Beta blockers have also been used for the treatment of schizoid personality disorder. [105] However, there is limited evidence supporting the efficacy of supplemental beta blocker use in addition to antipsychotic drugs for treating schizophrenia. [106] [107] Contrast agents are not contraindicated in those receiving beta blockers. [108]
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]
The combination of beta blockers and antihypertensive drugs will work on different mechanism to lower blood pressure. [17] For example, the co-administration of beta-1 blocker atenolol and ACE inhibitor lisinopril could produce a 50% larger reduction in blood pressure than using either drug alone. [18]
While once a first-line treatment for hypertension, the role of beta blockers was downgraded in June 2006 in the United Kingdom to fourth-line, as they do not perform as well as other drugs, particularly in the elderly, and evidence is increasing that the most frequently used beta blockers at usual doses carry an unacceptable risk of provoking ...
Class II agents are conventional beta blockers. They act by blocking the effects of catecholamines at the β 1-adrenergic receptors, thereby decreasing sympathetic activity on the heart, which reduces intracellular cAMP levels and hence reduces Ca 2+ influx. These agents are particularly useful in the treatment of supraventricular tachycardias.
Beta 2 blockers primarily contract the smooth muscles in various tissues, particularly airway smooth muscles where beta 2 receptors are predominantly present. [5] There are currently no FDA-approved beta 2 antagonists for clinical uses. Butoxamine, an example of a beta 2 blocker, is only used in research. [5]
According to the FDA, sotalol should not be used in people with a waking heart rate lower than 50 beats per minute. [8] It should not be used in people with sick sinus syndrome, long QT syndrome, cardiogenic shock, uncontrolled heart failure, asthma or a related bronchospastic condition, or people with serum potassium below 4 meq/L. [8] It should only be used in people with a second and third ...
Acebutolol, [1] sold under the brand names Sectral among others, is a beta blocker for the treatment of hypertension and arrhythmias. Acebutolol is a cardioselective beta-1 blocker and has intrinsic sympathetic activity. It is commonly used in the treatment of angina. It was patented in 1967 and approved for medical use in 1973. [2]
