Salbutamol HFA-152a clinical trials

A Study to Compare the Relative Potency of Salbutamol Administered Via Metered Dose Inhalers (MDI) Containing Propellants HFA-152a to HFA-134a in Mild Asthmatics Aged 18 to 65 Inclusive

This study is looking at two different versions of salbutamol (a common asthma inhaler) delivered through a puffer. We want to see how well they work to prevent asthma symptoms in people with mild asthma, comparing a newer propellant (HFA-152a) with an older one (HFA-134a).
