Airsupra is a combination inhaler that contains albuterol and budesonide, approved for as-needed use in adults with asthma. It represents the first rescue inhaler to combine a short-acting beta-2 agonist (SABA) with an inhaled corticosteroid (ICS) in a single device. The albuterol component provides rapid bronchodilation by relaxing airway smooth muscle, while budesonide works to reduce airway inflammation and mucus production. This dual mechanism allows Airsupra to not only relieve acute bronchoconstriction but also address the underlying inflammatory process that contributes to asthma exacerbations.
Clinically, Airsupra is indicated for as-needed treatment or prevention of bronchoconstriction in adults with asthma, but it is not approved for COPD. The typical dosing is two inhalations as needed, with a maximum of six doses (12 inhalations) in a 24-hour period. 
The rationale for its use aligns with recent asthma guideline updates, which emphasize minimizing SABA-only use because it fails to address inflammation and may contribute to worse outcomes over time.
Common adverse effects include tremor, nervousness, tachycardia, and hypokalemia from albuterol, as well as oral thrush and hoarseness from budesonide. Patients should rinse and spit after each use to reduce the risk of oral candidiasis. 
Drug interactions can occur with non-selective beta-blockers, which may blunt albuterol’s effects. CYP3A4 also plays a role in budesonide metabolism. Systemic absorption typically isn&#8217;t too much of an issue with infrequent use.
