RESULTS. β-blocker interruption was associated with significant increase {least square mean difference [95% confidence interval (CI)]} in systolic BP [+3.7 (2.6, 4.8) mmHg, P < .001], diastolic BP [+3.3 (2.6,
The meaning of BETA-BLOCKER is any of a class of drugs (such as propranolol) that decrease the rate and force of heart contractions and lower high blood pressure by blocking the activity of beta-receptors.
Beta-blockers are very commonly prescribed as a treatment for hypertension and can decrease mortality in patients withcongestive heart failure. These medications block the β1 and β2 receptors with different selectivities, antagonize the α1 receptor, and have some vasodilating properties. Beta-block...
Some beta-blockers also bind to other receptors called alpha receptors, specifically the alpha-1 receptor. Many of these bind to B1 and B2 as well as alpha-1. These types seem to be very helpful fortreating high blood pressurebecause they have a double effect. Examples of these include: B...
Beta blockers are a group of drugs that inhibit the sympathetic activation of β-adrenergic receptors. Cardioselective blockers (e.g., atenolol, bisoprolol) primarily block β1 receptors in the hea...
Beta-blocker, any of a group of synthetic drugs used in the treatment of a wide range of diseases and conditions of the sympathetic nervous system. Stimulation by epinephrine of beta-adrenoreceptors, which are predominately found in cells of the heart an
Some beta blockers, for example, pindolol (Visken) have intrinsic sympathomimetic activity (ISA), which means they mimic the effects of epinephrine and norepinephrine and can cause an increase in blood pressure and heart rate. Beta blockers with ISA have smaller effects on heart rate than agent...
While beta-blockers may show reduced antihypertensive efficacy in African patients, the effect of beta-blockers on intraocular pressure (IOP) in African healthy volunteers is less well known.This single-masked, placebo-controlled, randomised study was conducted to investigate the response of healthy ...
is referred to as beta-blockers. Beta-blockers block the action of epinephrine, a hormone involved in the body's fight or flight response. Beta-blockers cause the heart to beat with less force and help the blood vessels to widen, thus enhancing blood flow and lowering blood pres...
abeta blocker; beta-adrenergic inhibitor that slows heart rate and decreases cardiac contractility and cardiac output, thereby lowering blood pressure; beta blockers are less effective in African Americans than they are in Caucasians; the same is true for angiotensin-converting enzyme (ACE) inhibitors...
