Role of Epinephrine: Sympathomimetic Bronchodilator and Vasopressor Medication for Emergency Use

Epinephrine Class

Sympathomimetic (works on alpha and beta receptors)

Epinephrine is classified as a sympathomimetic and adrenergic agonist medication. It is a non-selective agonist that acts on both alpha and beta adrenergic receptors. It is a catecholamine that is synthesized by the adrenal medulla and acts as a hormone and neurotransmitter in the body.

Epinephrine belongs to the class of medications known as bronchodilators, which help to relax the smooth muscles in the airways and widen the air passages. It is also classified as a vasopressor, which means it constricts blood vessels, leading to an increase in blood pressure.

Epinephrine is used to treat anaphylaxis, a severe and potentially life-threatening allergic reaction. It is also commonly used in emergency situations such as cardiac arrest, severe asthma attacks, and shock. Additionally, it is used in local anesthesia to constrict blood vessels and therefore decrease bleeding and prolong the anesthetic effect.

Epinephrine is available as an injectable solution, auto-injector, and inhaler. The dosage and route of administration depend on the condition being treated and the patient’s medical history. Epinephrine should only be administered by a healthcare professional and is not intended for self-administration.
