The four primary receptors — alpha-1, alpha-2, beta-1, and beta-2 — are located in different body areas. The impact of norepinephrine and epinephrine depend on which receptors they activate.

Seven-transmembrane receptors (7TMRs), also known as G protein-couple receptors, are the largest class of transmembrane receptors and a common target for therapeutics. Initially thought to signal ...

Auvi-Q contains epinephrine, which acts on certain receptors in the body called alpha- and beta-adrenergic receptors. By acting on these receptors, it causes the blood vessels to narrow ...

Epinephrine 0.15mg (1:2000); prefilled auto-injector; contains sulfites. Epinephrine acts on both alpha- and beta-adrenergic receptors. Through its action on alpha-adrenergic receptors ...

Beta-blockers antagonize beta-1 and beta-2 receptors which are the usual targets of the sympathetic nervous system, including epinephrine and norepinephrine. This results in a decreased heart rate ...

Supplying every AED first-aid box with epinephrine auto-injectors and naloxone can significantly increase survival rates. The opioid epidemic has persisted for a long time, and treating patients ...
