Safety of perioperative β-blocker use: how do β-blockers compare in terms of side effects?
Summary of "Safety of perioperative β-blocker use: how do β-blockers compare in terms of side effects?"
Introduction: In the perioperative setting, there is still a high incidence of adverse cardiac events due to sudden coronary plaque rupture or oxygen supply-demand imbalance. β-Blockers play an important role in preventing these cardiac events. Discussion, however, remains on the side effects accompanying this therapy. Areas covered: The evidence for perioperative use of β-blockers is summarized in this review in terms of risk reduction, perioperative safety and current clinical use. Furthermore, data on pharmacokinetics, pharmacodynamics and pharmacogenetics are presented. Expert opinion: In perioperative care, β-blockers are recommended and can be given safely when started early in a low dose, titrated to heart rate. In the future, there could be a place for added perioperative short-acting β-blockers to further optimize heart rate control.

A nicotinic antagonist that is well absorbed from the gastrointestinal tract and crosses the blood-brain barrier. Mecamylamine has been used as a ganglionic blocker in treating hypertension, but, like most ganglionic blockers, is more often used now as a research tool.
Freedom from exposure to danger and protection from the occurrence or risk of injury or loss. It suggests optimal precautions in the workplace, on the street, in the home, etc., and includes personal safety as well as the safety of property.
A calcium channel blocker with marked vasodilator action. It is an effective antihypertensive agent and differs from other calcium channel blockers in that it does not reduce glomerular filtration rate and is mildly natriuretic, rather than sodium retentive.
A nicotinic cholinergic antagonist often referred to as the prototypical ganglionic blocker. It is poorly absorbed from the gastrointestinal tract and does not cross the blood-brain barrier. It has been used for a variety of therapeutic purposes including hypertension but, like the other ganglionic blockers, it has been replaced by more specific drugs for most purposes, although it is widely used a research tool.
Activities involved in ensuring the safety of FOOD including avoidance of bacterial and other contamination.
β-Blockers clearly prolong life in patients with heart failure and after myocardial infarction in all controlled prospective trials. Nevertheless, many colleagues and even more patients fear unwanted...
PURPOSE: To evaluate the therapeutic effects of TNF-α blockers on ulcerative colitis (UC) and their safety. METHODS: Randomized controlled trials (RCTs) of TNF-α blockers for treatment of UC were re...
BACKGROUND:: Randomized controlled trials and meta-analyses provide conflicting guidance on the role of beta-adrenergic receptor blockers (beta-blockers) in reducing perioperative complications. We hy...
Introduction: β-Blockers have an important therapeutic role throughout the cardiovascular continuum. However, there is considerable variation in response to these drugs, which may be related to genet...
BACKGROUND: In an aging population, major surgery is often performed in patients with complex co-morbidities. These patients present new risk constellations so that cardiac and respiratory complicatio...
Beta-blockers are prescribed to millions of people for treatment of hypertension. Fatigue is a recognized and common side effect of beta-blockers that can have significant effects on quali...
The study compares three treatment modalities in a human model of Postural orthostatic tachycardia syndrome (POTS): beta-blockers, I(f)-blockers, and placebo.
Studies have shown that beta-blockers such as atenolol when given in the perioperative period reduce morbidity and mortality. One study showed that atenolol given just during the surgery...
Several large trials have shown that beta-blocker treatment reduces the risk of death and hospital admission in patients with symptomatic heart failure. Unfortunately, survey data suggest...
Smoking causes both smoking related lung disease (COPD) and ischaemic heart disease. These are very common conditions and many patients have both diseases. Beta-blocker drugs are extensi...
