Podcast Transcription

Alright, so this next memory device is for beta blockers. So, beta blockers are an extremely common cardiac med. And, there’s beta 1, beta 2, and actually there’s also a beta 3. But we’re just gonna talk about beta 1 and beta 2 adrenergic receptors. So, beta 1 adrenergic receptors are mostly found in the heart. While beta 2 adrenergic receptors are found in the lungs, GI tract, vascular smooth muscles, skeletal muscle and liver. So, your beta 1 blockers act primarily on the heart and your beta 2 blockers act primarily on the lungs. And it’s really important to remember which ones do which because some beta blockers medications are selective and about which beta they block. Or, they’re non-selective and will block all of them. So, beta 1, heart, and beta 2 is the lungs. So, a really easy way to remember that is you have 1 heart, so beta 1, and you have 2 lungs, so beta 2 with your lungs. It’s super easy to remember and hopefully you’ll never forget it with that one. It’s really important because there are, let’s say, you need a patient that needs a beta blocker, but maybe they have asthma. So, if you’re giving them something that blocks everything, including, you know, the lungs, that could really affect the asthma and make it worst. So, things can be contraindicated like if there a nonselective beta blockers. So, it’s really important to remember what you’re blocking and which one. So, beta 1, 1 heart. Beta 2, 2 lungs.
