A comprehensive analytical and PDA and imaging survey of the aerosol plumes produced by a pressurised metered dose inhaler, pMDI using placebo and active formulations based on the HFA227 propellant is in progress. The work described here concentrates on, what the authors believe, are the first set of PDA measurements in the near-orifice region of a pharmaceutical pMDI. The axial and radial velocity components and the arithmetic and Sauter mean diameter profiles are presented and discussed in a… CONTINUE READING
