A powerful environmentally-friendly inhaler for conditions like asthma and chronic obstructive pulmonary disease (COPD) could be available on the market in five years’ time after healthcare group Chiesi announced plans for its development.

It has secured a commercial agreement for the supply of HFA 152a (1,1-difluoroethane) – a sustainable medical propellant – with manufacturer Koura.

Chiesi claims this propellant will decrease the carbon footprint of a pMDI to a similar level as a dry powder inhaler (DPI).
