Which of the following is an antihypertensive medication?

Metoprolol is classified as an antihypertensive medication because it belongs to a group of drugs known as beta-blockers. These medications work by blocking the action of certain hormones, particularly epinephrine, which can help to lower blood pressure by causing the heart to beat more slowly and with less force. Additionally, metoprolol is commonly prescribed to treat conditions such as hypertension, angina, and heart failure.

The other medications mentioned are used for different purposes. Atorvastatin and Simvastatin are both statins, which are primarily utilized to lower cholesterol levels in the blood and reduce the risk of cardiovascular disease. Levothyroxine is a synthetic thyroid hormone used to treat hypothyroidism, and while it can have an effect on heart rate and blood pressure, it is not classified as an antihypertensive. Understanding the specific indications and classifications of these medications is crucial in the clinical management of conditions such as high blood pressure.
