Lisinopril

What Is Lisinopril?

Lisinopril belongs to the group of drugs called ACE inhibitors, which is used to treat high blood pressure. Sometimes, it is also used in the treatment of heart failure. High blood pressure increases the risk of heart attacks, stroke, and kidney diseases. This drug reduces blood pressure by relaxing the blood vessels.

Points to Remember:

  1. Lisinopril is used to treat hypertension.

  2. This medicine increases your chance of surviving a heart attack.

  3. It is available as an oral tablet and solution.

  4. It is contraindicated during pregnancy or if you are trying to get pregnant.

  5. This drug can cause angioedema, which can cause severe swelling of the face, arms, lips, tongue, and throat leading to breathing difficulty.

  6. When you first start taking it, it can result in low blood pressure.

  7. You might have persistent cough while on this medicine.

  8. Avoid taking this medicine before or after 36 hours of using Sacubitril.

  9. Do not use this with any medicine containing Aliskiren.

  10. Potassium and creatinine monitoring are needed with this medicine if you have kidney disease.

What Is Lisinopril Used For?

Lisinopril is used alone or in combination with medicines to treat hypertension. High blood pressure can affect the heart and arteries, which in the long run, impairs their function. This damage to the blood vessels of the brain, heart, and kidneys, can result in stroke, heart failure, or kidney failure. Thus, using this medicine will reduce the risk of cardiovascular diseases.

It can also be used to treat heart failure, and in some patients after a heart attack. Some of the heart muscles are damaged and weakened after a heart attack, which makes it difficult for the heart to pump blood. Lisinopril is given for individuals with low heart function in order to preserve, improve or slow the progression of the disease.

How Does Lisinopril Work?

In the renin-angiotensin-aldosterone system (RAAS), Lisinopril blocks the actions of angiotensin-converting enzyme (ACE), which prevents the conversion of angiotensin I to angiotensin II. This affects the adrenal cortex, which prevents the release of aldosterone. This action makes the kidney excrete sodium and retain potassium ions. This inhibition of the RAAS system lowers blood pressure and increases the supply of blood and oxygen to the heart.

What Is the Dosage of Lisinopril?

Lisinopril is available in 2.5, 5, 10, 20, 30, and 40 mg strengths.

  • The dosage for high blood pressure is 20 to 40 mg taken once per day, up to 80 mg taken once per day.

  • The dosage for heart failure is 5 mg orally once per day, up to 40 mg taken once per day.

  • The dosage after a heart attack is 5 mg orally within the first 24 hours. Then if needed, another 5 mg after 24 hours. After this, 10 mg once per day for a minimum of 6 weeks.

How Is Lisinopril Taken?

It should be taken as prescribed by your doctor, and follow the instructions on the prescription label. Depending on how you react to the drug, your doctor might alter the doses. It can be taken with or without food. The solution form should be measured properly with a dose-measuring spoon or medicine cup. Your blood pressure, kidney function, and electrolytes need to be monitored regularly. Do not stop taking this medicine even after your blood pressure is under control, as it usually needs to be taken life long.

What Are the Drugs That Lisinopril Can Interact With?

Lisinopril can interact with other medications you might be taking, which might change the way the drug works. This can make the drug not work properly or cause unwanted side effects. To prevent this, always inform the doctor about all the medicines, herbs, and supplements that you are currently taking. The drugs with which Lisinopril can interact are:

  • Antihypertensive drugs -

    • Angiotensin receptor blockers (ARB) - Candesartan, Eprosartan, and Olmesartan.

    • Angiotensin-converting enzyme (ACE) inhibitors - Benazepril, Ramipril, and Captopril.

    • Renin-inhibitors - Aliskiren

  • Anti-diabetic drugs - Insulin and oral anti-diabetic drugs.

  • Diuretics - Hydrochlorothiazide and Furosemide.

  • Potassium supplements.

  • Potassium-sparing diuretics - Spironolactone and Amiloride.

  • Lithium.

  • Nonsteroidal anti-inflammatory drugs (NSAIDs) - Ibuprofen and Naproxen.

  • Neprilysin inhibitors - Sacubitril.

Lisinopril is used for long-term treatment of hypertension. This drug if not taken as prescribed can cause serious side effects. If you stop taking it abruptly, your blood pressure might rise, which can increase your heart rate, cause sweating and anxiety. Taking it irregularly will not help control blood pressure, which puts you at higher risk for heart attack and stroke.

The doctor will monitor your blood pressure regularly and look out for any side effects. To know other ways to treat hypertension, consult a doctor online.
