Zebeta

Definition

Zebeta, also known as bisoprolol, is a beta-adrenergic blocker used primarily to manage hypertension and heart failure. It works by reducing the heart rate and the heart's workload.

5 Must Know Facts For Your Next Test

1. Zebeta selectively blocks beta-1 adrenergic receptors in the heart, which decreases heart rate and cardiac output.
2. It is often prescribed to improve survival rates in patients with chronic heart failure.
3. Common side effects of Zebeta include fatigue, dizziness, and bradycardia (slow heart rate).
4. Zebeta should be used cautiously in patients with asthma or other bronchospastic conditions because it can cause bronchoconstriction.
5. Abrupt discontinuation of Zebeta can lead to rebound hypertension and exacerbation of angina.
