What is the therapeutic use of beta-blockers?
These drugs are often used to treat high blood pressure when other medications haven’t worked. 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.
What therapeutic class is propranolol?
Propranolol is in a class of medications called beta blockers. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure.
Are beta-blockers agonists or antagonists?
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.
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 is safest beta-blocker?
Cardioselective. 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.
What’s the difference between metoprolol and propranolol?
Inderal (Propranolol) Lowers blood pressure and controls heart rate. Lopressor (metoprolol tartrate) lowers high blood pressure, controls chest pain, and helps treat heart failure and heart attack. You need to take it with food and can’t miss a dose.
What are the most common beta blockers?
propranolol (generic Inderal® and Inderal LA® )
What is the safest beta blocker?
Beta blockers are generally safe to take. Side effects tend to be annoying, not life-threatening.
What is the most popular beta blocker?
Some examples of common beta blockers include: Sectral (acebutolol), Inderal (propranolol), Tenormin (atenolol), Zebeta (bisoprolol), Lopressor (metoprolol), Corgard (nadolol), Blocadren (timolol),
How dangerous are beta blockers?
Beta blockers generally aren’t used in people with asthma because of concerns that the medication may trigger severe asthma attacks. In people who have diabetes, beta blockers may block signs of low blood sugar, such as rapid heartbeat. It’s important to monitor your blood sugar regularly.
