HFA versions of pirbuterol
or triamcinolone are in development.
Beta-2-agonist inhalers, including albuterol, pirbuterol
, and terbutaline, taken 15 minutes before exercise can reduce or eliminate symptoms in up to 90% of patients for up to four to six hours.

Another class of drugs, beta agonists, such as albuterol, bitolterol, metaproterenol, pirbuterol
, and terbutaline, are used either when the symptoms occur or just before an activity that may cause symptoms.
Metered-dose inhaler Albuterol (Ventolin, Proventil) Epinephrine (Medihaler-Epi, Primatene Mist) Isoethadne (Bronchometer) Isoproterenol (Isuprel Medihaler) Isoproterenol and phenylephrine (Duo-Medihaler) Metaproterenol (Metaprel, Alupent) Pirbuterol
(Maxair) Salmeterol (Serevent) Terbutaline (Breathair)
Short-acting agents include albuterol, levalbuterol, and pirbuterol
, although these agents at one time were considered longer acting in comparison with the ultrashort-acting catecholamines such as isoetharine.
Other short- acting beta agonists used for asthma include levalbuterol (Xopenex HFA) and pirbuterol
The newer aerosol [beta]-adrenergic drugs (albuterol, terbutaline, pirbuterol
, bitolterol) are [[beta].
The more recent generation of beta-2 agonists, including albuterol, levalbuterol, bitolterol and pirbuterol
, have minimum untoward cardiovascular effects, making them ideal for managing all forms of asthma.
In support of its decision, FDA noted that it received a large number of comments from physicians and patients addressing the public health benefits of pirbuterol
- the active ingredient in Maxair Autohaler.
