Definition of beta blocker in English English dictionary
A blocking agent, one of a class of drugs used to treat hypertension and control the rate at which the heart beats
A drug that slows heart rate, lowers blood pressure, controls angina and protects patients with prior heart attacks from future heart attacks
an antihypertensive medication that limits the activity of epinephrine (hormone that increases blood pressure)
An antihypertensive drug that limits the activity of epinephrine, a hormone that increases blood pressure
A beta blocker is a drug which is used to treat people who have high blood pressure or heart problems
an antihypertensive medication that limits the activity of epinephrine (a hormone that increases blood pressure)
a drug that blocks the effect of catecholamines, producing a decrease in heart rate and oxygen demand in the myocardium
a medication that limits the activity of epinephrine (a hormone that increases blood pressure)
Drugs that block the action of certain hormones on the heart Beta blockers reduce the heart rate and the force of muscle contraction, thereby reducing the oxygen demand of heart muscles
any of various drugs used in treating hypertension or arrhythmia; decreases force and rate of heart contractions by blocking beta-adrenergic receptors of the autonomic nervous system
in full beta-adrenergic blocking agent Any of a class of synthetic drugs used to treat a wide range of diseases and conditions of the sympathetic nervous system (see autonomic nervous system). Stimulation by epinephrine of beta-adrenergic receptors, which are predominately found in the heart but are also present in vascular and other smooth muscle, results in excitation of the sympathetic nervous system. By preventing that excitation, beta-blockers are useful in controlling anxiety, hypertension, and a variety of heart conditions (see heart disease). They reduce the risk of a second heart attack
(Medicine) drug that blocks stress hormones by hindering the activity of beta receptors in the body (used to treat hypertension, angina, and other heart conditions)
