 Context examples: 

Clinically, norepinephrine is used as a peripheral vasoconstrictor that causes constriction of arterial and venous beds via its alpha-adrenergic action.

(Norepinephrine Bitartrate, NCI Thesaurus)

Norepinephrine acts directly on the alpha- and beta-adrenergic receptors.

(Norepinephrine, DL-, NCI Thesaurus)

Nortriptyline also binds to alpha-adrenergic, histaminergic and cholinergic receptors.

(Nortriptyline, NCI Thesaurus)

Nebivolol binds to and blocks the beta-1 adrenergic receptors in the heart, thereby decreasing cardiac contractility and rate.

(Nebivolol, NCI Thesaurus)

A non-selective beta-adrenergic antagonist with antihypertensive and antiarrhythmic activities.

(Nadolol, NCI Thesaurus)

Although its mechanism of action is unknown, mirtazapine enhances central adrenergic and serotonergic transmission, possibly by acting as an antagonist at central presynaptic alpha 2 adrenergic inhibitory autoreceptors and heteroreceptors.

(Mirtazapine, NCI Thesaurus)

Upon ocular administration, naphazoline exerts its effect by acting on alpha-adrenergic receptors in the arterioles of the conjunctiva to produce vasoconstriction, resulting in decreased conjunctival congestion and diminished itching, irritation and redness.

(Naphazoline, NCI Thesaurus)

Upon ocular administration, naphazoline hydrochloride exerts its effect by acting on alpha-adrenergic receptors in the arterioles of the conjunctiva to produce vasoconstriction, resulting in decreased conjunctival congestion and diminished itching, irritation and redness.

(Naphazoline Hydrochloride, NCI Thesaurus)

Alpha-1B adrenergic receptor (520 aa, 57 kD) is a cell division process protein that is encoded by the human ADRA1B gene and has roles in multicellular organismal development, cell proliferation and cell signaling.

(Alpha-1B Adrenergic Receptor, NCI Thesaurus)

This allele, which encodes beta-adrenergic receptor kinase 1 protein, plays a role in the phosphorylation of the activated form of the beta-adrenergic and related G-protein-coupled receptors.
