quinapril, Accupril (cont.)

Pharmacy Author:
Medical and Pharmacy Editor:

Combining quinapril or other ACE inhibitors with non-steroidal anti-inflammatory drugs (NSAIDs) in patients who are elderly, volume-depleted (including those on diuretic therapy), or with poor kidney function may result in reduced kidney function, including kidney failure. These effects usually are reversible.

There have been reports of increased lithium (Eskalith, Lithobid) levels when lithium is used in combination with ACE inhibitors. The reason for this interaction is not known.

Nitritoid reactions (symptoms include facial flushing, nausea, vomiting and hypotension) may occur when injectable gold (sodium aurothiomalate), used in the treatment of rheumatoid arthritis, is combined with ACE inhibitors, including quinapril.

Quinapril should not be combined with aliskiren (Tekturna) because the combination of both drugs increases blockade of angiotensin leading to low blood pressure, increased blood potassium, and possible kidney damage.

PREGNANCY: Angiotensin converting enzyme inhibitors, including quinapril, are very harmful to the fetus and, therefore, should not be used during pregnancy.

NURSING MOTHERS: Quinapril is secreted into breast milk. Because of the risk of harm to the infant, quinapril should be used with caution during breastfeeding.

SIDE EFFECTS: Quinapril is generally well tolerated, and side effects are usually mild and transient. A dry, persistent cough has been reported with the use of quinapril and other ACE inhibitors. Coughing resolves after discontinuing the medication. Other side effects include abdominal pain, constipation, diarrhea, rash, dizziness, fatigue, headache, loss of taste, loss of appetite, nausea, vomiting, fainting and numbness or tingling in the hands or feet.

Quinapril and other ACE inhibitors may also cause kidney failure and increased levels of potassium in the blood. The most serious but very rare side effects are liver failure and angioedema (swelling of lips and throat).
