    Abstract:
    Hydrofluoroalkane-134a beclomethasone dipropionate extrafine aerosol breath-actuated inhaler (Qvar Autohaler; BDP-AH) provides an alternative to chlorofluorocarbon metered dose inhalers or dry powder inhalers (DPIs). The aim of this six-week, open-label study was to determine whether BDP-AH demonstrates equivalent asthma control to twice the dose of budesonide (BUD)-DPI (Pulmicort Turbuhaler). Adults with symptomatic asthma inadequately controlled on BUD-DPI 400 micrograms/day and beta-agonist were enrolled. Patients (n = 193) were randomised to receive 400 micrograms/day BDP-AH (n = 98) (two puffs of 100 micrograms/actuation inhaler twice daily) or 800 micrograms/day BUD-DPI (n = 95) (two puffs of 200 micrograms/actuation inhaler twice daily). Both groups showed a statistically significant change from baseline in morning (a.m.) peak expiratory flow (PEF) at weeks 5-6 (p < 0.01), indicating study treatment improved a.m. PEF over prestudy 400 micrograms/day BUD. Changes from baseline in a.m. PEF at weeks 5-6 were 15.9 l/min for BDP-AH and 14.2 l/min for BUD-DPI; the groups were statistically equivalent (90% CI -7.02-10.44; p < -0.001 [equivalence = within +/- 25 l/min]). Other efficacy assessments (evening PEF, FEV1, asthma symptoms, beta-agonist use) confirmed the treatments were clinically equivalent. Thirty-nine (40%) patients on BDP-AH and 35 (37%) on BUD-DPI experienced at least one adverse event (p = 0.767). Four (4%) patients on BDP-AH and 3 (3%) on BUD-DPI reported increased asthma symptoms. BDP-AH at half the daily dose provided equivalent asthma control to BUD-DPI; both treatments were well tolerated.
