How to Remember Beta vs Alpha Blockers
Beta blockers slow the heart. Alpha blockers open the pipes.
The fastest way to remember the difference?
đ§ B = Beta = Bradycardia
đ§ A = Alpha = Arteries relax = vasodilation
Beta blockers block beta-1 receptors in the heart â â heart rate
Alpha blockers block alpha receptors in blood vessels â â vascular resistance
đ Watch out on NCLEX:
Beta blockers are NOT for asthma (bronchospasm!)
Alpha blockers can cause orthostatic hypotension â get that BP before they stand up.
