Mechanism of action

Salbutamol binds to and activates beta-2 adrenergic receptors on airway smooth muscle cells, triggering a cascade that increases intracellular cAMP levels. This leads to smooth muscle relaxation and rapid bronchodilation, relieving airway obstruction. It is a short-acting bronchodilator used for acute relief of bronchoconstriction in asthma and COPD.
