Beta blockers are known primarily for their reductive effect on heart rate, although this is not the only mechanism of action of importance in congestive heart failure. [17] Beta blockers, in addition to their sympatholytic β 1 activity in the heart, influence the renin–angiotensin system at the kidneys.
Bisoprolol, sold under the brand name Zebeta among others, is a beta blocker which is selective for the beta-1 receptor [7] and used for cardiovascular diseases, [7] including tachyarrhythmias, high blood pressure, angina, and heart failure. [7] [8] It is taken by mouth. [7]
Landiolol, sold under the brand name Onoact among others, is a medication used for the treatment of tachycardia, atrial fibrillation, and atrial flutter. [1] [4] It is a beta-adrenergic blocker; [4] an ultra short-acting, β1-superselective intravenous adrenergic antagonist, which decreases the heart rate effectively with less negative effect on blood pressure or myocardial contractility.
Beta blockers work by blocking the effects of adrenaline, aka slowing your heart rate and reducing those physical signs and symptoms of nervousness and anxiety, he explained.
By reducing sympathetic stimulation of the heart, beta blockers decrease heart rate, blood pressure and cardiac output, and hence heart oxygen consumption. Beta-blockers alleviate ischemic pain, and have also been proved to reduce the size of infarcted heart muscle, the risk of arrhythmias, and the proportion of patients with acute coronary ...
Labetalol is often classified as a beta blocker with low lipophilicity and hence lower potential for crossing the blood–brain barrier and blood–placenta barrier. [ 17 ] [ 29 ] [ 30 ] This in turn may result in fewer effects in the central nervous system as well as a lower risk of neuropsychiatric side effects. [ 17 ]
Atenolol is a beta blocker medication primarily used to treat high blood pressure and heart-associated chest pain. [7] Although used to treat high blood pressure, it does not seem to improve mortality in those with the condition. [8] [9] Other uses include the prevention of migraines and treatment of certain irregular heart beats.
Anticoagulants: To prevent embolization.. Beta blockers: To block the effects of certain hormones on the heart to slow the heart rate.. Calcium Channel Blockers: Help slow the heart rate by blocking the number of electrical impulses that pass through the AV node into the lower heart chambers (ventricles).
