The classes and their drugs

Short-acting beta-2 agonistsActivating airway beta-2 receptors to relax bronchial muscle within minutes
SalbutamolTerbutaline
Long-acting beta-2 agonistsActivating airway beta-2 receptors for long-lasting bronchodilation
SalmeterolFormoterol
Inhaled antimuscarinicsBlocking airway muscarinic receptors so vagal acetylcholine cannot narrow them
IpratropiumTiotropium
Inhaled corticosteroidsActivating glucocorticoid receptors to switch off airway inflammation
BeclometasoneBudesonideFluticasone
Leukotriene receptor antagonistsBlocking CysLT1 receptors so leukotrienes cannot narrow the airways
Montelukast
MethylxanthinesInhibiting phosphodiesterases and blocking adenosine receptors in the airways
Theophylline
First-generation antihistaminesBlocking H1 receptors in body and brain, so they also sedate
ChlorphenaminePromethazine
