Breakthrough design for asthma inhalers

摘要

Monash University has announced that a team of chemical engineers has developed a new manufacturing method for the more efficient delivery of asthma inhaler medication. The new technique was developed by Dr Meng Wai Woo and his team at Monash's Department of Chemical Engineering. Known as anti-solvent vapour precipitation, the method uses ethanol to dehydrate droplets and results in uniformly sized particles less than 1 μm in diameter. The ultrafine particles ensure that more medication reaches the lower regions of the lungs without getting caught in a persons throat.
