Whats the difference between selective and non selective beta blockers for glaucoma?

Whats 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
