Determination of Passive Dry Powder Inhaler Aerodynamic Particle Size Distribution by Multi-Stage Cascade Impactor: International Pharmaceutical Aerosol Consortium on Regulation & Science (IPAC-RS) Recommendations to Support Both Product Quality Control and Clinical Programs.
The multi-stage cascade impactor (CI) is the mainstay technique for the dedication of the aerodynamic particle measurement distribution (APSD) of aerosols emitted from orally inhaled merchandise (OIPs). CIs are designed to function at a continuing move charge all through the measurement course of. Nonetheless, it’s essential to mimic an inhalation maneuver to disperse the powder into an aerosol when testing passive dry powder inhalers (DPIs), […]
