The flow of information can be between two individuals. The information can flow from the individual to a machine, from the machine to the individual and even between two machines.

What is Lipitor? Lipitor (atorvastatin) belongs to a group of drugs called HMG CoA reductase inhibitors, or statins.. Atorvastatin reduces 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).
Atorvastatin is a prescription medicine used to treat high cholesterol. It is marketed as a calcium salt under the brand name Lipitor (atorvastatin calcium), produced by Pfizer. It is also available as a generic medicine. Atorvastatin is a member of the drug class HMG-CoA inhibitor (statin). Atorvastatin works by potentially decreasing the production of cholesterol in the body through blocking the cholesterol-producing enzyme in the liver.
