Final answer:
Hypertension can be treated with sympathetic beta 1-receptor antagonists, also recognized as β-blockers, which include medications like metoprolol that block β1-receptors leading to dilation of blood vessels and reduced heart rate.
Step-by-step explanation:
Hypertension can indeed be treated with sympathetic beta 1-receptor antagonists, commonly known as β-blockers. These medications, like metoprolol, work by blocking the β1-receptors, which are associated with vasoconstriction and cardioacceleration. When these receptors are blocked, blood vessels can dilate and the heart rate is kept from increasing, thus lowering blood pressure and improving cardiac function in patients with conditions like congestive heart failure or those who have suffered a heart attack.
However, it is important to note that overprescription of these drugs may lead to bradycardia or even heart stoppage. Therefore, they must be prescribed and monitored carefully by healthcare professionals. Other β-blockers, such as propranolol, non-selectively block all β-receptors, affecting both the β1 and β2 subtypes and have a broader range of effects.
