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.
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. A fast heart rate and high blood pressure may occur. Occasionally it may result in an abnormal heart rhythm.
Adrenochrome is a chemical compound produced by the oxidation of adrenaline (epinephrine). It was the subject of limited research from the 1950s through to the 1970s as a potential cause of schizophrenia. While it has no current medical application, the semicarbazide derivative, carbazochrome, is a hemostatic medication.

Examples of sympathomimetic effects include increases in heart rate, force of cardiac contraction, and blood pressure. [1] The primary endogenous agonists of the sympathetic nervous system are the catecholamines (i.e., epinephrine [adrenaline], norepinephrine [noradrenaline], and dopamine ), which function as both neurotransmitters and hormones .
Ephedrine is a non-catecholamine sympathomimetic with cardiovascular effects similar to those of adrenaline/epinephrine: increased blood pressure, heart rate, and contractility. Like pseudoephedrine it is a bronchodilator , with pseudoephedrine having considerably less effect.
Provided a dentist performs proper aspiration to avoid intravenous injections, local anesthetics containing epinephrine (adrenaline) are safe to use during pregnancy. lignocaine and prilocaine are assigned a category B ranking by the FDA and are therefore safe for use during pregnancy. Lignocaine and prilocaine are sold as 2% and 4% ...
