WebJun 23, 2024 · Beta-2 adrenergic agonists are a drug class used as a mainstay treatment for respiratory diseases such as bronchial asthma and chronic obstructive pulmonary disease (COPD). They replicate the functions of catecholamines such as epinephrine, norepinephrine, and dopamine in producing different autonomic responses within the body. WebThus, the hormones secreted by the endocrine glands enter the circulation and are carried throughout the body to act upon target cells located far away from the secreting glands. Endocrine glands secrete directly into the bloodstream, not through a duct system.
