Final answer:
Atorvastatin and Rosuvastatin are statin drugs that help control high cholesterol levels by inhibiting the enzyme HMG-CoA reductase. This reduces the risk of cardiovascular diseases.
Step-by-step explanation:
Atorvastatin (Lipitor) and Rosuvastatin (Crestor) are both statin drugs commonly used to control high cholesterol levels. The main benefit of using these medications is their ability to reduce the synthesis of cholesterol in the body. They do this by inhibiting the enzyme HMG-CoA reductase, which is responsible for cholesterol synthesis. By blocking this enzyme, Atorvastatin and Rosuvastatin lower cholesterol levels in the blood, leading to a reduced risk of cardiovascular diseases, such as heart attacks and strokes.
