Name:
-olol: beta blocker
Lopressor: Low pressure
Receptors:
Blocks Beta1 selectively
Use:
HTN ---- by blocking catecholamine-induced increases => reducing heart rate, blood pressure, and contractile force => reduce HTN
Tachycardia----by blocking catecholamine-induced increases in heart rate => reduces tachy
SVT ---- beta-blocker => inhibits adrenergic activation of cardiac pacemaker potentials => slows conduction thru AV node => depresses sinus node automaticity => suppresses AV nodal conduction => SVT responds well to beta-blockers (1)
Mnemonics:
Metoprolol: Me top pro olol: top = SVT & beta1 selective, pro = tachy & hyper

| Me-top-pro-olol => me on top to help you with your SVT, tachy & hyper. I'm female = beta but I'm #1 => beta 1 |
