Caduet is used to treat high blood pressure and high cholesterol (fat in the blood). Caduet can also be used for angina (a certain type of chest pain). Caduet can be used in people who have high blood pressure and coronary heart disease (CHD) or who are at risk of CHD (for example, if they have diabetes, a history of stroke, or small blood vessel disease). In these people, Caduet is used to help reduce the risk of having a heart attack or stroke. Caduet contains a combination of two medicines. One is amlodipine and the other is atorvastatin. Amlodipine belongs to a group of medicines called calcium channel blockers. They work by relaxing your blood vessels, making it easier for your heart to pump blood around the body and help increase the supply of blood and oxygen to your heart. Calcium channel blockers do not change the amount of calcium in your blood or bones. Atorvastatin belongs to a group of medicines called statins. It works by reducing the amount of cholesterol made by the liver. It reduces the 'bad' cholesterol and can raise the 'good' cholesterol. Atorvastatin also helps to protect you from a heart attack or stroke.
