Atortan 40mg Tablet is a statin. It is used to lower cholesterol and lessen the risk of cardiovascular disease. High cholesterol levels can cause blood arteries to constrict (atherosclerosis), increasing your risk of having a stroke or heart disease. Lowering your intake of this fat minimizes the likelihood of this happening and allows you to stay healthier for longer. Even if you are feeling OK, continue to take this medication.
