Prevastatin, commonly known as pravastatin, is a medication used to lower cholesterol levels in the blood. It belongs to a class of drugs called statins, which work by inhibiting an enzyme involved in cholesterol production in the liver. This helps reduce the risk of cardiovascular diseases, including heart attacks and strokes, by improving overall lipid profiles. Additionally, pravastatin may have other benefits, such as reducing inflammation and stabilizing plaque in the arteries.
