SALBUMOL (Salbutamol)
Salbutamol is a selective β-2 adrenoceptor agonist. It has very little or no action on the β-1 receptors of the heart. At therapeutic doses, salbutamol acts on the β-2 receptors of the bronchial muscle, the end effect being dilation of the bronchial airways through relaxation of bronchial smooth muscle and reduction of airway resistance.
