Adrenaline medication used to treat severe allergic reactions including anaphylaxis and insect sting reactions.
A catecholamine hormone secreted from the adrenal medulla in response to various stressors.
A substance produced by the medulla (inside) of the adrenal gland. The name epinephrine was coined in 1898 by the American pharmacologist and physiologic chemist (biochemist) John Jacob Abel who isolated it from the adrenal gland which is located above (epi-) the kidney ("nephros" in Greek). (Abel also crystallized insulin). Technically speaking, epinephrine is a sympathomimetic catecholamine. It causes quickening of the heart beat, strengthens the force of the heart's contraction, opens up the airways (bronchioles) in the lungs and has numerous other effects. The secretion of epinephrine by the adrenal is part of the fight-or-flight reaction. Adrenaline is a synonym of epinephrine and is the official name in the British Pharmacopoeia.

Epinephrine is a hormone and neurotransmitter and is referred to as a catecholamine. It is synthesized from the amino acid tyrosine. Epinephrine triggers the breakdown of glycogen by activating adenylate cyclase and increasing the cellular levels of cAMP. This in turn activates a phosphorylation cascade leading to the activation of glycogen phosphorylase and the inhibition of glycogen synthase. The structure of epinephrine is shown below.
This is one of several chemicals (another is norepinephrine) released by the adrenal gland to increase heart rate.
Epinephrine (also called adrenaline) is a hormone secreted by the adrenal medulla section of the adrenal gland and released primarily in response to hypoglycemia; it is also produced as a synthetic drug. A powerful vasopressor substance, epinephrine acts to increase blood pressure and stimulate the heart muscle, accelerating the heart rate and increasing cardiac output.
also called adrenaline. Hormone synthesized by the medulla of the adrenal gland. responsible, in part, for the "fight or flight" response.
A form of adrenaline medication used to treat severe allergic reactions, such as anaphylactic shock or insect stings. It is available in self-injectable form or can be injected by a health care provider.
A naturally occurring hormone, also called adrenaline. It is one of two chemicals (the other is norepinephrine) released by the adrenal gland medulla. Epinephrine increases the speed and force of heart beats, dilates the airways to improve breathing, and narrows blood vessels in the skin and intestines to increase blood flow to the muscles. Epinephrine has been produced synthetically as a drug since 1900 and is the drug of choice for treatment of anaphylaxis (severe allergic reactions).

Epinephrine (INN) or adrenaline (BAN) is a hormone and a neurotransmitter. A neurotransmitter is a specific kind of hormone, released by neurons to regulate activity of target tissues (e.g. brain cells, muscle cells,...). The Latin roots ad-+renes and the Greek roots epi-+nephros both literally mean "on/to the kidney" (referring to the adrenal gland, which secretes epinephrine). Epinephrine is sometimes shortened to epi in medical jargon.
Hormone produced by the adrenal gland increasing blood pressure and heartbeat.
Catecholamine hormone synthesized in adrenal medulla ( Ch. 10); also a neurotransmitter synthesized in the brainstem ( Chs 14, 21). Also known as adrenaline.
The principal hormone secreted by the adrenal medulla in response to stressful situations. Its effects are similar to those brought about by stimulation of the sympathetic division of the autonomic nervous system (for example, arousal, increased heart rate and blood pressure). It is also an excitatory neurotransmitter in the central nervous system (syn. adrenalin). See also adrenal gland, norepinephrine.
hormone secreted principally by the adrenal medulla with a wide variety of functions, such as stimulating the heart, making carbohydrates available in the liver and muscles, and releasing fat from fat cells
Another term for adrenaline.
