Adrenaline is used in cases of high blood pressure in cases of severe shock, as it improves blood flow and increases heart efficiency. It is widely used in cases of angioedema, which include severe reactions resulting from allergies. Adrenaline is useful in treating cases of cardiac arrest, as it is given in cases of cardiopulmonary resuscitation. Adrenaline works to increase blood flow to the heart and brain, which helps restore the normal heart rhythm.
Adrenaline is sometimes used as a treatment to relieve severe asthma attacks, as it expands the airways, making breathing easier. This medicine is used when other medications, such as corticosteroids or other bronchodilators, are not sufficient.
