Since bystoilc is selective beta blocker(works on the heart only), can it still lower ocular pressure in glaucoma or does non selective bb is better ?

Since bystoilc is selective beta blocker(works on the heart only), can it still  lower ocular pressure in glaucoma or does non selective bb is better ?

Yes: Systemic beta blockers(bb) can lower iop, but not as effectively as when a topical ophthalmic preparation is used. Selective vs non- selective bbs very in their potency at blocking beta receptors in the eye & heart. Non-selective bbs block both types of receptors(b1 & b2) and lower iop more than selective type( b1). The later type is thought to be a safer medication with less pulmonary side effect. ...Read more

What is the definition or description of: beta-blocker?

What is the definition or description of: beta-blocker?

Anti-adrenaline: A beta blocker is a medication which prevents adrenaline-like compounds from connecting to the "beta adrenergic receptors" in the body. Beta-1 receptors affect heart squeeze, relaxation and rhythm and are usually the primary target. Medicines like metoprolol and atenolol work only on this receptor. Other "nonselective" beta blockers block beta-1 and beta-2, with or without other effects as well. ...Read more

Is Excedrin extra strenght a beta blocker?

No, its a different : Excedrin extra strength is acetaminophen, Aspirin and caffeine. It works in a completely different system, does not affect beta receptors, and does not work on blood pressure or heart rate. The caffeine may mildly speed up your hear rate, but otherwise they are completely unrelated. ...Read more

If am on a beta blocker, why can I feel a strong heartbeat?

Heart Beat: Beta blockers (ex. Lopressor, metoprolol, inderal, coreg, bystolic (nebivolol) etc..) have an inherent tendency to slow down and lower your heart rate. It's a divine intervention that one should not feel his/her own heart beat or breathing - if you feel them both - it clearly indicates that something is wrong - and need medical attention. It is normal not feel your heart beat. ...Read more
