Mechanism of Action:
Selective short-acting beta-2 adrenoceptor agonist i.e. has minimal effect on beta-1 adrenoceptors and is inactive at alpha-adrenoceptors. Actions of beta-2 adrenoceptor (a seven-transmembrane G-protein-coupled receptor) include: bronchodilation, vasodilation, smooth muscle relaxation. Its actions are achieved through activation of adenylate cyclase, which causes the formation of cylic AMP (second messenger) from ATP.
