How Does Crestor Work?

Crestor is a statin medication that effectively lowers lipid levels in the blood, including triglycerides & cholesterol. It restricts HMG-CoA reductase enzymes, which are an important factor in producing cholesterol in the liver. By blocking this enzyme, Creator reduces the bad cholesterol and triglycerides while raising good cholesterol. This action prevents cardiovascular diseases, like heart attacks and strokes, by reducing plaque buildup in the arteries.
