What is Simvastatin?
Simvastatin is a prescription medication that belongs to a class of drugs called statins (HMG-CoA reductase inhibitors). It is widely used to lower bad cholesterol (LDL) and triglycerides while increasing good cholesterol (HDL) in the blood.
It is commonly prescribed to reduce the risk of heart attack, stroke, and cardiovascular disease.
How Simvastatin Works
Simvastatin works by blocking an enzyme in the liver responsible for producing cholesterol. This helps:
- Lower LDL (bad cholesterol) levels
- Reduce triglycerides in the blood
- Increase HDL (good cholesterol)
- Prevent plaque buildup in arteries
By improving cholesterol balance, it supports long-term heart health.
Uses of Simvastatin
Simvastatin is prescribed for:
- High cholesterol (hyperlipidemia)
