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 symp...Continue Reading

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.
