"WebEither alpha or beta-adrenergic receptors will receive and be activated by the norepinephrine. The difference in receptor type alpha or beta will determine the response which can include vasodilation or vasoconstriction. This opposing response to the same neurotransmitter is key to the fight or flight reaction, as we will see next. " - Norepinephrine alpha or beta

Epinephrine vs. norepinephrine: What to know - Medical News …

WebEpinephrine. Epinephrine (also known as adrenaline) is also a monoamine and catecholamine. It is produced in the final step of conversion of tyrosine. Thus, the complete cycle is evident when tyrosine is gradually converted by various enzymes into L-Dopa, then dopamine, then norepinephrine, and then epinephrine. WebAlpha-Adrenoceptor properties were substantially modified by N-substitution, whereas aromatic substitution was an important factor in determining beta-adrenoceptor agonist …

My guess would be because of norepinephrine receptor affinity. alpha 1 > beta 1 > beta 2. So at low doses, when it is only affecting alpha 1 and beta 1 receptors, it doesn't change pulse pressure. At higher doses, it affects the beta 2 receptors causing some peripheral vasodilation and widening the pulse pressure. scramble networkWebNorepinephrine can then go on to bind three main receptors: alpha1 (alpha-1), alpha-2, and beta receptors.
