Final answer:
Statins are a class of drugs that inhibit cholesterol synthesis in the liver by blocking the enzyme HMG-CoA reductase. Acetaminophen is another drug that may reduce cholesterol synthesis, although its mechanism of action is not completely known.
Step-by-step explanation:
Statins are a class of drugs that reduce cholesterol levels by inhibiting the enzyme HMG-CoA reductase in the liver, which is responsible for synthesizing cholesterol from lipids in the body. By blocking this enzyme, statins effectively decrease cholesterol synthesis in the liver.
Other drugs that can reduce cholesterol levels include acetaminophen, which is an inhibitor of the enzyme cyclooxygenase. However, the exact mechanism of acetaminophen's action in reducing cholesterol synthesis is still not fully understood.
