Racepinefrine (INN Tooltip International Nonproprietary Name, USAN Tooltip United States Adopted Name), or racepinephrine, sold under the brand name Vaponefrin among others, is a sympathomimetic medication described as a vasoconstrictor, bronchodilator, cardiostimulant, mydriatic, and antiglaucoma agent.
Epinephrine, also known as adrenaline, is a medication and hormone. [10] [11] As a medication, it is used to treat several conditions, including anaphylaxis, cardiac arrest, asthma, and superficial bleeding. [8] Inhaled epinephrine may be used to improve the symptoms of croup. [12] It may also be used for asthma when other treatments are not ...
In chemistry, a racemic mixture or racemate (/ r eɪ ˈ s iː m eɪ t, r ə-, ˈ r æ s ɪ m eɪ t / [1]) is one that has equal amounts of left- and right-handed enantiomers of a chiral molecule or salt. Racemic mixtures are rare in nature, but many compounds are produced industrially as racemates.
Adrenaline, also known as epinephrine, is a hormone and medication [10] [11] which is involved in regulating visceral functions (e.g., respiration). [10] [12] It appears as a white microcrystalline granule. [13] Adrenaline is normally produced by the adrenal glands and by a small number of neurons in the medulla oblongata. [14]
Racephedrine, also known as racemic ephedrine and sold under the brand names Efetonina and Ephoxamine among others, is the racemic form of ephedrine which has been used as a bronchodilator to treat asthma.
On a case-by-case basis, the U.S. Food and Drug Administration (FDA) has allowed single enantiomers of certain drugs to be marketed under a different name than the racemic mixture. [3] Also case-by-case, the United States Patent Office has granted patents for single enantiomers of certain drugs.
A later study, by Lands and Grant, showed that a dose of ~0.6 mg/kg of racemic synephrine, given intravenously to anesthetized dogs, produced a rise in blood pressure of 34 mmHg lasting 5–10 minutes, and estimated that this pressor activity was about 1/300x that of epinephrine. [63]
The adrenergic receptors or adrenoceptors are a class of G protein-coupled receptors that are targets of many catecholamines like norepinephrine (noradrenaline) and epinephrine (adrenaline) produced by the body, but also many medications like beta blockers, beta-2 (β 2) antagonists and alpha-2 (α 2) agonists, which are used to treat high ...
