Which beta-blockers are used in hypertension?
Beta-blockers include:
- Acebutolol (Sectral)
- Atenolol (Tenormin)
- Betaxolol (Kerlone)
- Bisoprolol (Zebeta, Ziac)
- Carteolol (Cartrol)
- Carvedilol (Coreg)
- Labetalol (Normodyne, Trandate)
- Metoprolol (Lopressor, Toprol-XL)
How do beta-blockers work for hypertension?
Beta blockers, also known as beta-adrenergic blocking agents, are medications that reduce blood pressure. Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. Beta blockers cause the heart to beat more slowly and with less force, which lowers blood pressure.
Why are beta-blockers contraindicated in hypertension?
In summary, beta-blockers are effective in preventing cardiovascular disease but are no longer suitable for routine initial treatment of hypertension because their cardiovascular protection and metabolic effects are worse than those of other antihypertensive drugs.
What are the three types of beta-blocker?
labetalol (also called Trandate) metoprolol (also called Betaloc or Lopresor) propranolol (also called Inderal or Angilol)
When are beta blockers first line?
National and international guidelines still recommend β-blockers (BBs) as first-line agents in uncomplicated prevention of hypertension. However, it has been shown that BBs reduce blood pressure less than other drugs, specifically with regard to central aortic pressure.
How much do beta blockers lower BP?
On average, beta‐1 blockers lowered BP by ‐10 points of systolic and ‐8 points of diastolic pressure in people with mild to moderate high blood pressure.
What are side effects of beta-blockers?
Common side effects of all beta blockers include:
- Slow heart rate (bradycardia).
- Low blood pressure (hypotension).
- Irregular heart rhythms (arrhythmias).
- Fatigue.
- Dizziness.
- Nausea.
- Insomnia, sleep changes and nightmares.
- Dry mouth or eyes.
Is beta-blocker first line hypertension?
Abstract. National and international guidelines still recommend β-blockers (BBs) as first-line agents in uncomplicated prevention of hypertension. However, it has been shown that BBs reduce blood pressure less than other drugs, specifically with regard to central aortic pressure.
What are the risks of taking beta-blockers?
The most common side effects of beta-blockers are:
- Fatigue and dizziness. Beta-blockers slow down your heart rate.
- Poor circulation. Your heart beats more slowly when you take beta-blockers.
- Gastrointestinal symptoms. These include upset stomach, nausea, and diarrhea or constipation.
- Sexual dysfunction.
- Weight gain.
What are the contraindications of beta-blockers?
Traditional contraindications to beta-blockers are peripheral vascular diseases, diabetes mellitus, chronic obstructive pulmonary disease (COPD) and asthma.
What are the contraindications of beta blockers?
Is there evidence for beta‐blocker therapy in hypertension?
Proper understanding of the evidence for beta‐blocker therapy in hypertension requires a regularly updated systematic, comprehensive, and appropriate analysis of all currently available data.
How do beta blockers work to lower blood pressure?
Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. When you take beta blockers, your heart beats more slowly and with less force, thereby reducing blood pressure. Beta blockers also help blood vessels open up to improve blood flow.
What are beta‐blockers?
Beta‐blockers refer to a mixed group of drugs with diverse pharmacodynamic and pharmacokinetic properties. They have shown long‐term beneficial effects on mortality and cardiovascular disease (CVD) when used in people with heart failure or acute myocardial infarction.
Are beta‐blockers or diuretics in hypertension diabetogenic?
