Atenolol belongs to a class of drugs known as beta blockers. It works by blocking the action of certain natural chemicals in your body, such as epinephrine, on the heart and blood vessels. This effect lowers the heart rate, blood pressure, and strain on the heart.
Is atenolol a Beta 1 or 2 blocker?
Atenolol is a second-generation beta-1-selective adrenergic antagonist indicated in treating hypertension, angina pectoris, and acute myocardial infarction.
Is atenolol a selective beta-blocker?
The cardio-selective beta-blockers include atenolol, betaxolol, bisoprolol, esmolol, acebutolol, metoprolol, and nebivolol.
Is atenolol an antiarrhythmic drug?
Atenolol is used primarily as an antiarrhythmic or for other cardiovascular conditions in which it is needed to slow the sinus rate. In cats, this drug is commonly used to treat heart disease from cardiomyopathy or hyperthyroidism, but it should not be used as monotherapy to treat primary hypertension.
Is atenolol an ACE inhibitor or ARB?
Cozaar is an angiotensin receptor blocker (ARB) and atenolol is a beta-blocker.
Which side effect is most often caused by atenolol?
General. The more commonly reported side effects associated with this drug are hypotension, tiredness, and dizziness.
Is atenolol a beta-2 antagonist?
Atenolol is a “cardioselective” beta-adrenoceptor antagonist. It inhibits selectively beta-1 receptors with a lower affinity for beta-2 receptor subtype.
What are the top 5 beta-blockers?
Which beta blocker is most effective?
Atenolol (Tenormin)Betaxolol (Betoptic eye drops, Kerlone tablets)Bisoprolol (Zebeta)Esmolol (Brevibloc injection)Metoprolol tartrate (Lopressor)Metoprolol succinate (Toprol XL)Nebivolol (Bystolic)
What is the safest beta-blocker?
A number of beta blockers, including atenolol (Tenormin) and metoprolol (Toprol, Lopressor), were designed to block only beta-1 receptors in heart cells. Since they don’t affect beta-2 receptors in blood vessels and the lungs, cardioselective beta blockers are safer for people with lung disorders.
Why is atenolol preferred over metoprolol?
by Drugs.com
Atenolol is water soluble. Metoprolol is lipid soluble so is more likely to produce sleep disturbances and nightmares because it can cross the blood brain barrier. 2. Atenolol has a longer half life and can be taken once a day while Metoprolol needs to be taken twice daily.
Why is atenolol preferred over propranolol?
Inderal (Propranolol) Lowers blood pressure and controls heart rate. Tenormin (atenolol) is good for controlling chest pain and treating a heart attack. It has fewer side effects than other beta blockers.
What is the difference between selective and non selective beta-blockers?
The non-selective β-blockers offer α-blockade resulting in vasodilation and lower peripheral resistance without changes in cardiac output [27, 37, 38]. In addition, carvedilol reduces cardiac adrenergic activity while β-1 selective agents increase sensitivity to adrenergic activity [11].
What are the 4 classes of antiarrhythmic drugs?
Antiarrhythmic drug classes:
Class I – Sodium-channel blockers.Class II – Beta-blockers.Class III – Potassium-channel blockers.Class IV – Calcium-channel blockers.Miscellaneous – adenosine. – electrolyte supplement (magnesium and potassium salts) – digitalis compounds (cardiac glycosides)
Is atenolol used for tachycardia?
Abstract. Propranolol, a first-generation nonselective beta-adrenoceptor blocking agent, is commonly used to treat pediatric arrhythmias. Atenolol, relatively long-acting, cardioselective beta-adrenoceptor blocking agent, has been successfully used in adults with supraventricular tachycardia (SVT).
Does atenolol lower systolic or diastolic?
The most important findings were that (i) atenolol decreased systolic BP maximum values achieved during dynamic resistance exercise, (ii) atenolol also blunted the increase in systolic BP during the first set of dynamic resistance exercises of different intensities and (iii) atenolol decreased diastolic BP and
What is the difference between ACE inhibitors and angiotensin receptor blockers?
ACE inhibitors lower blood pressure by preventing the production of angiotensin II, a substance that narrows the blood vessels, while ARBs reduce the action of angiotensin II to prevent blood vessel constriction.
What is difference between beta-blocker and ACE inhibitor?
Beta-blockers treat many of the same conditions as ACE inhibitors, including high blood pressure, chronic heart failure, and stroke. Both types of medications also prevent migraines. Unlike ACE inhibitors, however, beta-blockers can help relieve angina (chest pain).
What is the difference between an ARB and a beta-blocker?
Like beta-blockers, ARBs are also blood pressure medications, but they lower blood pressure in a different way. ARBs block the action of a different hormone called angiotensin II (Burnier, 2001).
