Final answer:
Beta-blocker drugs actually lower blood pressure by blocking the action of adrenaline on beta-receptors in the body.
Step-by-step explanation:
The statement is False.
Beta-blocker drugs actually lower blood pressure by blocking the action of adrenaline (also known as epinephrine) on beta-receptors in the body. Adrenaline is a hormone that normally causes an increase in heart rate and constriction of blood vessels, which can result in higher blood pressure. By blocking the beta-receptors, beta-blocker drugs reduce the effects of adrenaline, leading to a decrease in heart rate and relaxation of blood vessels, ultimately resulting in lower blood pressure.
For example, if someone has hypertension (high blood pressure), their healthcare provider might prescribe a beta-blocker drug like metoprolol or propranolol to help lower their blood pressure and improve their cardiovascular health.
