Difference between Adrenergic agonist and Vasoconstriction

Adrenergic agonist vs. Vasoconstriction

An adrenergic agonist is a drug that stimulates a response from the adrenergic receptors. Vasoconstriction is the narrowing of the blood vessels resulting from contraction of the muscular wall of the vessels, in particular the large arteries and small arterioles.

Adrenaline

Adrenaline, also known as adrenalin or epinephrine, is a hormone, neurotransmitter, and medication.

Adrenergic receptor

The adrenergic receptors (or adrenoceptors) are a class of G protein-coupled receptors that are targets of the catecholamines, especially norepinephrine (noradrenaline) and epinephrine (adrenaline).

Methylphenidate

Methylphenidate, sold under various trade names, Ritalin being one of the most commonly known, is a central nervous system (CNS) stimulant of the phenethylamine and piperidine classes that is used in the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy.

Norepinephrine

Norepinephrine (NE), also called noradrenaline (NA) or noradrenalin, is an organic chemical in the catecholamine family that functions in the brain and body as a hormone and neurotransmitter.

Phenylephrine

Phenylephrine is a selective α1-adrenergic receptor agonist of the phenethylamine class used primarily as a decongestant, as an agent to dilate the pupil, to increase blood pressure, and to relieve hemorrhoids.

Protein kinase A

In cell biology, protein kinase A (PKANot to be confused with pKa, the symbol for the acid dissociation constant.) is a family of enzymes whose activity is dependent on cellular levels of cyclic AMP (cAMP).
