Angiotensin II Receptor Antagonists
ACE inhibitors possess many common characteristics with another class of cardiovascular drugs, angiotensin II receptor antagonists, which are often used when patients are intolerant of the adverse effects produced by ACE inhibitors. ACE inhibitors do not completely prevent the formation of angiotensin II, as blockage is dose-dependent, so angiotensin II receptor antagonists may be useful because they act to prevent the action of angiotensin II at the AT1 receptor, leaving AT2 receptor unblocked; the latter may have consequences needing further study.

Famous quotes containing the words receptor and/or antagonists:
“The disinterest [of my two great-aunts] in anything that had to do with high society was such that their sense of hearing ... put to rest its receptor organs and allowed them to suffer the true beginnings of atrophy.”
—Marcel Proust (1871–1922)
“There is a persuasion in the soul of man that he is here for cause, that he was put down in this place by the Creator to do the work for which he inspires him, that thus he is an overmatch for all antagonists that could combine against him.”
—Ralph Waldo Emerson (1803–1882)
