Not as widely used as albuterol inhalers, pirbuterol acetate is very similar in effect. Pirbuterol acetate is used primarily as a rescue inhaler, but is also used prophylactically, often to prevent exercise-induced asthma.

The Maxair™Autohaler™ works like a demand valve and automatically discharges the medication canister as the patient inhales which mixes the dose of medication with air quite well. It is also useful for patients who are unable to coordinate pressing the medication canister in time with their inhalation. There is one potentially serious drawback to the Maxair™Autohaler™: During a severe asthma attack, the patient may not be able to move enough air to activate the inhaler.
