Crestor is used to treat high cholesterol. canadian crestor is a cholesterol-lowering medication that blocks the production of cholesterol (a type of fat) in the body. Lowering your cholesterol can help prevent heart disease and hardening of the arteries, conditions that can lead to heart attack, stroke, and vascular disease. Crestor works by reducing levels of "bad" cholesterol (low-density lipoprotein, or LDL) and triglycerides in the blood, while increasing levels of "good" cholesterol (high-density lipoprotein, or HDL).

Accumulation of cholesterol and fats along the walls of your arteries (a process known as atherosclerosis) decreases blood flow and therefore the oxygen supply to your heart, brain, and other parts of your body. Lowering your blood level of cholesterol and fats may help to prevent heart disease, angina (chest pain), strokes, and heart attacks.

It works by preventing the body from forming harmful cholesterol and increasing the amount of HDL (good cholesterol) in your blood. There are many way to buy crestor.
