Salbutamol-d9 is intended for use as an internal standard for the quantification of salbutamol (Item Nos. 21003 | 23991) by GC- or LC-MS. Salbutamol is an agonist of the ?2-adrenergic receptor (?2-AR; Kd = 759 nM in a radioligand binding assay using CHO cells expressing the human receptor).{25151} It is selective for ?2-ARs over ?1- and ?3-ARs (Kds = 46.8 and 21.9 µM, respectively). Salbutamol (25-50 ?g/kg, i.v.) reduces acetylcholine-induced bronchospasm in anesthetized guinea pigs.{40769} It also reduces response of bronchial muscle to efferent vagal stimulation in anesthetized cats and dogs when administered at doses ranging from 1 to 2.5 and 10 to 20 µg/kg, respectively. Nebulized salbutamol reduces transpulmonary pressure in recurrent airway obstruction-affected horses (EC50 = 39.7 µg).{40770} Formulations containing salbutamol have been used in the treatment of asthma and chronic obstructive pulmonary disease (COPD).
