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 ...
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 ]
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]
In still other neurons in which epinephrine is the transmitter, a third enzyme phenylethanolamine N-methyltransferase (PNMT) converts norepinephrine into epinephrine. Thus, a cell that uses epinephrine as its transmitter contains four enzymes (TH, AADC, DBH, and PNMT), whereas norepinephrine neurons contain only three enzymes (lacking PNMT) and ...
Metaraminol is given intravenously as either a bolus (often 0.5–1 mg doses) or as an infusion, usually via peripheral intravenous access. Metaraminol is commonly available as 10 mg in 1 mL, that requires dilution prior to administration (often made up to a 0.5 mg/mL solution), however pre-prepared syringes of metaraminol for bolus use for ...
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 ...
[11] [3] [12] For comparison, the experimental log P values of epinephrine and norepinephrine are -1.37 and -1.24, respectively. [33] [34] Isoprenaline is used pharmaceutically as the hydrochloride and sulfate salts. [1] It is also used to a much lesser extent as the free base. [1] Isoprenaline is a racemic mixture of levorotatory and ...
Chronotropic effects (from chrono-, meaning time, and tropos, "a turn") are those that change the heart rate. Chronotropic drugs may change the heart rate and rhythm by affecting the electrical conduction system of the heart and the nerves that influence it , such as by changing the rhythm produced by the sinoatrial node .
