Homonym: epinephrine (Adrenaline)
Epinephrine, also known as adrenaline, is a hormone produced by the adrenal glands that plays a crucial role in the body's response to stress. When faced with danger or excitement, epinephrine is released into the bloodstream, preparing the body for a "fight or flight" response. This leads to increased heart rate, improved blood flow to muscles, and heightened alertness.
In medical settings, epinephrine is often used as a treatment for severe allergic reactions, known as anaphylaxis. It can quickly reverse symptoms like swelling and difficulty breathing by relaxing the muscles in the airways and tightening blood vessels. This makes it a vital medication for those with severe allergies.
