Question: 1 / 400

Identify a common therapeutic use for beta-blockers.

To increase heart rate

To manage hypertension and heart failure

Beta-blockers are commonly used in clinical practice for managing hypertension and heart failure. They work by blocking the effects of adrenaline on the beta-adrenergic receptors in the heart, leading to a decrease in heart rate and contractility. This action helps to lower blood pressure and reduce the workload on the heart, making beta-blockers effective in treating conditions like hypertension.

In the context of heart failure, beta-blockers can improve the heart's efficiency and help it pump blood more effectively. They also assist in preventing heart rhythm irregularities and reducing the risk of heart-related events. The therapeutic use of beta-blockers in these conditions is well-supported by evidence and guidelines in cardiovascular medicine.
