摘要: An inhaler (1) for producing an inhalable aerosol of powdered medicament is disclosed. The inhaler (1) comprises an aerosolising device having a cyclone chamber (45) of substantially circular cross-section, inlet (24) and outlet (25) ports at opposite ends of the chamber (45) for the flow of drug laden air through the chamber (45) between said ports (24, 25) and, a bypass air inlet (46) for the flow of clean air into the chamber (45). The bypass air inlets (46) are configured so that air entering the chamber (45) through said inlet (46) forms a cyclone in the chamber (45) that interacts with the drug laden air flowing between the inlet (24) and outlet (25) ports. The inhaler (1) may have a tapered drug laden air flow conduit (70) to accelerate the flow prior to entry into the chamber (45) and/or an impaction element (81, 84, 92, 105) to deagglomerate drug particles.
