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.
Inhaled epinephrine may be used to improve the symptoms of croup. [12] It may also be used for asthma when other treatments are not effective. [8] It is given intravenously, by injection into a muscle, by inhalation, or by injection just under the skin. [8] Common side effects include shakiness, anxiety, and sweating. [8]
Intramuscular injection, often abbreviated IM, is the injection of a substance into a muscle. In medicine , it is one of several methods for parenteral administration of medications. Intramuscular injection may be preferred because muscles have larger and more numerous blood vessels than subcutaneous tissue, leading to faster absorption than ...
An injection of Auvi-Q autoinjector. Another design has a shape and size of a smartphone which can be put into a pocket. This design also has a retractable needle and automated voice instructions to assist the users on how to correctly use the autoinjector. The "Auvi-Q" epinephrine autoinjector uses this design. [8]
Most injector pens are designed for subcutaneous injection just under the skin, but some are designed for injection into muscle. The desired injection site and the skin profile at the injection site will determine what needle length is appropriate for a person to use. [23] For products with included needles, such as epinephrine pens, different ...
The practice of intracardiac injection originated in the 1800s. It was commonly performed during the 1960s, as it was considered the fastest way to get medication to the heart. The practice began declining during the 1970s as more reliable delivery methods (i.e., intravenous , endotracheal , and intraosseous ) came into use.
For example, high levels of adrenaline cause smooth muscle relaxation in the airways but causes contraction of the smooth muscle that lines most arterioles. Adrenaline is a nonselective agonist of all adrenergic receptors, including the major subtypes α 1, α 2, β 1, β 2, and β 3. [73]
Findings indicate that β 2 stimulants, especially in parenteral administration such as inhalation or injection, can induce adverse effects: Tachycardia secondary to peripheral vasodilation and cardiac stimulation (Such tachycardia may be accompanied by palpitations.) [4] Tremor, excessive sweating, anxiety, insomnia, and agitation [5]
