What is the function of adrenaline

Adrenaline is generally used to increase the contractility of the heart, dilate the blood vessels of the heart, liver and muscles, and contract the blood vessels of the skin and mucous membrane. In medicine, adrenaline is used to stimulate the heart when the heart stops, or to dilate the trachea during an asthma attack. It can contract the blood vessels of skin, mucous membrane and viscera (such as kidney), and dilate the blood vessels of coronary artery and skeletal muscle.

Clinically, it is mainly used in the rescue of cardiac arrest and anaphylactic shock, and can also be used for other allergic diseases. For example, the treatment of bronchial asthma and urticaria. Combined with local anesthetics can play a beneficial role in local hemostasis and prolonging efficacy.

The product directly acts on adrenergic α and β receptors, producing strong, rapid and short-term excitation α and β effects. The excitation of cardiac β 1-receptor can enhance the contractility of myocardium, accelerate heart rate and increase oxygen consumption of myocardium. At the same time, it acts on the β 2-receptor of vascular smooth muscle to dilate the vessels and reduce the diastolic blood pressure due to the decrease of peripheral vascular resistance. Stimulation of β 2-adrenoceptor can relax bronchial smooth muscle, dilate bronchus and relieve spasm of bronchus; stimulation of α - adrenoceptor can make skin, mucosal blood vessels and visceral small blood vessels contract. Clinically, it is mainly used for cardiac arrest, bronchial asthma, anaphylactic shock, urticaria, hay fever, nasal mucosa or gingival bleeding.
