Generic Name: simvastatin
Simvastatin is a medication that physicians prescribe to reduce the amount of cholesterol and triglycerides circulating in the body. High cholesterol and triglycerides are associated with increased risk of heart disease, stroke and heart attack (MedlinePlus, 2013). The medication belongs to the drug class known as statins or HMG-CoA reductase inhibitors.
Read the FDA description of simvastatin.
The body naturally produces cholesterol, and cholesterol is present in foods such as red meat with visible fat on it. When a person takes statins, the medication works to reduce the body’s cholesterol production. A physician typically recommends taking simvastatin along with making lifestyle changes, such as diet and exercise (MedlinePlus, 2013).
