Amtor 5 mg/10 mg Tablet is a combination of two medicines: Amlodipine and atorvastatin which treat high blood pressure associated with high cholesterol levels. Amlodipine is a calcium channel blocker (CCB). It works by relaxing blood vessels which makes the heart more efficient at pumping blood throughout the body. Atorvastatin is a lipid-lowering medication which works by blocking an enzyme (HMG-CoA-reductase) that is required in the body to make cholesterol. It thus lowers "bad" cholesterol (LDL), triglycerides and raises "good" cholesterol (HDL). Together they reduce the risk of heart diseases.
