Crestor works by stopping the production of cholesterol in the body by blocking the responsible enzymes. Individuals with high cholesterol levels have a higher risk of heart diseases such as heart attacks.

What is Crestor For?

Crestor contains rosuvastatin, a drug that is classified under a group of medicines known as statins or HMG CoA reductase inhibitors. This group of medicines are prescribed to help treat people with cholesterol problems, inherited or otherwise.

Crestor is also a medication used to help prevent heart attacks, stroke, angioplasty for people with 2 risk factors for heart and blood vessel disease. Rosuvastatin is the generic name and Crestor is the branded name.  

Crestor: How Does it Work?

With the active ingredient rosuvastatin, Crestor works by controlling the production of cholesterol by the liver. The enzymes responsible for cholesterol are blocked. This action will result in bringing down cholesterol levels. With a low level of cholesterol, the risks of having heart attacks or stroke or other heart diseases are significantly reduced.

Crestor, combined with a healthy diet and exercise will contribute to having low bad cholesterol levels.

You can expect to see the maximum effect on your cholesterol levels in about 2 to 4 weeks of taking Crestor.
