Hypernyms ("angiotensin" is a kind of...):

pressor; vasoconstrictive; vasoconstrictor (any agent that causes a narrowing of an opening of a blood vessel: cold or stress or nicotine or epinephrine or norepinephrine or angiotensin or vasopressin or certain drugs; maintains or increases blood pressure)

Hyponyms (each of the following is a kind of "angiotensin"):

angiotensin I (a physiologically inactive form of angiotensin that is the precursor to angiotensin II)

angiotensin II (a potent vasopressor agent formed from angiotensin I)

 Context examples 

This prevents the actions of the potent vasoconstrictor angiotensin II and leads to vasodilatation.

(Moexipril Hydrochloride, NCI Thesaurus)

Moexiprilat competitively inhibits ACE, thereby blocking the conversion of angiotensin I to angiotensin II.

(Moexiprilat, NCI Thesaurus)

A synthetic imidazole derivative and angiotensin II receptor antagonist with antihypertensive activity.

(Olmesartan, NCI Thesaurus)

This agent may also reduce the secretion of renin with subsequent reduction in levels of angiotensin II thereby preventing vasoconstriction and aldosterone secretion.

(Metoprolol, NCI Thesaurus)

This prevents the actions of the potent vasoconstrictor angiotensin II and leads to vasodilation.

(Moexipril, NCI Thesaurus)

The tert-butylamine salt of perindopril, the ethyl ester of a non-sulfhydryl angiotensin converting enzyme (ACE) inhibitor with antihypertensive activity.

(Perindopril Erbumine, NCI Thesaurus)

Perindoprilat inhibits ACE and, thus, the conversion of angiotensin I to angiotensin II; consequently, angiotensin II-mediated vasoconstriction and angiotensin II-stimulated aldosterone secretion from the adrenal cortex are inhibited and diuresis and natriuresis ensue.

(Perindoprilat, NCI Thesaurus)

Upon hydrolysis, the free SH metabolite of pivopril competitively binds to and inhibits ACE, thereby blocking the conversion of angiotensin I to angiotensin II.

(Pivopril, NCI Thesaurus)

Pentoprilat also decreases angiotensin II-induced aldosterone secretion by the adrenal cortex, which leads to an increase in sodium excretion and subsequently increases water outflow.

(Pentopril, NCI Thesaurus)

Olmesartan selectively binds to the angiotensin type 1 (AT1) receptor of angiotensin II in vascular smooth muscle and adrenal gland, thereby competing angiotensin II binding to the receptor.

(Olmesartan Medoxomil, NCI Thesaurus)
