Beta blockers are contraindicated in vasospastic angina because they can potentially exacerbate vasospasm. These medications decrease heart rate and contractility, which can lead to unopposed alpha-adrenergic receptor stimulation in the coronary arteries, causing them to constrict further. This can worsen ischemia and provoke anginal episodes. Instead, calcium channel blockers or long-acting nitrates are typically preferred to help relieve vascular tension and prevent spasms.

Why beta-blockers are contraindicated in vasospastic angina?
Beta-blockers are contraindicated in vasospastic angina because they can exacerbate vasospasm by blocking beta-2 adrenergic receptors, which normally mediate vasodilation. In patients with vasospastic angina, the primary issue is inappropriate vasoconstriction, and using beta-blockers may worsen this condition by limiting the body's ability to dilate blood vessels during episodes of angina. Instead, calcium channel blockers or nitrates are preferred as they promote vasodilation and help alleviate symptoms.
What Cardiac and antihypertensives are contraindicated in people with Diabetes?
beta blockers
What beta blockers to treat angina and high blood pressure may not be effective when taking calcium channel blockers?
Beta-blockers, such as atenolol (Tenormin), propranolol (Inderal), and metoprolol (Lopressor), used to treat high blood pressure, angina, and other conditions.
Are there any drugs that treat both angina and hypertension?
One such drug is NORVASC® (amlodipine besylate), which treats both angina and hypertension. Another drug that does the same is Beta-blockers.
What is another name for beta blockers?
Beta blockers, also known as beta-adrenergic blockers
How severe is angina and how can it be relieved?
Agnina can be severe, and extremely painful, and in some cases leads to heart attacks. Aspirin in low doses, Glyceryl trinitrate, beta blockers, calcium channel blockers and potassium channel activators are all treatments for angina. http://www.netdoctor.co.uk/diseases/facts/angina.htm
How do doctors treat angina?
Anti anginal medications include nitrates such as nitroglycerin and beta adrenergic receptor blockers (beta blockers). Nitrates work by causing dilation of the arteries of the heart so more blood can flow through to bring oxygen to the heart. B blockers work by decreasing the work-load of your heart and decreasing the amount of oxygen required by your heart to do the same amount of work
Why beta blockers are contraindicated in pregnancy?
While beta blockers can sometimes be taken safely with a doctor's guidance by pregnant women, they do carry a risk of harm to the fetus. They lower the blood pressure and slow the heart rate, and may cause low blood sugar. All of this has the potential to affect the fetus.
Identify the forms of nitroglycerin that are helpful in preventing angina?
Sublingual tablets and sprays are forms of nitroglycerin that are commonly used to prevent angina attacks. These forms work quickly to dilate blood vessels, improving blood flow to the heart and reducing chest pain.
Why do athletes take beta blockers?
Beta-blockers are drugs that are prescribed to treat several different types of conditions, including hypertension, angina, some abnormal heart rhythms, heart attack, anxiety, migraine, glaucoma, and overactive thyroid symptoms; someone who is suffering from any of those symptoms might have to take beta-blockers.
Are beta blockers steroid?
No they are not.
Why beta blockers are given first in pheochromocytoma?
They are not. Alpha blockers are given first because beta blockers without prior alpha blockade can cause a hypertensive crisis.
