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 ...
Ultimately, release of noradrenaline and epinephrine will be inhibited and smooth muscles tend to dilate. [3] Alpha-2 blocker stops the downstream signaling pathway (inhibit adenylyl cyclase, reduce cAMP and Ca), thus lead to release of the mentioned neurotransmitters( noradrenaline and epinephrine ) and contraction of smooth muscle eventually.
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.
Epinephrine (adrenaline) (1 in 1,000) is the primary treatment for anaphylaxis with no absolute contraindication to its use. [9] It is recommended that an epinephrine solution be given intramuscularly into the mid anterolateral thigh as soon as the diagnosis is suspected.
Medications recommended in the ACLS protocol include epinephrine, amiodarone, and lidocaine. [9] The timing and administration of these medications depends on the underlying arrhythmia of the arrest. Epinephrine acts on the alpha-1 receptor, which in turn increases the blood flow that supplies the heart. [ 106 ]
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 ]
In medicine, a contraindication is a condition (a situation or factor) that serves as a reason not to take a certain medical treatment due to the harm that it would cause the patient. [ 1 ] [ 2 ] Contraindication is the opposite of indication , which is a reason to use a certain treatment.
Visual definition of an antagonist, where it compared to agonists and reverse agonists. An adrenergic antagonist is a drug that inhibits the function of adrenergic receptors. There are five adrenergic receptors, which are divided into two groups. The first group of receptors are the beta (β) adrenergic receptors. There are β 1, β 2, and β 3 ...
