Study Notes
- Non-selective adrenergic antagonists competitively block norepinephrine effects at alpha- and beta-receptors in the SNS.
- Medications include amiodarone, carvedilol, and labetalol.
- These antagonists lower blood pressure, slow pulse, increase renal perfusion, and decrease renin levels.
- They treat hypertension, heart failure, and arrhythmias.
- Contraindications include bradycardia, heart blocks, shock, heart failure, diabetes, bronchospasm, and asthma.
- Adverse effects include dizziness, bradycardia, hypotension, dyspnea, N/V, blurry vision, and fatigue.
- Drug interactions occur with volatile anesthetics, some diabetic agents, verapamil or diltiazem, and QT prolonging medications.
