New inhaler propellant tested in mild asthma study

NCT ID NCT06433921

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether a new propellant (HFA-152a) in salbutamol inhalers works as well as the current one (HFA-134a) for people with mild asthma. 84 adults aged 18-65 will receive single doses of the inhaler or a placebo. The main goal is to measure how well the inhaler protects against airway narrowing triggered by a substance called methacholine.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

salbutamol (albuterol) inhaler with a new propellant (HFA-152a)

What this could lead to

If successful, this could show that the new propellant works just as well as the current one, potentially leading to a more environmentally friendly inhaler option.

What could go wrong

This is an early phase 1 study with only 84 people, so results may not apply to everyone. The new propellant might not work as well or could have unexpected side effects.
