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 ...
The fight for terminology between adrenaline and epinephrine was not ended until the first adrenaline structural discovery by Hermann Pauly (1870–1950) in 1903 and the first adrenaline synthesis by Friedrich Stolz (1860–1936), a German chemist in 1904. They both believed that Takamine's compound was the active principle while Abel's ...
In general, pure beta-adrenergic agonists have the opposite function of beta blockers: beta-adrenoreceptor agonist ligands mimic the actions of both epinephrine- and norepinephrine- signaling, in the heart and lungs, and in smooth muscle tissue; epinephrine expresses the higher affinity.
Visual definition of an antagonist, where it compared to agonists and reverse agonists. An adrenergic antagonist is a drug that inhibits the function of adrenergic receptors.
Namely, those counter-regulatory mechanisms are glucagon and epinephrine. The process of the regulation of blood glucose (also known as glucose homeostasis ) also exhibits oscillatory behavior . On a pathological basis, this topic is crucial to understanding certain disorders in the body such as diabetes , hyperglycemia and hypoglycemia .
Doses higher than 1 mg of epinephrine are not recommended for routine use in cardiac arrest. If the person has a non-shockable rhythm, such as asystole, following an initial round of CPR, 1 mg of epinephrine should be given every 3–5 minutes, with the goal of obtaining a shockable rhythm.
Tainter further quantified the pressor activity of epinine in atropine-treated and anesthetized intact cats, showing that doses of 0.02-0.2 mg, given i.v., were about 1/12 as active as l-epinephrine, but that the effect lasted about twice as long (~ 3 minutes), and was accompanied by an increase in pulse rate.

Benign prostatic hyperplasia (BPH) is an enlarged prostate gland.Alpha-1 blockers are the most commonly used medicine to treat BPH. [6] Alpha-1 blockers are first line treatment for the symptoms of BPH in men.
