Adrenaline, also known as epinephrine, is a hormone and medication involved in regulating visceral functions, such as heart rate, blood pressure, and breathing. It appears as a white microcrystalline granule. Adrenaline is normally produced by the adrenal glands and by a small number of neurons in the medulla oblongata. As a medication, epinephrine is used primarily for the emergency treatment of severe allergic reactions (anaphylaxis), asthma attacks, and cardiac arrest. It also helps prolong the effects of local anesthetics. Epinephrine works by stimulating alpha and beta-adrenergic receptors, leading to vasoconstriction, bronchodilation, and increased heart rate, which help counteract life-threatening symptoms.

During the production and storage of epinephrine, impurities can develop, which need to be closely monitored to ensure the drug’s safety and efficacy. Regulatory agencies like the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) set strict limits on acceptable impurity levels.
Epinephrine’s primary function is to prepare the body for “fight or flight” by increasing heart rate, opening airways, and constricting blood vessels. It is critical for responding to emergencies such as severe allergic reactions, asthma attacks, and cardiac arrest.
Epinephrine acts as a vasoconstrictor, meaning it narrows blood vessels, increasing blood pressure. However, it also acts as a vasodilator in certain areas, such as the lungs, where it helps to open airways and improve breathing.
Epinephrine is used in emergencies because it rapidly acts on multiple body systems, counteracting the symptoms of severe allergic reactions (anaphylaxis), asthma, and cardiac arrest. It helps to restore normal breathing, increase heart function, and reverse the dangerous drop in blood pressure that can occur during anaphylactic shock.
Epinephrine is a stimulant. It activates the body’s sympathetic nervous system, increasing heart rate, improving blood flow, and stimulating the “fight or flight” response, which helps the body respond to stressful situations.
