- OBJECTIVE: To compare the onset of bronchodilation with a new formoterol hydrofluoroalkane (HFA) pressurized metered-dose inhaler (pMDI) with albuterol (salbutamol) HFA pMDI. PATIENTS AND METHODS: Thirty patients with stable mild or moderate asthma (23 using inhaled corticosteroids, mean FEV(1) 82% of predicted, >or=15% reversibility to terbutaline 1mg after 30 minutes) received formoterol HFA (Oxis) 2 x 4.5microg, albuterol HFA (Ventoline) Evohaler) 2 x 100microg, or placebo at three separate visits in this randomized, double-blind, double-dummy, three-way crossover study. FEV(1) was measured before and 3, 10, 20, 30 and 60 minutes after inhalation. Change in FEV(1) at 3 minutes after inhalation was the primary variable. RESULTS: Mean baseline FEV(1) was stable on all study days (range 2.92-2.94L). FEV(1) values at 3 minutes were: formoterol 3.22L (8% increase), albuterol 3.23L (9% increase) and placebo 2.99L (both p < 0.001 vs placebo). Maximum FEV(1) increased similarly with formoterol and albuterol, with no differences observed between the active treatments at any time point. Patients rated treatment effective at 3 minutes in 15 of 30, 19 of 30 and 7 of 30 cases with formoterol, albuterol and placebo, respectively. All treatments were well tolerated. CONCLUSION: In stable, mild, or moderate asthma, formoterol 9microg and albuterol 200microg, both by HFA pMDI, provided equally rapid and effective bronchodilation.
