Epinephrine (Adrenaline)

Epinephrine, also known as adrenaline, is a hormone produced by the adrenal glands in response to stress or danger. It prepares the body for a rapid response—sometimes called the "fight or flight" reaction—by increasing heart rate, opening airways, and boosting blood flow to muscles. This helps you react quickly in emergency situations. Epinephrine is also used medically to treat severe allergic reactions, cardiac arrest, and asthma attacks. It acts quickly to improve breathing, increase blood pressure, and restore heart function, making it a vital emergency medication.
