Ezetimibe/simvastatin is a drug combination used for the treatment of dyslipidemia. It is a combination of ezetimibe (known as Zetia in the United States) and the statin drug simvastatin (known as Zocor in the US). Ezetimibe reduces blood cholesterol by acting at the brush border of the small intestine and inhibiting the absorption of cholesterol, leading to a decrease in the delivery of intestinal cholesterol to the liver.
