Anzitor EZ 20/10 mg is a combination medication containing Atorvastatin (20 mg) and Ezetimibe (10 mg). It is used to lower elevated levels of total cholesterol, low-density lipoprotein cholesterol (LDL-C), and triglycerides, and to increase high-density lipoprotein cholesterol (HDL-C) in patients with primary hyperlipidemia or mixed dyslipidemia. This combination works by inhibiting cholesterol synthesis in the liver and reducing cholesterol absorption in the intestines.
