How Does Quinaretic Work?
Quinaretic is a combination of two medicines --
Accupril® (
quinapril hydrochloride) and
hydrochlorothiazide. Accupril is part of a class of drugs called angiotensin-converting enzyme inhibitors, or ACE inhibitors for short. Accupril helps to block the angiotensin-converting enzyme, which is normally part of a reaction in the body that causes the blood vessels to narrow (constrict). By blocking this enzyme, Accupril causes blood vessels to relax.
Hydrochlorothiazide (HCT for short) is a diuretic (a type of drug commonly referred to as a "water pill"). It works by increasing the amount of salt and water that the kidneys remove from the blood. This extra salt and water is passed out through the urine. By increasing the amount of water removed from the blood, hydrochlorothiazide causes a decrease in blood volume.
Because of the effects of both Accupril and hydrochlorothiazide, Quinaretic can
lower blood pressure. As a result of its combined effects, Quinaretic causes a greater drop in
blood pressure than when either medicine is used alone.
