Quinapril belongs to the class of medications called ACE inhibitors. It is used for the treatment of high blood pressure and congestive heart failure. It works by relaxing blood vessels and by making the heart pump more efficiently. Quinapril may be used in addition to diuretics (water pills) known as thiazide diuretics (e.g., hydrochlorothiazide) when one medication has not been found to control blood pressure satisfactorily.

Why is Accupril prescribed?
Accupril is used in the treatment of high blood pressure. It can be taken alone or in combination with a thiazide type of water pill such as HydroDIURIL. Accupril is in a family of drugs known as "ACE inhibitors." It works by preventing a chemical in your blood called angiotensin I from converting into a more potent form that increases salt and water retention in your body. Accupril also enhances blood flow throughout your blood vessels. Along with other drugs, Accupril is also prescribed in the treatment of congestive heart failure.
Most important fact about Accupril
You must take Accupril regularly for it to be effective. Since blood pressure declines gradually, it may be several weeks before you get the full benefit of Accupril; and you must continue taking it even if you are feeling well. Accupril does not cure high blood pressure; it merely keeps it under control.
How should you take Accupril?
You can take Accupril with or without meals.
Alcohol may increase the effect of Accupril, and could cause dizziness or fainting. Avoid alcoholic beverages until you have checked with your doctor.
Take Accupril exactly as prescribed, and see your doctor regularly to make sure the drug is working properly without unwanted side effects. Do not stop taking Accupril without first consulting your doctor.
If you miss a dose...
Take the forgotten dose as soon as you remember. However, if it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Never try to "catch up" by doubling the dose.
