Beta-blockers are a class of medicines commonly used to treat a wide range of problems involving your heart and your circulatory system. They also are sometimes used to treat conditions related to your brain and nervous system.
Your body uses a chemical signaling system to control certain processes and functions. This uses specific sites on the surface of your cells, called receptors, where certain chemicals — called neurotransmitters — can latch on. Receptors work similarly to locks. If a chemical with the right structure latches onto a receptor, it works like a key and ...
Beta receptors come in three different sub-types and have different functions depending on their location.
Because beta-receptors are found in several locations throughout the body, beta-blockers can treat a wide range of problems and conditions. Beta-blockers are mainly used to treat heart and circulatory conditions, including the following: 1. Aortic dissection. 2. Arrhythmias. 3. Chest pain (angina). 4. Coronary artery disease. 5. Heart attack. 6. He...
Beta-blockers are some of the most commonly prescribed medications in the United States, with approximately 30 million adults using a beta-blocker.
Beta blockers are competitive antagonists that block the receptor sites for the endogenous catecholamines epinephrine (adrenaline) and norepinephrine (noradrenaline) on adrenergic beta receptors, of the sympathetic nervous system, which mediates the fight-or-flight response.
Nov 16, 2021 · Beta-blockers are medications that block the effects of stress hormones on the heart. They’re used to treat high blood pressure, irregular heartbeat, heart attack, and other conditions. Learn about the different types, side effects, interactions, and how to stop taking them.
- Metoprolol. Metoprolol is a selective beta blocker. Selective beta blockers like metoprolol are often called “cardioselective” because they mainly act on the heart.
- Carvedilol. Carvedilol is a non-selective beta blocker. It also blocks alpha-1 receptors. Blocking alpha-1 receptors helps widen your blood vessels, which can help lower blood pressure.
- Atenolol. Atenolol (Tenormin) is a selective beta blocker. It’s FDA-approved to treat high blood pressure and angina. It can also lower your risk of death after a heart attack.
- Propranolol. Propranolol is a non-selective beta blocker. It’s FDA approved to treat several heart conditions including angina, hypertension, and atrial fibrillation.
Aug 4, 2022 · Beta blockers are drugs that block the effects of adrenaline and norepinephrine on beta receptors in the body. They are used for various conditions such as high blood pressure, heart failure, and glaucoma, but they may also cause serious side effects and interactions.
Aug 22, 2023 · Beta-blockers, as a class of drugs, are primarily used to treat cardiovascular diseases and other conditions. [1] Beta receptors exist in three distinct forms: beta-1 (B1), beta-2 (B2), and beta-3 (B3). Beta-1 receptors located primarily in the heart mediate cardiac activity.
