Which condition is Pravastatin Sodium used to prevent?

Pravastatin Sodium is primarily used to prevent coronary artery disease by lowering cholesterol levels in the blood. It belongs to a class of medications known as statins, which work by inhibiting the enzyme HMG-CoA reductase, a crucial step in the cholesterol production pathway in the liver. By lowering low-density lipoprotein (LDL) cholesterol levels, Pravastatin helps reduce the risk of plaque buildup in the arteries, thereby decreasing the incidence of heart attacks and other cardiovascular events associated with coronary artery disease.

The other conditions listed are not indications for Pravastatin. Diabetes mellitus is a different health issue that requires distinct management strategies; chronic obstructive pulmonary disease (COPD) is a respiratory condition unrelated to cholesterol metabolism; hyperthyroidism is an endocrine disorder, also not affected by statin therapy. Therefore, the use of Pravastatin Sodium is specifically associated with the prevention of coronary artery disease, making this the correct choice.
