Alirocumab is a medication used to reduce cholesterol levels. It is a monoclonal antibody that is injected under the skin and works by blocking the action of a protein called PCSK9. This protein prevents the liver from removing LDL cholesterol ("bad" cholesterol) from the blood. By blocking PCSK9, Alirocumab allows the liver to remove more LDL cholesterol, which helps reduce the risk of heart attack and stroke. Alirocumab is typically prescribed to people who have been unable to control their cholesterol levels with lifestyle changes and/or statin medications.
Alirocumab, sold under the brand name Praluent, is a medication used as a second-line treatment for high cholesterol in adults whose cholesterol is not adequately controlled by diet and statin therapy.
Here's a breakdown of its key aspects:
Type of drug:
- Human monoclonal antibody: It belongs to a new class of drugs called PCSK9 inhibitors.
Function:
- Lowers LDL cholesterol ("bad" cholesterol) levels by inhibiting the production of PCSK9.
- PCSK9 is a protein that regulates LDL cholesterol levels. By blocking its production, alirocumab allows the liver to remove more LDL cholesterol from the bloodstream.
Uses:
- Heterozygous familial hypercholesterolemia (HeFH): An inherited condition causing high LDL cholesterol.
- Atherosclerotic cardiovascular disease (ASCVD): A condition where arteries become narrowed due to plaque buildup, increasing the risk of heart attack and stroke.
- Used in combination with other cholesterol-lowering medications like statins or ezetimibe.
Important points:
- Not a first-line treatment: It's typically used after other therapies have proven insufficient.
- Requires injection: Administered subcutaneously (under the skin) by a healthcare professional.
- Potential side effects: Injection site reactions, fatigue, muscle aches, and joint pain.
- Not suitable for everyone: People with certain medical conditions or allergies may not be able to take it.
