Common side effects of all beta-blockers include: Slow heart rate (bradycardia)

As a member of the beta-blocker class, labetalol is contraindicated, and its use is strongly cautioned in patients with bronchial asthma, overt cardiac failure, greater-than-first degree heart block, cardiogenic shock, severe bradycardia, as well as other
Cardioselective beta-blockers (eg, acebutolol, atenolol, metoprolol, and penbutolol) may be safer than nonselective beta-blockers
High
The major side effects associated with the use of beta blockers will be reviewed here
Discuss the evaluation of a patient with beta-blocker toxicity
β-blockers are competitive (often highly selective) antagonists of β-adrenoreceptors
Beta-blockers vary in the degree of elimination by the kidney or the liver, usually with extensive first-pass metabolism
atenolol are cleared by the kidney
It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure
β-blockers are a mainstay of HF therapy (Yancy et al
1 Historically, β-blockers had been recommended as one of the first-line treatment options for primary hypertension by the Joint National Committee on Detection, Evaluation, and Treatment of High Blood Pressure from its first
Labetalol hydrochloride , celiprolol hydrochloride , carvedilol , and nebivolol are beta-blockers that have, in addition, an arteriolar vasodilating action, by diverse Mechanism of Action
The arylethanolamines, (top) include labetalol, arotinolol, and amosulalol Beta-Blockers may enhance the rebound hypertensive effect of Alpha2-Agonists
Alpha and beta dual receptor blockers are a subclass of beta blockers which are commonly used to treat high blood pressure (BP)
min -1
Atenolol is a second-generation beta-1–selective adrenergic antagonist that helps lower the heart rate and blood pressure of an individual while also decreasing myocardial contractility
Response to treatment can be seen in up to 4 weeks and is more rapid than with beta-blockers
The mixed beta/alpha blocker labetalol is safe and effective for treating concomitant cocaine-induced hypertension Labetalol may cause serious side effects
Esmolol, propranolol, labetalol, metoprolol, atenolol or carvedilol regardless of dose, duration or route of administration: In-hospital mortality: These additional studies should help answer questions about β-blocker mechanism of action, while adjusting for covariates (e
Beta-2 adrenergic receptors are cell-surface receptors clinically taken advantage of in the management of bronchospasm as in patients with bronchial asthma and chronic obstructive pulmonary disease

These include palpitations, tachycardia, tremulousness, anxiety, and heat intolerance
