An epinephrine autoinjector (or adrenaline autoinjector, also known by the trademark EpiPen) is a medical device for injecting a measured dose or doses of epinephrine (adrenaline) by means of autoinjector technology. It is most often used for the treatment of anaphylaxis. The first epinephrine autoinjector was brought to market in 1983.
The "Auvi-Q" epinephrine autoinjector uses this design. [8] A newer variant of the autoinjector is the gas jet autoinjector, which contains a cylinder of pressurized gas and propels a fine jet of liquid through the skin without using a needle. This has the advantage that patients who fear needles are more accepting of using these devices.

Adrenergic receptor autoantibodies. The adrenergic receptors (or adrenoreceptors) are a class of cell membrane-bound protein receptors throughout the body that are targets of the catecholamines, especially norepinephrine (or noradrenaline) and epinephrine (or adrenaline).
An injector pen consists of a chamber or cartridge of medication, a tip to attach a needle, and a piston or plunger to inject the dose. [4] Some pens, including most insulin pens, include dials to adjust the dose of the injection before each administration. [2]
There is an epinephrine metered-dose inhaler sold over the counter in the United States to relieve bronchial asthma. [67] [68] It was introduced in 1963 by Armstrong Pharmaceuticals. [69] A common concentration for epinephrine is 2.25% w/v epinephrine in solution, which contains 22.5 mg/mL, while a 1% solution is typically used for aerosolization.
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 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 ...
