Epinephrine is one of the most powerful vasopressor (causing a rise in blood pressure) drugs known. It increases the strength of heart muscle contractions as well as the heart rate, and it constricts blood vessels and veins. Because it is a powerful heart stimulant, it is used in emergency medicine to restore heart rhythm in cases of shock and in certain cases of cardiac arrest (heart attack). The most common use of epinephrine in medicine is to relieve breathing distress in patients with Asthma, bronchitis, and emphysema. The synthetic catecholamine isoproterenol is also used in the treatment of these diseases.
Epinephrine is a powerful bronchodilator, meaning it relaxes bronchial muscle. It also constricts pulmonary vessels (in the lung), and inhibits the release of histamines triggered by allergic reactions.
As a bronchodilator it is most often inhaled by mouth as a spray or through another breathing apparatus. Epinephrine is also used on the skin or mucous membranes to control bleeding of wounds because it constricts blood vessels. It is sometimes used for the same reason during surgery of the nose, throat, and larynx, where it also shrinks mucosa (membranes that secrete slime), making surgery easier. Epinephrine increases metabolism, accelerates blood coagulation, and lowers pressure inside the eye in some types of glaucoma.
No, epinephrine is not a protein hormone. It is a small molecule derived from the amino acid tyrosine and acts as a neurotransmitter and hormone in the body, playing a key role in the fight or flight response.
Norepinephrine stimulates the release of adrenaline (epinephrine) from the adrenal medulla.
Epinephrine is considered both a hormone and a neurotransmitter because it is released into the bloodstream by the adrenal glands to regulate various bodily functions as a hormone, and it is also released by nerve cells in the brain and nervous system to transmit signals between neurons as a neurotransmitter.
The main hormone released during the flight or fight response is adrenaline, also known as epinephrine. This hormone is produced by the adrenal glands in response to stress or danger, preparing the body to react quickly in a threatening situation.
The first step in epinephrine signaling is the binding of epinephrine to its receptor on the cell membrane, typically a G protein-coupled receptor. This binding initiates a cascade of intracellular signaling events that ultimately lead to the desired physiological response.
epinephrine and norpepinephrine
This hormone is released during stress by adrenal medulla. This hormone gears up your body for fight or flight response.

Yes, "Epinephrine" should be capitalized as it is a proper noun referring to a specific medication or hormone.
No, epinephrine is not classified as an eicosanoid. Epinephrine is a hormone and neurotransmitter that is produced in the adrenal glands, whereas eicosanoids are signaling molecules derived from fatty acids.
