Abstract: Background: Pressurized metered dose inhalers (pMDIs) currently contain propellants with relatively high global warming potential (GWP), such as hydrofluoroalkane-134a (HFA-134a). Hyrofluoroolefin-1234ze (HFO-1234ze) is a near-zero GWP propellant in development for use in future pMDIs. Methods:… read more here.
