HOW DO ACEI/DIURETIC COMBOS WORK?
Angiotensin-converting enzyme inhibitor/diuretic (ACEI/diuretic) combination drugs are used to treat high blood pressure. They work by relaxing blood vessels and removing excess water and salt from the body.
ACEIs work by inhibiting angiotensin-converting enzyme (ACE). This enzyme converts a signal protein in the body, angiotensin I to angiotensin II. Angiotensin II is a substance that narrows the blood vessels and contributes to salt and water retention in the body, leading to increased blood pressure. ACEIs block the action of angiotensin II and dilate the blood vessels, which in turn lowers the blood pressure.
Diuretics also known as water pills are drugs that cause diuresis (increase in the production of urine by the kidneys). The diuretic component present in this combination drug works on the ascending limb of the loop of Henle of nephrons in the kidneys and eliminates sodium, chloride, and water from the body as urine. This results in decreased blood pressure as the blood volume decreases.
