Called the reserved powers clause, it's actually not part of the main body of the document (it's the 10th Amendment), and put simply, it says whatever is not explicitly stated as a responsibility of the federal government, is under control of the states.
Atorvastatin is also used to decrease the amount of cholesterol (a fat-like substance) and other fatty substances in the blood. Atorvastatin is in a class of medications called HMG-CoA reductase inhibitors (statins). It works by slowing the production of cholesterol in the body to decrease the amount of cholesterol that may build up on the walls of the arteries and block blood flow to the heart, brain, and other parts of the body.
DRUG DESCRIPTION. LIPITOR is a synthetic lipid-lowering agent. Atorvastatin is an inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase. This enzyme catalyzes the conversion of HMG-CoA to mevalonate, an early and rate-limiting step in cholesterol biosynthesis.
