Beta-adrenergic agonists

Adrenaline, also known as epinephrine and alternatively spelled adrenalin, is a hormone and medication which is involved in regulating visceral functions (e.g., respiration). It appears as a white microcrystalline granule. Adrenaline is normally produced by the adrenal glands and by a small number of neurons in the medulla oblongata. It plays an essential role in the fight-or-flight response by increasing blood flow to muscles, heart output by acting on the SA node, pupil dilation response, and blood sugar level. It does this by binding to alpha and beta receptors. It is found in many animals,

Norepinephrine (NE), also called noradrenaline (NA) or noradrenalin, is an organic chemical in the catecholamine family that functions in the brain and body as a hormone, neurotransmitter and neuromodulator. The name "norepinephrine" (from Ancient Greek ἐπῐ́ (epí), "upon", and νεφρός (nephrós), "kidney") is usually preferred in the United States, whereas "noradrenaline" (from Latin ad, "near", and ren, "kidney") is more commonly used in the United Kingdom and the rest of the world. "Norepinephrine" is also the international nonproprietary name given to the drug. Regardless of which name is use

Salbutamol, also known as albuterol and sold under the brand name Ventolin among others, is a medication that opens up the medium and large airways in the lungs. It is a short-acting β2 adrenergic receptor agonist that causes relaxation of airway smooth muscle. It is used to treat asthma, including asthma attacks and exercise-induced bronchoconstriction, as well as chronic obstructive pulmonary disease (COPD). It may also be used to treat high blood potassium levels. Salbutamol is usually used with an inhaler or nebulizer, but it is also available in a pill, liquid, and intravenous solution. O

Methyldopa, also known as α-methyl-L-DOPA and sold under the brand name Aldomet among others, is a medication used for high blood pressure. It is one of the preferred treatments for high blood pressure in pregnancy. For other types of high blood pressure including very high blood pressure resulting in symptoms other medications are typically preferred. It can be given by mouth or injection into a vein. Onset of effects is around 5 hours and they last about a day.

Etilefrine, sold under the brand name Effortil among others, is a sympathomimetic medication used as an antihypotensive agent to treat orthostatic hypotension. It is usually used by mouth, but is also available as an injectable.

Droxidopa, also known as 'L-threo-dihydroxyphenylserine (L-DOPS) and sold under the brand names Northera and Dops' among others, is sympathomimetic medication which is used in the treatment of hypotension (low blood pressure) and for other indications. It is taken by mouth.

Dipivefrine, or dipivefrin, also known as epinephrine pivalate and sold under the brand name Propine among others, is a sympathomimetic medication which is used in the treatment of open-angle glaucoma. It is available as a 0.1% ophthalmic solution (eye drop).

class of compounds

Metaraminol, also known as metaradrine and sold under the brand name Aramine among others, is a sympathomimetic medication which is used in the prevention and treatment of hypotension (low blood pressure), particularly as a complication of anesthesia. It is given by intramuscular or intravenous administration.

Hexoprenaline is a selective β2 adrenergic receptor agonist used in the treatment of asthma. Hexoprenaline is also used in some countries (such as Russia and Switzerland) as a tocolytic agent (i.e., labor suppressant), with the most common trade name being Gynipral. It is not approved by the United States Food and Drug Administration.

Corbadrine, sold under the brand name Neo-Cobefrine and also known as levonordefrin and α-methylnorepinephrine, is a catecholamine sympathomimetic used as a topical nasal decongestant and vasoconstrictor in dentistry in the United States. It is usually used in a pre-mixed solution with local anesthetics, such as mepivacaine.

Isoxsuprine (used as isoxsuprine hydrochloride) is a drug used as a vasodilator in humans (under the trade name Duvadilan) and equines. Isoxsuprine is a β2 adrenoreceptor agonist that causes direct relaxation of uterine and vascular smooth muscle via β2 receptors.

use of epinephrine as medication

Reproterol is a short-acting β2 adrenoreceptor agonist used in the treatment of asthma.

Rimiterol (INN/USAN) is a third-generation short-acting β2 agonist.

Dopexamine is a synthetic analogue of dopamine that is administered intravenously in hospitals to reduce exacerbations of heart failure and to treat heart failure following cardiac surgery. It is not used often, as more established drugs like epinephrine, dopamine, dobutamine, norepinephrine, and levosimendan work as well. It works by stimulating beta-2 adrenergic receptors and peripheral dopamine receptor D1 and dopamine receptor D2. It also inhibits the neuronal re-uptake of norepinephrine.

combination drug

Deoxyepinephrine, also known by the common names '''N-methyldopamine and epinine''', is an organic compound and natural product that is structurally related to the important neurotransmitters dopamine and epinephrine. All three of these compounds also belong to the catecholamine family. The pharmacology of epinine largely resembles that of its "parent", dopamine. Epinine has been found in plants, insects and animals. It is also of significance as the active metabolic breakdown product of the prodrug ibopamine, which has been used to treat congestive heart failure.

Oxyfedrine, sold under the brand names Ildamen and Myofedrin among others, is a sympathomimetic agent and coronary vasodilator which is used in the treatment of coronary heart disease, angina pectoris, and acute myocardial infarction. It is taken by mouth or intravenously.

Isoetharine is a selective short-acting β2 adrenoreceptor agonist. It can be called the "granddaughter of adrenalin" in the line of β2 agonists that gave quick relief for bronchospasm and asthma. Epinephrine (adrenalin) was the first of these, and next came isoprenaline (isoproterenol). Isoetharine was the third drug in this line, thus the third generation or granddaughter of the original.

Arbutamine is a cardiac stimulant. It stimulates β adrenergic receptors.

Ibopamine is a sympathomimetic drug, designed as a prodrug of epinine (deoxyepinephrine or N-methyldopamine), used in ophthalmology. It induces mydriasis. It also has been investigated for use in the treatment of congestive heart failure.
