Pharmaceutical assessment of low global warming potential alternatives to HFA-134a in a budesonide, glycopyrrolate, and formoterol fumarate pressurized metered dose inhaler

2026-05-16

Abstract excerpt

Manufacturers are adopting propellants for use in pressurized metered-dose inhalers (pMDIs) that have lower global warming potentials (GWPs) than the propellants traditionally used in pMDIs. Hydrofluoroalkane (HFA)-134a has been used as the propellant in the pMDI used to deliver the fixed-dose triple combination of budesonide, glycopyrrolate and formoterol fumarate (BGF); following successful clinical evaluation,...
