This book presents work on nanocarrier systems for pulmonary drug delivery for use in the treatment of asthma. Using sucrose as a carrier, liposomes were generated or dispersed in situ from proliposomes within the medical nebulisers investigated. The Pari (air-jet) and the Omron (vibrating-mesh) nebulisers produced large mass and lipid outputs with a large lipid fraction deposited in the lower stage of a two-stage impinger. The Liberty (Ultrasonic) nebuliser failed to deliver more than 6% of the lipid employed.Multilamellar liposomes were generated from ethanol-based proliposomes. The...
