About Leqvio

Doctors prescribe Leqvio for lowering the high cholesterol in the body. Leqvio is the trade name for the drug to reduce the LDL (low-density lipoprotein or bad cholesterol) in adults with familial hypercholesterolemia, atherosclerotic cardiovascular disease, and primary hyperlipidemia.

Familial hypercholesterolemia is an inherited disease that increases the risk of developing cardiac (heart) issues at a younger age by raising the cholesterol levels in the body.

Atherosclerotic cardiovascular disease is the condition of plaque (fat deposit) builds up in the arteries resulting in hardening and narrowing of the passage and heart problems.

Primary hyperlipidemia is a disorder caused due to hereditary reasons and runs in families. It results in high cholesterol and triglycerides (fat) in the body.

Depending on the patient’s situation, the physician might advise Leqvio with a low-fat, balanced diet, exercise, and other drugs viz; statin or diet only. The doctor might also recommend Leqvio for other disorders.

Leqvio is a fluid solution, and physicians inject it under the skin.

Mode of action of Leqvio

  • Leqvio functions by assisting the liver cells in eliminating the body’s bad cholesterol (LDL)
  • Our liver cells have LDL (low-density lipoprotein) receptors that help remove low-density lipoprotein from the blood. The LDL is further fragmented in the liver and eliminated from the body.
  • But in diseased conditions, the LDL receptors get damaged by a liver protein known as PCSK9; hence, the body’s LDL cholesterol increases.
  • Leqvio functions by preventing the liver’s PCSK9 protein production, lowering the body’s LDL or bad cholesterol 3Overview| Researched based study from

Uses of Leqvio

The FDA has permitted Leqvio to treat the following conditions:

  • Atherosclerotic cardiovascular disease
  • Familial hypercholesterolemia (a type of hyperlipidemia)
  • Primary hyperlipidemia

Atherosclerotic cardiovascular disease

  • It is the condition of fat deposits (plaque) in the arterial walls, thereby narrowing the arterial passages. It is the chief cause of heart attacks and strokes among people.

Familial hypercholesterolemia

  • It is a hereditary disease that can cause increased cholesterol levels right from birth.

Primary hyperlipidemia

  • This disorder causes increased cholesterol and triglyceride levels due to genetic anomalies (abnormalities). This type runs for generations.

Leqvio effectively treats the above-listed conditions by lowering the cholesterol levels in the body. The physician often advises patients to take Leqvio with a low-fat, well-balanced diet and statin medication.

The fact is that certain cholesterol-lowering medications lower the chances of stroke, heart attack, and death associated with high cholesterol. Still, researchers lack information on whether Leqvio can reduce the high cholesterol fatal risk. So, doctors often do not prescribe Leqvio alone and advice another drug, statin, to lower cholesterol-related catastrophic risk 5Uses| Researched based study from
