Adrenaline (W) Sticker

Epinephrine, also commonly known as adrenalin or adrenaline, is a naturally-produced hormone common to many animals and is responsible for increasing blood pressure, blood sugar levels, heart rate, and pupil dilation, all of which are part of the “fight or flight” response. It acts on all the tissues of the body in various ways to prepare for sudden or intense activity, and this property enables its use as medication for quickly improving circulation (in cardiac arrest), countering anaphylaxis (for severe allergic reactions), reopening constricted airways (for asthma attacks), and to modulate and prolong the effects of local anesthesia.
