摘要：In a method of producing particles suitable for use as carrier particles in drypowder inhalers, particles () of a size suitable for use as carrier particles in dry powderinhalers are treated so as to dislodge small grains from the surface of the particles,
without substantially changing the size of the particles during the treatment. Thetreatment gives improved efficiency of redispersion of active particles from the surfacesof carrier particles.
