Final answer:
Option b) provides the correct list of beta-blockers: Atenolol, Metoprolol, Propranolol, Carvedilol, Labetalol, Nadolol, Timolol, and Sotalol. These medications block beta-receptors to reduce heart rate and blood pressure and are used to treat hypertension and other heart-related conditions.
Step-by-step explanation:
The correct answer to the question regarding examples of beta-blockers (antihypertensives) is option b) Atenolol, Metoprolol, Propranolol, Carvedilol, Labetalol, Nadolol, Timolol, Sotalol. These medications are known as sympatholytic drugs or \u03b2-blockers, and they are primarily used to treat cardiovascular diseases. They work by blocking the beta-receptors associated with vasoconstriction and cardioacceleration, thereby allowing blood vessels to dilate and preventing the heart rate from increasing. This action improves cardiac function, especially in patients with congestive heart failure or those who have suffered a heart attack.
Beta-1 receptors, like those that noradrenaline (NE) binds to, are specifically targeted by certain beta-blockers. By blocking these receptors, beta-blockers can slow the heart rate (HR) and are a possible treatment option for hypertension. However, it is important to note that overprescription of beta-blockers may lead to bradycardia or even heart stoppage.
