Which agents are primarily used to prevent and control high blood pressure?

The primary function of anti-hypertensive agents is to manage and lower high blood pressure, which is essential for preventing complications such as heart disease, stroke, and kidney damage. These medications work through various mechanisms, including vasodilation, reducing blood volume, and decreasing heart rate, to effectively control blood pressure levels.

In the context of the other options, antiseizure agents are designed to manage seizure disorders and do not play a role in blood pressure regulation. Antinausea agents are intended to alleviate nausea and vomiting, and their primary use is unrelated to controlling blood pressure. Antibiotics are used to treat bacterial infections and have no impact on blood pressure management. Therefore, the most appropriate choice for preventing and controlling high blood pressure is indeed anti-hypertensive agents.
