Beta blocking agents

• Salmeterol is a long-acting beta-adrenergic receptor agonist.
• It stimulates the beta-2 receptors present in the bronchial musculature, which leads to their relaxation. They act on the enzyme adenyl cyclase which increases the concentration of cAMP. This cyclic AMP decreases the tone of the smooth muscles.
