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. Machines coupled together through networks also provide signals for the individuals to respond, thus a type of communication system.
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).
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.
