    Do you have information about Statins
    ### Response:
    Summary : Statins are drugs used to lower cholesterol. Your body needs some cholesterol to work properly. But if you have too much in your blood, it can stick to the walls of your arteries and narrow or even block them.    If diet and exercise don't reduce your cholesterol levels, you may need to take medicine.
