Particle size of beclomethasone dipropionate produced by two nebulisers and two spacing devices.
An impactor method was used to assess the amount of beclomethasone dipropionate in particles less than 5 microns produced by two nebulisers (Pari Inhalierboy, Medix Traveller compressor with cirrhus nebuliser chamber) and two spacer devices (Volumatic and Nebuhaler). After nebulisation of 3 ml (150 micrograms) beclomethasone dipropionate the amount of drug in particles less than 5 microns was 1...
متن کاملRadiolabelling of Beclomethasone Dipropionate
Little is known about delivery of aerosolised steroids to neonatal patients undergoing assisted positive pressure ventilation and after extubation. A rabbit model has been established to investigate factors influencing drug delivery. Beclomethasone dipropionate, in a metered dose inhaler, was radiolabelied with technetium 99m. The mass median aerodynamic diameter of the aerosol was 3-3 (2.0) pm...
متن کاملNebulised beclomethasone dipropionate suspension.
We compared nebulised beclomethasone dipropionate suspension against placebo in 16 children with moderately severe asthma in double blind crossover fashion. Three children withdrew due to deterioration while on placebo. Of the remaining 13, eight were better on beclomethasone and five on placebo. These trends in favour of nebulised beclomethasone were not significant and do not suggest that the...
