Lisinopril Uses, Dosage, Side Effects, Food Interaction and all others data.

Lisinopril competitively inhibits ACE from converting angiotensin I to angiotensin II (a potent vasoconstrictor) resulting in increased plasma renin activity and reduced aldosterone (a hormone that causes water and Na retention) secretion. This promotes vasodilation and BP reduction.

Lisinopril is an angiotensin converting enzyme inhibitor used to treat hypertension, heart failure, and myocardial infarction. Lisinopril is not a prodrug, and functions by inhibition of angiotensin converting enzyme as well as the renin angiotensin aldosterone system. It has a wide therapeutic index and a long duration of action as patients are generally given 10-80mg daily.

Hypertension: Lisinopril is used for the treatment of hypertension in adult patients and pediatric patients 6 years of age and older to lower blood pressure. Lowering blood pressure lowers the risk of fatal and non-fatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes.

Control of high blood pressure should be part of comprehensive cardiovascular risk management, including, as appropriate, lipid control, diabetes management, antithrombotic therapy, smoking cessation, exercise, and limited sodium intake. Many patients will require more than 1 drug to achieve blood pressure goals. For specific advice on goals and management, see published guidelines, such as those of the National High Blood Pressure Education Program’s Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC).

Numerous antihypertensive drugs, from a variety of pharmacologic classes and with different mechanisms of action, have been shown in randomized controlled trials to reduce cardiovascular morbidity and mortality, and it can be concluded that it is blood pressure reduction, and not some other pharmacologic property of the drugs, that is largely responsible for those benefits. The largest and most consistent cardiovascular outcome benefit has been a reduction in the risk of stroke, but reductions in myocardial infarction and cardiovascular mortality also have been seen regularly.

Elevated systolic or diastolic pressure causes increased cardiovascular risk, and the absolute risk increase per mmHg is greater at higher blood pressures, so that even modest reductions of severe hypertension can provide substantial benefit. Relative risk reduction from blood pressure reduction is similar across populations with varying absolute risk, so the absolute benefit is greater in patients who are at higher risk independent of their hypertension (for example, patients with diabetes or hyperlipidemia), and such patients would be expected to benefit from more aggressive treatment to a lower blood pressure goal.

Some antihypertensive drugs have smaller blood pressure effects (as monotherapy) in black patients, and many antihypertensive drugs have additional approved indications and effects (e.g., on angina, heart failure, or diabetic kidney disease).

These considerations may guide selection of therapy.Lisinopril may be administered alone or with other antihypertensive agents.

Heart Failure: Lisinopril is used to reduce signs and symptoms of heart failure in patients who are not responding adequately to diuretics and digitalis.

Acute Myocardial Infarction: Lisinopril is used for the reduction of mortality in treatment of hemodynamically stable patients within 24 hours of acute myocardial infarction. Patients should receive, as appropriate, the standard recommended treatments such as thrombolytics, aspirin and beta-blockers

Lisinopril is also used to associated treatment for these conditions: Acute Myocardial Infarction (AMI), Cardiovascular Events, Congestive Heart Failure (CHF), Diabetic Nephropathy, High Blood Pressure (Hypertension), Migraine

How Lisinopril works

Angiotensin II constricts coronary blood vessels and is positively inotropic, which under normal circumstances, would increase vascular resistance and oxygen consumption. This action can eventually lead to myocyte hypertrophy and vascular smooth muscle cell proliferation.

Lisinopril is an angiotensin converting enzyme inhibitor (ACEI), preventing the conversion of angiotensin I to angiotensin II. This action prevents myocyte hypertrophy and vascular smooth muscle cell proliferation seen in untreated patients. Increased levels of bradykinin also exhibit vasodilating effects for patients taking ACEIs. Lisinopril also inhibits renin's conversion of angiotensin to angiotensin I.


