What are BETA BLOCKERS? How do they work? | Bisoprolol, Atenolol, Carvedilol, Metoprolol

How do beta blockers work and what do they do to your body? Well, this video is for you! Here's the explainer with the what, how, why, side effects, history and pharmacology (two advanced sections in the 2nd half).

There are lots of beta-blockers out there and they're really good for heart conditions and high blood pressure. They can also be used for glaucoma.

Common ones include bisoprolol, atenolol, labetalol, carvedilol, metoprolol, propranolol, sotalol. You might also know them by their brand names: Tenormin, Cardicor, Emcor, Betaloc, Lopressor, Nebilet, Angilol and Inderal.

As always we go through things in simple terms and then for the hardcore nerds we're into the complex stuff.

You'll learn about how these drugs act on the beta adrenoreceptors in your body - that's where adrenaline, noradrenaline (or epinephrine and norepinephrine) bind.

It would make my day if you could also follow me on:

I’ve been on beta blockers for 11 years and I’ve been wondering why I never get the fight or flight thing. I just thought my brain was wonky but this explains it. Thank you

[harryandnatalia]

Another really useful video. I get asked these questions every day from patients, and explaining in a simplified way is so much easier 😊

[geordiebedlington]

Truly, another most excellent piece of work. It makes it very easy to understand!

[BlueInk]

Thank you. Great info delivered/presented in digestible format on all counts - just what my doctor ordered.!

[ncediledlamini]

I was on a large dose of Beta Blockers for 2 months, and I couldn't take it. I had to get off of them. I tapered in half and then in half again over the last month, and when I finally stopped them, I had 2 weeks of feeling like I was having a heart-attack. It was terrible. I hope they help some people, but the way I felt while taking them didn't work for

Me and everyone I know personally who's on bisoprolol have all started with tinnitus

[nenadcubric]

I feel calm and good on Propranolol or Atenolol but bad on Bisoprolol??

[BlaxJakx]

Have been in hospital for my crohns and colitis the past 8 weeks and my blood pressure along with heart rate over the past few months has been getting worse and worse and I’ve just been put on this drug today due to the results of the past 3 days of ECG results.
I’m only 31 (literally turned 31 last week). I’m not overweight and it’s come as a bit of a shock as like when you get anything wrong with your heart you assume it’s really really bad? My parents and family are visiting tomorrow and I know they will be asking what’s what and I don’t know if I want to tell them as they will worry and I don’t want them worrying.

So can a beta blocker for b1 receptors trigger high potassium levels?

[masala]

I’ve been put on beta blockers, fine so far in dealing with the palpitations after the Covid jabs but finding they give me very loose bowels.

[keysersoze]

I think its wiser to flight than fight a lion.
