Physical properties of lipitor vs. zocor

Zocor and Lipitor are prescribed for
Lipitor and Zocor both are taken to reduce high blood pressure caused by cholesterol and reduce the risk of heart attack and stroke for those with clogged arteries.
How zocor and lipitor work
Lipitor works to break down colesterol deposits that collect within the blood vessels of the body to reduce high blood pressure. If colesterol deposits develop in the blood vessels of the heart, they can cause a heart attack. Liptor is an alternative to angioplasty or blood thinning methods of blood pressure reduction. Lipitor uses a HMG-CoA reductase inhibitor to reduce Low Density Cholesterol. Liptor works by enzyme blocking. The drug blocks an enzyme in the liver that leads to the reduction of Low Density Cholesterol that can lead to a heart attack or stroke.
Zocor functions in a similar manner to dissolve cholesterol deposits within blood vessels that cause high blood pressure and heart attack. The patent on Zocor expired recently allowing for reduced cost generic versions of the drug. Some studies suggest Zocor may be less effective than Liptor. Zocor uses a lipid reducing agent to reduce Low Density Cholesterol.
