Coreg

Definition

Coreg (Carvedilol) is a non-selective beta-adrenergic blocker used to treat heart failure and hypertension. It works by reducing the heart rate and relaxing blood vessels, improving blood flow and decreasing the workload on the heart.

5 Must Know Facts For Your Next Test

1. Coreg can reduce mortality in patients with chronic heart failure.
2. It blocks both beta-1 and beta-2 adrenergic receptors, as well as alpha-1 receptors.
3. Common side effects include dizziness, fatigue, hypotension, and bradycardia.
4. Coreg should be taken with food to slow its absorption and decrease the risk of orthostatic hypotension.
5. Patients with asthma or severe chronic obstructive pulmonary disease (COPD) should use Coreg cautiously due to its non-selective beta-blocking activity.