Lisinopril dosage

Oral (Adult)-


Initially, 10 mg/day, 1st dose given preferably at bedtime to avoid precipitous fall in BP. Patient with renovascular HTN, volume depletion, severe HTN: Initially, 2.5-5 mg once daily. Patient on diuretic: Initially, 5 mg once daily. Maintenance: 20 mg once daily, up to 80 mg/day may be given if needed.

Diabetic nephropathy: Hypertensive type 2 diabetics with microalbuminuria: 10 mg once daily, may increase to 20 mg once daily to achieve a sitting diastolic BP

Heart failure: As adjunct: Initially, 2.5 or 5 mg/day, increased by increments of ≤10 mg at intervals of at least 2 wk to max maintenance dose of 40 mg/day.

Post-myocardial infarction: Initially, 5 mg once daily for 2 days started within 24 hr of the onset of symptoms. Increase to 10 mg once daily. Patients with low systolic BP: Initially, 2.5 mg once daily.

Oral (Child)-

Hypertension: ≥6 yr Initially, 0.07 mg/kg, up to 5 mg once daily.

Side Effects

Headache, fatigue, persistent and non-productive cough, chest and abdominal pain, dizziness, nausea, vomiting, diarrhoea, upper resp tract infection, asthenia, rash, orthostatic effects, hypotension, renal dysfunction, hyperkalaemia, intestinal angioedema; increased BUN and serum creatinine levels.


The oral and subcutaneous LD50 in rats is >8500mg/kg and in mice is >9100mg/kg. The oral LDLO in women is 1200µg/kg/16D and in men is 43mg/kg/43W.

Patients experiencing an overdose of lisinopril may present with hypotension. Patients should be treated with intravenous saline to restore blood pressure. Lisinopril can be removed from the blood by hemodialysis due to it not being protein bound.


Bilateral renal artery stenosis or a single kidney with unilateral renal artery stenosis. Patients with collagen vascular disease, acute MI at risk of further haemodynamic deterioration, angioedema unrelated to ACE inhibitor therapy, aortic stenosis and hypertrophic cardiomyopathy. Increased risk of angioedema in black patients. Renal impairment. Lactation. Childn <6 yr.


May enhance hypotensive effect with diuretics. May increase risk of renal function deterioration and decrease antihypertensive effect with NSAIDs. May increase serum levels and toxicity of lithium. Increased risk of hyperkalaemia with K-sparing diuretics and K supplements. May increase nitritoid reactions of gold Na thiomalate.

Food Interaction

  • Avoid hypertensive herbs (e.g. bayberry, blue cohosh, cayenne, ephedra, and licorice).
  • Avoid potassium-containing products. Potassium products increase the risk of hyperkalemia.
  • Limit salt intake. Salt may attenuate the antihypertensive effect.
  • Take with or without food. The absorption is unaffected by food.

[Moderate] GENERALLY AVOID: Moderate-to-high dietary intake of potassium can cause hyperkalemia in some patients who are using angiotensin converting enzyme (ACE) inhibitors.

In some cases, affected patients were using a potassium-rich salt substitute.

ACE inhibitors can promote hyperkalemia through inhibition of the renin-aldosterone-angiotensin (RAA) system.

MANAGEMENT: It is recommended that patients who are taking ACE inhibitors be advised to avoid moderately high or high potassium dietary intake.

Particular attention should be paid to the potassium content of salt substitutes.

Volume of Distribution

The apparent volume of distribution of lisinopril is 124L.

Elimination Route

Lisinopril is 6-60% orally bioavailable with an average of 25% bioavailability. Lisinopril reaches a Cmax of 58ng/mL with a Tmax of 6-8h. Lisinopril's absorption is not affected by food.

Half Life

Elimination Route

Lisinopril is entirely eliminated exclusively in the urine.

Pregnancy & Breastfeeding use

Category D: There is positive evidence of human foetal risk, but the benefits from use in pregnant women may be acceptable despite the risk (e.g., if the drug is needed in a life-threatening situation or for a serious disease for which safer drugs cannot be used or are ineffective).
