Information on Tablets A-Z
Generic name: Quinapril hydrochloride
Why is this drug 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 this drug: 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 this medication: 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 this drug without first consulting your doctor. --If you miss a dose... Take the forgotten dose as soon as you remember.
