Name a common medication used to treat hypertension.

Amlodipine is a commonly prescribed medication for the treatment of hypertension, also known as high blood pressure. It belongs to a class of drugs called calcium channel blockers, which work by relaxing the blood vessels and improving blood flow. This action helps to lower blood pressure, making it an effective choice for managing hypertension.

In contrast, Metformin is primarily used to treat type 2 diabetes by improving insulin sensitivity. Atorvastatin is a statin used to lower cholesterol levels, reducing the risk of heart disease but not directly addressing blood pressure. Omeprazole is a proton pump inhibitor used to treat conditions like gastroesophageal reflux disease (GERD) and does not play a role in blood pressure management. Thus, Amlodipine stands out as the appropriate medication for addressing hypertension.
