🔝 Beta-blockers are one of the top 200 drugs prescribed as they are indicated for many different cardiovascular diseases such as hypertension, angina, atrial fibrillation/flutter, and heart failure with reduced ejection fraction. ⁠⠀
⁠⠀
⭐Generally, there are two types of beta-adrenergic receptors, beta-1 and beta-2 receptors.⁠⠀
⁠⠀
-Non-selective beta-blockers block both beta-1 (β1) and beta-2 (β2) adrenoceptors. ⁠⠀
⁠⠀
-Cardioselective beta-blockers are relatively selective for β1 adrenoceptors (remember you have 1 heart) and tend to be favored in patients with diabetes or COPD/asthma. ⁠⠀
⁠⠀
-Some beta-blockers also cause vasodilation through blockade of vascular alpha receptors making them great for use in hypertension.⁠⠀
⁠⠀
🧠 Use the mnemonic – Be (β1) selective about your MAN BABE to help you remember the beta-blockers that are cardioselective. ⁠⠀
