Four commercially available beclomethasone metered dose inhalers were analyzed for both spray content uniformity and particle size. The drug contents of primed and unprimed sprays collected at the beginning of the lifetime of the canister were not significantly different from those collected through

In a double-blind cross-over study, 12 patients with reversible airways obstruction were treated with 200 micrograms salbutamol base in aerosol or 400 micrograms of powder following methacholine-induced bronchoconstriction. Salbutamol was inhaled either from a conventional metered dose inhaler (MDI)
The purpose of this study was to evaluate the Malvern Spraytec 1 with inhalation cell attachment as a means of analyzing the particle size distribution of aerosols from pressurized metered dose inhalers (pMDIs). The aerosol particle size distribution of various commercially available, placebo, and e
