What is lisinopril?
Lisinopril is a class of angiotensin-converting enzyme (ACE) medicine which uses mainly for the treatment or prevention of high blood pressure and heart failure. The dosage of lisinopril causes various types of side effects on human health. Therefore, always ask your doctor or physician before taking the lisinopril dose.
It works by inhibiting the renin-angiotensin-aldosterone system (RAAS). The full effect is observed after taking four weeks of lisinopril dose.
Lisinopril is an antihypertensive drug prescribed by the doctor mainly for the treatment of high blood pressure or hypertension in adults and children.
It is available in the market under the following brand names Zestoretic, Zestril, Prinivil, and Qbrelis. It is taken by mouth but for people who have unable to take a tablet, doctors prescribed its oral solution.
The generic drug lisinopril helps in the treatment of certain types of heart failure or after a heart attack. It is a class of angiotensin-converting enzyme (ACE) inhibitors that inhabit the production of a protein that causes blood vessels to tighten. It is also used for some patients who suffer from moderate kidney disease.
Always tell your doctor and pharmacist before taking it. If you have certain types of angioedema, heart disease, kidney disease, diabetes, and surgery including dental surgery, you should consult before taking lisinopril.
How does lisinopril work?
It acts on renin–angiotensin–aldosterone system (RAAS) to prevent the conversion of angiotensin I to angiotensin II.
Lisinopril work by reduction of the amount of angiotensin II in your body. The reduction of angiotensin II causes us to relax our arterioles and reduces the release of aldosterone from the adrenal cortex. Hence our kidneys can excrete sodium along with water into the urine which increases the retention of potassium ions.
How quickly does lisinopril lower blood pressure?
Lisinopril dose can be lowering blood pressure about an hour after being taken. You can take it with or without food because food does not affect the absorption of such a drug.
Lisinopril dosage is available in the market as a tablet or oral solution with different strengths. The tablet forms are available in the strength of 2.5 mg, 5 mg, 10 mg, 20 mg, 30 mg, and 40 mg. The oral solution is available in the strength of 1 mg per milliliter (mL).
You should regularly check your blood pressure level to determine the response to lisinopril medication. The common dosages for adults are given below the table,
|Indication||Initial dosage||Maximum dosage|
|High blood pressure||10 mg/day||80 mg/day|
|Heart failure||2.5–5 mg/day||40 mg/day|
|Heart attack||5 mg/day||If the initial dose does not enough, you may take a maximum of 10 mg/day or your doctor can prescribe an accurate dosage.|
Dosage for high blood pressure
Lisinopril work by blocking an enzyme in our body which produces angiotensin II, a substance that tightens and narrows blood vessels. If your body does not produce angiotensin II, your blood vessels are wider. Therefore, your blood pressure goes down.
Doctors can prescribe only a single daily dose for controlling your blood pressure.
The starting dose for adults is 10 mg orally once per day. If starting dose does not enough to reduce your blood pressure, you may take 10 to 80 mg orally per day but not exceed 80 mg per day.
Lisinopril is an FDA-approved medication used for the treatment of hypertension in children above 6+ years old. The standard dosage for 6+ years children is 0.07–0.61 mg/kg per day with a maximum dose of 40 mg per day.
Always consult your doctor before applying lisinopril medication to your children.
Dosage for heart failure
An ACE inhibitor is used with diuretic drugs such as digoxin to give additional advantages to congestive heart failure and hyponatremia. It is a condition in which your heart does not pump enough blood to your body. It widens the blood vessels and increases the flow of blood from the heart to your body.
The standard dosage for congestive heart failure is 2.5–5 mg orally once per day with a maximum dosage of 40 mg per day.
Dosage for heart attack
In many cases or early stages of myocardial infarction or heart attack, many doctors prescribe ACE inhibitor lisinopril which reduces mortality and cardiovascular morbidity in patients.
The starting dose for adults is 5 mg orally once per day. If starting dose does not enough, you may take 10 mg orally per day for at least 6 weeks. The main aim of lisinopril therapy in heart failure is to increase blood flow from other organs to the heart muscle to prevent further damage.
