Epinephrine (INN) or adrenaline (BAN) is a hormone and a neurotransmitter. 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. Chemically, epinephrine is a catec ...

Epinephrine plays a central role in the short-term stress reaction—the physiological response to threatening or exciting conditions (see fight-or-flight response). It is secreted by the adrenal medulla. When released into the bloodstream, epinephrine binds to multiple receptors and has numerous effects throughout the body. It increases heart rate and stroke volume, dilates the pupils, and constricts arterioles in the skin and gut while dilating arterioles in leg muscles. It elevates the blood sugar level by increasing hydrolysis of glycogen to glucose in the liver, and at the sam ...

An adrenergic is a drug, or other substance, which has effects similar to, or the same as, epinephrine (adrenaline). Alternatively, it may refer to something which is susceptible to epinephrine, or similar substances, such as a biological receptor (specifically, the adrenergic receptors). Beta blockers block the action of epinephrine in the body. Other related archivesBeta blockers, adrenergic receptors, drug, epinephrine, receptor

Epinephrine's actions are mediated through adrenergic receptors (sometimes referred to as adrenoceptors). It binds to α1 receptors of liver cells, which activate inositol-phospholipid signaling pathway, signaling the phosphorylation of insulin, leading to reduced ability of insulin to bind to its receptors. Epinephrine also activates β-adrenergic receptors of the liver and muscle cells, thereby activating the adenylate cyclase signaling pathway, ...

The sympathetic nervous system activates what is often termed the "fight or flight response". This response is also known as sympathico-adrenal response of the body, as the pre-ganglionic sympathetic fibers that end in the adrenal medulla (but also all other sympathetic fibers) secrete acetylcholine, which activates the secretion of epinephrine and to a lesser extent norepinephrine from it. Therefore this response that acts primarily on the cardiovascular system is mediated directly via impulses transmitted through the sympathetic nervous system and indirectl ...

Catechol-O-methyl transferase (COMT) (EC 2.1.1.6) is an enzyme first discovered by biochemist Julius Axelrod. COMT is the name given to the gene which codes for this enzyme. The O in the name stands for the ortho position of the methyl group. Catechol-O-methyl transferase is involved in the breakdown of the catecholamine neurotransmitters, dopamine, epinephrine and norepinephrine. The enzyme introduces a methyl group t ...

Beta blockers or beta-adrenergic blocking agents are a class of drugs used to treat a variety of cardiovascular conditions and some other diseases. Beta blockers block the action of epinephrine and norepinephrine on the β-adrenergic receptors in the body (primarily in the heart, peripheral blood vessels, bronchi, pancreas, and liver). The hormones and neurotransmitters stimulate the sympa ...

Catecholamines are chemical compounds derived from the amino acid tyrosine that act as hormones or neurotransmitters. They are examples of phenethylamines. Catecholamines are soluble, and so they can circulate dissolved in blood. The most abundant catecholamines are epinephrine (adrenaline), norepinephrine (noradrenaline) and dopamine. They are produced mainly from the adrenal medulla and the postganglionic fibers of the sympathetic nervous system. Adrenaline acts as a neurotransmitter in the central nervous system and a ...

A United States Approved Name (USAN) is the official non-proprietary or generic name given to a pharmaceutical substance, as defined in the United States Pharmacopeia (USP). Some people in the United Kingdom, unhappy with the transition to International Nonproprietary Names (INNs), believe that the INNs were formulated with a heavy bias towards USANs over the former British Approved Names (BANs). Of main contention is the selection of epinephrine over adrenaline (BAN); however there are many other instances where the BAN ...

Clinical death occurs when a patient's heartbeat and breathing have stopped. The reversal of this state is possible through CPR, Defibrillation, Epinephrine injection, and other treatments. Resuscitation after more than 4 to 6 minutes of clinical death at normal body temperature is difficult, and can result in brain damage or brain death. Longer intervals of clinical death can be survived under conditions of Hypothermia. Hypothermia also improves outcomes after resuscitation from clinical death even if body ...

The adrenergic receptors (or adrenoceptors) are a class of G- protein coupled receptors that is the target of catecholamines. Adrenergic receptors specifically bind their endogenous ligands, the catecholamines adrenaline and noradrenaline (also called epinephrine and norepinephrine) and are activated by these. Many cells possess these receptors, and the binding of an agonist will generally cause the cell to respond in a flight-fight manner. For instance, the he ...

The sympathetic nerves emerge near the spinal cord, inside the vertebral column, travelling along the path of the nerve roots. After a few twists and turns, sympathetic nerves branch off and travel into major organs, glands, and other groupings of nerves (called ganglia).

Because its cells begin ...

Clonidine is a centrally-acting alpha-2 agonist. It selectively stimulates receptors in the brain that monitor catecholamine levels in the blood. These receptors close a feedback loop that begins with descending sympathetic nerves from the brain that control the production of catecholamines (epinephrine, also known as adrenaline, and norepinephrine) in the adrenal medulla. By fooling the brain into believing that catecholamine levels are higher than they really are, clonidine causes the brain to reduce its signals to the adrenal medulla, whi ...

Propranolol (Inderal®) is a non-selective beta blocker (i.e. it blocks the action of epinephrine on both β1- and β2-adrenoreceptors). It is well and rapidly absorbed after oral dosing with maximal plasma levels observed 1 to 2 hours after application (to fasting patient). Propranolol has a low and variable bioavailability due to extensive first-pass-metabolism. Liver disease will therefore increase bioavailability and pharmacologic actions. The active metabolite 4-Hydroxypropranolol, having a somewhat s ...

Most patients present with diarrhea after ingesting certain foodstuffs, skin symptoms (rashes), bloating, vomiting and regurgitation. The digestive complaints usually develop within half an hour of ingesting the allergen. Rarely, food allergy can lead to anaphylactic shock: hypotension (low blood pressure) and loss of consciousness. This is a medical emergency. Allergens commonly associated with this type of reaction are peanut and shellfish, although latex products can induce similar reactions. Initial treatment is with epinephrine (adrenalin), often c ...
