The other name for Epinephrine is Adrenalin. This is a hormone that gets produced by adrenal glands. These adrenal glands are placed at the top of each kidney. To maintain a health and sound cardiovascular system, these hormones play a very crucial role.

The emotions like anger, stress and fear may activate the release of epinephrine. On entrance of hormones into bloodstream, the following may increase such as blood pressure, heart rate, cardiac output and sugar metabolism.

Epinephrine is the active sympathomimetic hormone from the ADRENAL MEDULLA. It stimulates both the alpha- and beta- adrenergic systems, causes systemic VASOCONSTRICTION and gastrointestinal relaxation, stimulates the HEART, and dilates BRONCHI and cerebral vessels. It is used in ASTHMA and CARDIAC FAILURE and to delay absorption of local ANESTHETICS.

Therapeutic Epinephrine is the synthetic form of the naturally occurring sympathomimetic amine with vasoconstricting, intraocular pressure-reducing, and bronchodilating activities. By stimulating vascular alpha-adrenergic receptors, epinephrine causes vasoconstriction, thereby increasing vascular resistance and blood pressure. When administered in the conjunctiva, this agent binds to alpha-adrenergic receptors in the iris sphincter muscle, resulting in vasoconstriction, a decrease in the production of aqueous humor, and a lowering of intraocular pressure. Through its beta1 receptor-stimulating actions, epinephrine increases the force and rate of myocardial contraction and relaxes bronchial smooth muscle, resulting in bronchodilation.
