Generic Zocor (simvastatin) belongs to a group of drugs called HMG CoA reductase inhibitors, or "statins". Simvastatin reduces levels of "bad" cholesterol (low-density lipoprotein, or LDL) and triglycerides in the blood, while increasing levels of "good" cholesterol (high-density lipoprotein, or HDL).
Generic Zocor is used to lower cholesterol and triglycerides (types of fat) in the blood.
Generic Zocor is also used to lower the risk of stroke, heart attack, and other heart complications in people with diabetes, coronary heart disease, or other risk factors.
