Which medication is part of a combination treatment for hypertension?

Lisinopril with Hydrochlorothiazide is a common combination treatment for hypertension. Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor, which works by relaxing blood vessels to lower blood pressure. Hydrochlorothiazide is a thiazide diuretic that helps to eliminate excess fluid and reduce blood volume, further aiding in the decrease of blood pressure. The use of these two medications together is effective because they target different mechanisms of blood pressure regulation, leading to enhanced control of hypertension compared to using either medication alone.

In contrast, prednisone is a corticosteroid used primarily for its anti-inflammatory and immunosuppressive properties, tiotropium bromide is a medication for managing chronic obstructive pulmonary disease (COPD) rather than hypertension, and morphine sulfate is an opioid analgesic used for pain management. None of these medications are indicated for the treatment of hypertension.
