Study Notes
Beta-Adrenergic Blockers
Prototype drug
- Metoprolol is the prototype drug, marketed as Lopressor and Troprol XL.
Mechanism of Action
- Beta-adrenergic blockers block the cardiac action of the sympathetic nervous system.
- This blockade slows down the heart rate and blood pressure.
- As a result, the workload of the heart is reduced.
Primary Use
- Beta-adrenergic blockers are primarily used to treat conditions related to high heart rate and blood pressure.
