Competitively inhibits angiotensin-converting enzyme; prevents angiotensin I conversion to angiotensin II, a potent vasoconstrictor that also stimulates aldosterone secretion. Results in decrease in sodium and fluid retention, decrease in BP, and increase in diuresis.
T max is about 7 h.
Does not appear to be bound to other serum proteins.
Does not undergo metabolism.
The t ½ is 12 h. Excreted via the kidney; excreted unchanged entirely in the urine. Lisinopril can be removed by hemodialysis.
Special PopulationsRenal Function Impairment
Decreased elimination when glomerular filtration rate is 30 mL/min or less.Race
Black patients with hypertension had a smaller response to monotherapy of ACE inhibitor.CHF (New York Heart Association class II through IV)
Bioavailability decreases about 16% and Vd is slightly smaller.
Indications and Usage
Treatment of hypertension; treatment of heart failure not responding to diuretics and digitalis; treatment of acute MI within 24 h in hemodynamically stable patients.
Hypersensitivity to ACE inhibitors; hereditary or idiopathic angioedema.
Dosage and AdministrationCHF
Adults Initial dose
PO 5 mg every day with diuretics and digitalis; reduce concomitant diuretic dose, if possible, to minimize hypovolemia.Dose adjustment for hyponatremia (serum sodium less than 130 mEq/L) or moderate to severe renal function impairment (CrCl 30 mL/min or less or serum creatinine greater than 3 mg/dL)
PO Start with 2.5 mg once daily.Usual dose
PO 5 to 40 mg once daily.Hypertension
10 mg once daily. If a diuretic is coadministered, start with lisinopril 5 mg (under medical supervision) for at least 2 h and until BP has stabilized for at least 1 additional h.Maintenance
20 to 40 mg/day; may add diuretic if needed and decrease lisinopril dose.Renal function impairment Moderate to severe function impairment (CrCl 10 mL/min or more to 30 mL/min or less)
5 mg/day as initial dose.Dialysis (CrCl less than 10 mL/min)
2.5 mg/day as initial dose.Children (6 yr of age and older)
PO Start with 0.07 mg/kg every day (up to 5 mg). Adjust dose according to BP response. Doses above 0.61 mg/kg (or in excess of 40 mg) have not been studied. Not recommended in children with glomerular filtration rate less than 30 mL/min per 1.73 m 2 .MI
Adults Initial dose
PO 5 mg, then 5 mg after 24 h, then 10 mg after 48 h.Dose adjustment
PO In patients with low systolic BP (120 mm Hg or less) or when treatment is started during the first 3 days after infarct, administer 2.5 mg. If hypotension occurs (systolic BP 100 mm Hg or less) a daily maintenance dose of 5 mg may be given with temporary reductions to 2.5 mg if needed. If prolonged hypotension occurs (systolic BP less than 90 mm Hg for more than 1 h), discontinue treatment.Maintenance
PO 10 mg/day for 6 wk. Patients should receive, as appropriate, the standard recommended treatments, such as thrombolytics, aspirin, and beta-blockers.Renal function impairment (CrCl exceeding 2 mg/dL)
Use with caution.
- Give prescribed dose without regard to meals. Administer with food if GI upset occurs.
- Preparation of suspension: Add 10 mL of purified water to a polyethylene terephthalate bottle containing ten 20 mg tablets of lisinopril and shake for at least 1 minute. Add 30 mL of Bacitra diluent and 160 mL of OraSweet SF and shake gently for several seconds.
Store tablets at 68° to 77°F. Protect from moisture, freezing, and excessive heat.Suspension
Store suspension at controlled room temperature (below 77°F). Discard any unused suspension after 28 days.
Lisinopril bioavailability may be decreased. Separate administration times by 1 to 2 h.Antidiabetic agents
Risk of hypoglycemia may be increased.Capsaicin
Cough may be exacerbated.Digoxin
May increase or decrease plasma digoxin levels.Diuretics
Excessive decrease in blood pressure may occur.Gold therapy (eg, aurothiomalate)
Nitritoid reactions, including facial flushing, nausea, vomiting, and hypotension, may occur.Indomethacin, salicylates (eg, aspirin)
Reduced hypotensive effects, especially in low-renin or volume-dependent hypertensive patients.Lithium
Increased lithium levels and symptoms of lithium toxicity.NSAIDs
Increased risk of renal function impairment.Phenothiazines
May increase pharmacological effect of lisinopril.Potassium-sparing diuretics, potassium preparations
May increase serum potassium levels.
Laboratory Test Interactions
False elevation of liver enzymes or serum bilirubin may occur.
Hypotension (10%); orthostatic effects (1%); cardiac arrest, cerebral vascular accident, MI.
Dizziness (12%); headache (6%); fatigue (3%); stroke.
Rash (2%); Stevens-Johnson syndrome, toxic epidermal necrolysis.
Diarrhea (4%); nausea (2%); vomiting (1%).
Renal function impairment (2%); impotence (1%); acute renal failure, anuria, oliguria, progressive azotemia, uremia.
Bone marrow depression; hemolytic anemia; leukopenia/neutropenia; thrombocytopenia.
Hepatocellular or cholestatic jaundice.
Cough (4%); upper respiratory tract infections (2%); common cold (1%); malignant lung neoplasm.
Chest pain (3%); abdominal pain (2%); asthenia (1%); anaphylactoid reactions; angioedema; symptom complex that includes a positive antinuclear antibody, elevated erythrocyte sedimentation rate, arthralgia/arthritis, myalgia, fever, vasculitis, eosinophilia, and leukocytosis.
When used in pregnancy during the second and third trimesters, ACE inhibitors can cause injury and even death to the developing fetus. When pregnancy is detected, discontinue therapy as soon as possible.
Frequently monitor serum potassium in patients with risk factors for hyperkalemia (eg, renal insufficiency, diabetes mellitus, concomitant use of potassium supplements).
Category D (second and third trimester); Category C (first trimester). Can cause injury or death to fetus if used during the second or third trimester.
Safety and efficacy not established in children younger than 6 yr of age.
Use with caution, usually starting at the low end of the dosage range because of the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant diseases or other drug therapy.
Reduce dose and give less frequently. In renal function impairment, stable elevations in BUN and serum creatinine may occur because of inadequate renal perfusion; monitor renal function during first few weeks of therapy and adjust dosage carefully, especially if glomerular filtration rate is less than 30 mL/min.
Use with extreme caution in patients with hereditary angioedema. Angioedema of the face, extremities, lips, tongue, glottis, larynx, and intestine has been reported in patients treated with ACE inhibitors.
Aortic stenosis/hypertrophic cardiomyopathy
As with other vasodilators, use lisinopril with caution in patients with obstruction in the outflow tract of the left ventricle.
Rarely, ACE inhibitors have been associated with a syndrome that starts with cholestatic jaundice and progresses to fulminant hepatic necrosis and sometimes death.
Significant decreases in BP may occur after first dose, especially in severely salt- or volume-depleted patients or those with heart failure. Minimize risk by discontinuing diuretics, decreasing dose, or increasing salt intake approximately 1 wk prior to initiating drug.
Neutropenia and agranulocytosis
May occur; risk appears greater in patients with renal function impairment, heart failure, or immunosuppression.
Risk of hypotension may be increased.
