What's the difference between selective and non selective beta blockers for glaucoma?

What's the difference between selective and non selective beta blockers for glaucoma?

Systemic effects: Beta blocker drugs are effective agents to lower the internal eye pressure in treating glaucoma. There is some systemic absorption and in sensitive individuals non-selective blockers can lower the maximum heart rate, cause lung spasms and elevate the blood sugar. Selective blockers have less tendency to do these but if you are taking these agents, report changes to your ophthalmologist. ...Read more

What is the difference between beta blockers and ARBs?

What is the difference between beta blockers and ARBs?

Difference: Beta blockers block beta receptors, ARBs or angiotensin receptor blockers block angiotensin receptors. Those are different receptors with different biochemical effects of their blockade. ...Read more

In child speak, what is the difference between alpha and beta blockers?

In child speak, what is the difference between alpha and beta blockers?

.: Alpha blocker - dilate smooth muscle - in artery so decrease blood pressure. Also decrease action of norepinephrine (which normally increases blood pressure). Beta blocker - work on heart and decrease heart rate, and decrease action of Epinephrine (which normally increases blood pressure). Simplest answer I can write. ...Read more

What's the difference between calcium channel blockers and beta blockers?

What's the difference between calcium channel blockers and beta blockers?

Name says it all: Calcium channel blockers block the channel that allows vascular tone to increase and lowers blood pressure. The beta blockers work on beta recetors on the vessels to lower pressure. The heart has both beta receptors and calcium channels. Therefore betablockers and some calcium channel blockers can slow the heart rate as well. ...Read more

Can people with hr in 30s 40s in sleep take beta blockers? And if they have low during day what is the difference?

Can people with hr in 30s 40s in sleep take beta blockers? And if they have low during day what is the difference?

Bradycardia: Slow heart rates that don't maintain adequate cardiac output can be a problem. Some people with sinus bradycardia can take beta blockers without slowing more. People who need higher heart rates to maintain cardiac output can have problems functioning if beta blockers slow their necessary rate too much. What happens depends on the individual and their responses. Caution is advisable. ...Read more

What is the difference between a beta blocker and a calcium channel blocker for arrhythmia?

What is the difference between a beta blocker and a calcium channel blocker for arrhythmia?

How they work.: Calcium channel blockers (ccb) affect calcium channels in the heart muscle cells. Beta blockers (bb) affect beta receptors in the conduction pathways of the heart. Each act to decrease heart rate and can also decrease blood pressure. Sometimes with ccb, the heart experiences an increase in heart rate when blood pressure decreases. There are different brands and kinds of both medications. ...Read more

Selective beta blockers instead of non selective for asthma patients? Or are both bad?

Selective beta blockers instead of non selective for asthma patients? Or are both bad?

Selective may be OK: Selective beta 1 blockers are are tolerated by most asthmatics at lower doses. Non-selective beta blockers are contra-indicated in asthmatics because they block the beta2 receptors in the airways, leasing to broncho-constriction. Even non-selective applied to the eyes (for glaucoma) can cause asthma attacks or poorer control. High doses of beta1 may rarely cause similar worsening of asthma. ...Read more

Why might epinephrine cause cardiac standstill in a patient on non-selective beta blockers?

Why might epinephrine cause cardiac standstill in a patient on non-selective beta blockers?

Theory: If you assume epi is alpha-beta stimulator and nonselective beta blocker blocks both types of beta, then pure alpha stimulation without beta stimulation to support it could theoretically cause the heart to crash. Not sure there is clinical evidence to support this however. ...Read more

Wat do beta blockers do?

Wat do beta blockers do?

Beta-blockers: Beta blockers is a class of drugs that affect beta-adrinergic receptors. There are at least two of those that beta-blockers block, known as beta-1 and beta-2. They are found in different body tissues and blocking beta-1 and beta-2 receptors exercises certain effect on the tissues where those are located. Beta-blockers are frequently used in people with high blood pressure, arrhythmia, heart issues. ...Read more

What do beta blockers do?

Beta blockers: Beta blockers block beta receptors. Beta receptors are molecular structures on certain cells which when beta agonists attach to them cause effects like increased heart rate and blood pressure. The beta blockers attach and the beta agonists can't hook up and cause the increase in heart rate and blood pressure ...Read more

How do beta-blockers work?

How do beta-blockers work?

See below: Debbie, Beta blockers act on the epinepherine (adrenaline) receptor. They block it, stopping the epi from attaching to it. The functional result is that they act to slow your heart rate and lower your blood pressure. They are excellent blood pressure medicines if you need them. Hope this helps! ...Read more

I have been prescribed beta blockers, what are these?

I have been prescribed beta blockers, what are these?

Receptor Blockers: Beta is short for beta adrenergic receptor and beta blockers inhibit these receptors that are stimulated primarily by epinephrine and norepinephrine, our "fight or flight" hormones. The importance in heart disease is that many disorders like a failing heart or heart attack are worsened by increased heart rate and demand on the heart. Beta blockers reduce this effect and help improve outcomes. ...Read more

Can I manage af by avoiding triggers without beta blockers?

Can I manage af by avoiding triggers without beta blockers?

Yes and no: Betablockers do not prevent atrial fib. It's rare to be able to identify a true trigger. Paroxysmal atrial fib occurs unpredictably. Caffeine and nicotine may make it worse. Bbs slow the pulse but don't prevent spells. Calcium channel blockers (eg verapamil and diltiazem) are good alternatives to bbs. An antiarhythmic (eg flecainide, sotalol, dolfetilide or amiodarone) can actually prevent af. ...Read more
