    Effects of Drug Abuse

    Short-Term Effects

    • Dry hacking nonproductive cough may occur within few months of treatment; consider other causes of cough prior to discontinuation.
    • See "What Are Side Effects Associated with Using Accupril?"

    Long-Term Effects

    • See "What Are Side Effects Associated with Using Accupril?"

    Cautions

    • Excessive low blood pressure (hypotension) if concomitant diuretics, hypovolemia, hyponatremia
    • Discontinue STAT if pregnant (see Contraindications and Warnings)
    • Less effective in blacks
    • Renal impairment may occur
    • Cough may occur within the first few months
    • Cholestatic jaundice may occur
    • Use caution in severe aortic stenosis
    • Risk of high blood potassium (hyperkalemia), especially with renal impairment, diabetes mellitus, or those taking concomitant potassium-elevating drugs
    • Dual blockade of the renin angiotensin system with angiotensin receptor blockers (ARBs), angiotensin converting enzyme (ACE) inhibitors, or aliskiren associated with increased risk for hypotension, hyperkalemia, and renal function changes (including acute renal failure) compared to monotherapy
    • 25-30% decreased absorption with high-fat meal
    • ACE inhibition also causes increased bradykinin levels which putatively mediates angioedema
    • Skin swelling (angioedema) of the face, extremities, lips, tongue, glottis, and larynx has been reported in patients treated with angiotensin-converting enzyme inhibitors
    • If laryngeal stridor or angioedema of the face, tongue, or glottis occurs discontinue therapy and institute appropriate therapy immediately
    • Patients receiving coadministration of ACE inhibitor and mTOR (mammalian target of rapamycin) inhibitor (e.g. temsirolimus, sirolimus, everolimus) therapy may be at increased risk for angioedema
    • Intestinal angioedema has been reported in patients treated with ACE inhibitors
    • Dry hacking nonproductive cough may occur within few months of treatment; consider other causes of cough prior to discontinuation
    • Agranulocytosis, neutropenia, or leukopenia with myeloid hypoplasia reported with other ACE inhibitor; patients with renal impairment are at high risk; monitor complete blood count (CBC) with differential in these patients

    Pregnancy and Lactation

    • Use quinapril with caution during the first trimester of pregnancy if benefits outweigh risks. Animal studies show risk and human studies are not available or neither animal nor human studies were done. Use quinapril during the second and third trimesters of pregnancy only in LIFE-THREATENING emergencies when no safer drug is available. There is positive evidence of human fetal risk.
    • Discontinue quinapril as soon as pregnancy is detected. During the second and third trimesters of pregnancy, drugs that act directly on the renin-angiotensin have been associated with fetal injury that includes low blood pressure (hypotension), neonatal skull hypoplasia, anuria, reversible or irreversible renal failure, and death.
    • Quinapril is excreted in breast milk. Use caution if breastfeeding.
