Summary for Patent: 6,582,678
| Title: | Carrier particles for use in dry powder inhalers |
| Abstract: | In a method of producing particles suitable for use as carrier particles in dry powder inhalers, particles (1) of a size suitable for use as carrier particles in dry powder inhalers 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. The treatment gives improved efficiency of redispersion of active particles from the surfaces of carrier particles. |
