Definitions related to adrenergic beta-antagonists:
-
(beta blockers) A class of drugs that slow the heartbeat, lessen the force of each contraction, and reduce the contraction of blood vessels in the heart, brain, and throughout the body by blocking the action of beta-adrenergic substances such as adrenaline (epinephrine) at the beta receptor. Beta blockers, also known as beta adrenergic blocking agents, are used to treat many cardiovascular conditions, including abnormal heart rhythms, angina, and high blood pressure. They also improve survival after a heart attack.Harvard Dictionary of Health TermsHarvard Medical Publishing, 2011
-
(beta-adrenergic antagonist) Natural or synthetic beta adrenergic antagonists selectively or non-selectively blocking or diminishing physiologic beta-adrenergic agonist actions on the sympathetic system. This group of antagonists are generally used for treatment of hypertension, cardiac arrhythmias, angina pectoris, glaucoma, migraine headaches, and anxiety.NCI ThesaurusU.S. National Cancer Institute, 2021
-
Drugs that bind to but do not activate beta-adrenergic receptors thereby blocking the actions of beta-adrenergic agonists. Adrenergic beta-antagonists are used for treatment of hypertension, cardiac arrhythmias, angina pectoris, glaucoma, migraine headaches, and anxiety.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
