Epinephrine is also used as a bronchodilator for asthma if specific β 2 agonists are unavailable or ineffective. [39] Because of the high intrinsic efficacy (receptor binding ability) of epinephrine, high drug concentrations cause adverse side effects when treating asthma. The value of using nebulized epinephrine in acute asthma is unclear. [40]
Metanephrine, also known as metadrenaline, is a metabolite of epinephrine (also known as adrenaline) created by action of catechol-O-methyl transferase on epinephrine. An article in the Journal of the American Medical Association, 2002, indicated that the measurement of plasma free levels of the metanephrines group of molecules (including metanephrine and normetanephrine) is the best tool in ...
The mechanisms of sympathomimetic drugs can be direct-acting (direct interaction between drug and receptor), such as α-adrenergic agonists, β-adrenergic agonists, and dopaminergic agonists; or indirect-acting (interaction not between drug and receptor), such as MAOIs, COMT inhibitors, release stimulants, and reuptake inhibitors that increase the levels of endogenous catecholamines.
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]
The US Food and Drug Administration approved the first nasal spray epinephrine drug for severe allergic reactions known as anaphylaxis, providing a needle-free alternative to EpiPens and similar ...
Norepinephrine Epinephrine. A norepinephrine reuptake inhibitor (NRI, NERI) or noradrenaline reuptake inhibitor or adrenergic reuptake inhibitor (ARI), is a type of drug that acts as a reuptake inhibitor for the neurotransmitters norepinephrine (noradrenaline) and epinephrine (adrenaline) by blocking the action of the norepinephrine transporter (NET).
These drugs inhibit the uptake of the neurotransmitter 5-HT by blocking the SERT, thus increasing its synaptic concentration, and have shown to be efficacious in the treatment of depression, however sexual dysfunction and weight gain are two very common side-effects that result in discontinuation of treatment.
Dopamine, sold under the brand name Intropin among others, is a medication most commonly used in the treatment of very low blood pressure, a slow heart rate that is causing symptoms, and, if epinephrine is not available, cardiac arrest. [4] In newborn babies it continues to be the preferred treatment for very low blood pressure. [5]
