CARVEDILOL. Carvedilol (Coreg) is a novel agent with antagonist activity against alpha1, beta1 and beta2 receptors, as well as some antioxidant activity. It is the only beta blocker labeled by the U.S. Food and Drug Administration (FDA) for the treatment of heart failure.Dec 1, 2000
What is the first-line medication in case of congestive heart failure?
Loop diuretics should be used as first-line agents, with thiazides added for refractory fluid overload. Diuretic treatment should be combined with a low-salt diet,8 a β-blocker, and an ACE inhibitor. The practitioner should begin with oral furosemide, 20 to 40 mg once daily.
What is the drug of choice for congestive heart failure?
There are many different types of diuretic, but the most widely used for heart failure are furosemide (also called frusemide) and bumetanide.
When was Coreg invented?

Why are ACE inhibitors first-line for heart failure?
ACE inhibitors dilate the blood vessels to improve your blood flow. This helps decrease the amount of work the heart has to do. They also help block a substance in the blood called angiotensin that is made as a result of heart failure. Angiotensin is one of the most powerful blood vessel narrowers in the body.Oct 16, 2019
Why are beta blockers used in heart failure?
The use of beta blockers which may inhibit sympathetic activity, might reduce the risk of disease progression in heart failure, improve symptoms and increase survival.

When to use a blocker?
β-Blockers can be used in patients who have asymptomatic and mild bradycardia, particularly when the heart rate increases with exercise. The possibility of drug interactions that may lower heart rate (eg, digoxin and amiodarone) should also be considered.
How many people with HF have CAD?
In the United States, approximately 70% of patients with HF have CAD. 10,11 Hypertension is a major risk factor for HF, 11 particularly in blacks. An increasing number of HF patients have diabetes.
What happens after a myocardial insult?
After a myocardial insult — acute (eg, MI) or chronic (eg, HTN) — that results in LV dysfunction, there is an increased activity of the renin-angiotensin and sympathetic nervous systems. 1 Sympathetic nervous system activation may accelerate LV remodeling, worsen myocardial function, and lower the threshold for life-threatening arrhythmias. 1 Progression of CAD also may contribute to worsening of HF. 10
Does bisoprolol reduce mortality?
Carvedi lol, metoprolol CR/XL, and bisoprolol have been shown to reduce mortality and morbidity in HF. However, only carvedilol and metoprolol CR/XL are approved for HF in the United States, whereas bisoprolol is approved in several European countries. The Figure describes the initiation, titration steps, and target doses.
What are beta blockers used for?
In addition to their utility in the treatment of CHF, beta blockers are also often used to treat cardiac problems due to vascular disease, coronary artery disease, high blood pressure, and diabetes.
What is acute decompensated congestive heart failure?
This is referred to as decompensating, which simply refers to the fact that the previously working cardiovascular system has suddenly begun to fail.
What is heart failure?
Heart failure is a condition in which the heart is incapable of working effectively enough to supply the body with sufficient blood flow. This condition can have many causes, including heart attack, chronic high blood pressure, and damage or malformation of the heart or a heart valve. If the underlying problem causing the heart failure does not ...
How does beta blocker work?
Beta blockers work by blocking the activity of a hormone called epinephrine, or adrenalin. The medication causes a reduction in heart rate, and a reduction in the force of heartbeats. Both of these measures help reduce blood pressure. In addition, beta blockers help widen blood vessels, which helps improve freedom of movement ...
How do beta blockers improve survival?
In the treatment of patients with heart failure, beta blockers have been noted to improve survival rate by as much as 35%. In addition to their utility in the treatment of CHF, ...
What is decompensation in heart failure?
Decompensation occurs when the body is no longer able to compensate for the physical problems caused by heart failure. Congestive heart failure is a major public health issue, and a leading cause of hospitalization in people over the age of 65.
Can heart failure cause shortness of breath?
If the underlying problem causing the heart failure does not respond to treatment, then symptoms of heart failure can worsen over time. Possible symptoms include severe shortness of breath, swelling of the ankles, coughing, and an inability to exercise. Acute decompensated congestive heart failure is a condition in which chronic heart failure ...

Beta-adrenergic receptor blockers play an important role in the management of cardiovascular disease , including hypertension, ischemic heart disease and chronic heart failure. They differ, though, in beta-selectivity, vasodilation properties, and other ancillary features.
Which receptor blocker is responsible for vasodilator effect?
Blocks the alpha-1, beta-1 and beta-2 receptors and alpha-1 receptor blokade is responsible for the vasodilator effect. It has a partial agonist effect and is metabolised mainly by the liver.
Can beta blockers cause vasoconstriction?
Traditional beta blockers on the other hand may cause peripheral vasoconstriction and disturb the glucose utilisation in the periphery and reduces insulin sensitivity (7). Its distinctive features allow different applications and usage and there are several trials for various conditions.
Is D-nebivolol a beta-1 antagonist?
It is a mixture of D and L isomeres. D-nebivolol is a selective beta-1 antagonist while L-nebivolol is responsible for the nitric oxide dependent vasodilator effect. Its negative inotropic effect is lower than metoprolol and carvedilol and does not have any membrane stabilising or intrinsic sympathomimetic effects.
Is Nebivolol an antihypertensive?
Nebivolol as an antihypertensive agent was tested in 6376 patients in whom a significant reduction both in systolic and diastolic blood pressure has been achieved.

Evidence Supporting The Use of Β-Blockers in HF
- Background
The initial experience with β-blockers in HF was reported in 1975,16 and the first observations on survival were made in 1979.17 However, the first multicenter randomized trial was not published until 1993,18and it was 1997 before a β-blocker (carvedilol) was first approved for the treatmen… - Randomized Clinical Trials
The available randomized data overwhelming show that carvedilol, metoprolol CR/XL, and bisoprolol reduce morbidity and mortality in minimally, moderately, or severely symptomatic patients with HF (Table 2). It is noteworthy that β-blockers were used in addition to ACE inhibitor…

Clinical Management Issues
- Volume Overload
Incidence of adverse effects are listed in Table 3. β-blockers should not be initiated in patients with moderate to severe fluid retention. HF is a progressive disease, and it is likely that during its course, many patients will develop signs and symptoms related to fluid retention. The initial app… - Hypotension
Asymptomatic hypotension is common in patients with severe HF, and in itself it is not a contraindication to β-blocker therapy.6It is important to determine by obtaining supine and standing blood pressures that the hypotension is not caused by an inadequate preload related t…
Conclusion
- More than 5 years after the first approval of a β-blocker for the treatment of HF by the Food and Drug Administration, this life-saving therapy continues to be underutilized. Given the recommendation to use β-blockade in all HF patients without a contraindication, more effort is needed to improve the dissemination of the scientific, clinical, and practical aspects of β-blocke…
