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]
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.
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 ]
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 ...
Some medications are formulated as injector pens to quicken the onset of action of the medication. This includes epinephrine, which when used to treat anaphylaxis must work as soon as possible. [19] Contrary to most other injector pens, epinephrine injector pens are designed to administer the medication via intramuscular injection. [19]
Epinephrine autoinjectors are often prescribed to people who are at risk for anaphylaxis. Brand names include Anapen, EpiPen, Emerade, and Auvi-Q. [ citation needed ] Rebiject, Rebiject II and Rebidose autoinjectors for Rebif , the drug for interferon beta-1a used to treat multiple sclerosis .
Type I hypersensitivity (or immediate hypersensitivity), in the Gell and Coombs classification of allergic reactions, is an allergic reaction provoked by re-exposure to a specific type of antigen referred to as an allergen. [1] Type I is distinct from type II, type III and type IV hypersensitivities. The relevance of the Gell and Coombs ...
Some patients request to be switched to a different narcotic due to stigma associated with a particular drug (e.g. a patient refusing methadone due to its association with opioid addiction treatment). [4] Equianalgesic charts are also used when calculating an equivalent dosage of the same drug, but with a different route of administration.
