Which medication is indicated for the treatment of hypertension?

Inderal, which is a brand name for propranolol, is indicated for the treatment of hypertension. This medication belongs to a class known as beta-blockers, which work by blocking the effects of epinephrine (adrenaline) on the beta receptors in the heart and blood vessels. By doing so, it lowers heart rate, reduces the force of heart contractions, and helps to relax blood vessels, ultimately leading to a decrease in blood pressure.

The other medications listed do not have primary uses in treating hypertension. Zetia is primarily used to lower cholesterol, Symbicort is a combination inhaler used for asthma and chronic obstructive pulmonary disease (COPD), and Nystatin is an antifungal medication used to treat fungal infections. Thus, Inderal is clearly indicated for managing high blood pressure, making it the correct choice for this question.
