Quinapril and hydrochlorothiazide combination is a prescription-only product which consists of two antihypertensive agents used in patients with high blood pressure (hypertension).
Unchecked hypertension for a prolonged time causes “extra” workload on the heart and blood vessels, resulting in damages to the blood vessels of the brain, heart, and kidneys. Over time, hypertension can lead to a stroke, heart failure, or kidney failure.
Quinapril is an angiotensin-converting enzyme (ACE) inhibitor that works by inhibiting the formation of blood vessel constricting chemicals in the body whereas hydrochlorothiazide is a diuretic (water pill) that works by increasing the rate of urine formation.
Both these actions have combined effect in reducing the blood pressure. It is available in tablet form.
