Step-by-step explanation:
The generic name of the drug Lipitor is Atorvastatin. Lipitor belongs to a class of drugs called statins, which are used to reduce cholesterol levels in the body. These drugs function by inhibiting a key enzyme known as HMG-CoA reductase, which is vital in the synthesis of cholesterol from lipids. Statins like Atorvastatin and Rosuvastatin (Crestor) are prescribed to manage hyperlipoproteinemia and to decrease the risk of cardiovascular disease by lowering blood cholesterol levels. As high cholesterol can lead to various health issues, including heart disease, the use of statins plays a critical role in preventative healthcare.
