or a dose of 100 micrograms of salbutamol from the MDPI and from the pMDI + S. PD20 FEV1 and dose-response slope [DRS; maximal change in FEV1 (%)/dose of Mch (mumol)] were used to evaluate efficacy. The median values of PD20 FEV1 were 250, 622 and 1737 micrograms after placebo MDPI, salbutamol pMDI + S and salbutamol MDPI, respectively. The corresponding DRS values were -11.0%, -4.5% and -2.0% mumol-1. With both parameters, all differences were statistically significant (P < 0.05). In conclusion, 100 micrograms of salbutamol inhaled from Leiras Taifun MDPI offers better protection against Mch-induced bronchoconstriction than 100 micrograms of salbutamol from a pMDI connected to a large volume spacer device.
