The 15 pages that link to Epinephrine, each with the reason it gives.

• Sympathetic nervous systemRelated: It is a blood-borne signal, unlike norepinephrine released at most sympathetic nerve endings.

• NorepinephrineRelated: A related catecholamine differs by one methylation step and has overlapping effects.

• Local anestheticRelated: It is commonly combined with selected local anesthetics to reduce absorption from the injection site.

• cAMPRelated: Some epinephrine receptors increase cAMP to change metabolism and heart activity.

• GlucagonRelated: It can support glucagon’s rapid counter-regulatory response to low glucose.

• AntihistamineCompared with: Epinephrine, not an antihistamine, is the first-line emergency treatment for anaphylaxis.

• CatecholamineBroader topic: It is the most familiar adrenal catecholamine released during acute stress.

• GlycogenRelated: It promotes glycogen breakdown, especially in liver and skeletal muscle.

• Adrenergic receptorRelated: Its broad receptor activity underlies its use in anaphylaxis and cardiac arrest.

• Local anesthesiaRelated: Added to some local anesthetics, it slows drug absorption and can prolong numbness.

• Adrenal medullaRelated: It is the adrenal medulla’s principal hormone released into blood.

• PheochromocytomaRelated: Tumor secretion can produce surges of epinephrine and related effects.

• Alpha-1 adrenergic receptorRelated: It activates alpha-1 receptors, with effects shaped by concentration and other adrenergic receptors.

• TyramineCompared with: Unlike tyramine, epinephrine acts directly at adrenergic receptors rather than mainly releasing stored norepinephrine.

• Second messenger systemBroader topic: Its receptors activate cyclic AMP signaling in tissues such as liver and heart.
