Statins are specifically prescribed to lower cholesterol levels in the body. They work by inhibiting an enzyme in the liver that is responsible for producing cholesterol, effectively reducing the levels of low-density lipoprotein (LDL) cholesterol, commonly referred to as "bad" cholesterol. High levels of LDL cholesterol are associated with an increased risk of cardiovascular diseases, including heart attacks and strokes. Consequently, by lowering LDL cholesterol, statins contribute to improved heart health and a reduced risk of these serious conditions.

In the context of the other options, the medications mentioned do not serve the purpose of statins. Reducing blood glucose levels pertains to medications used in managing diabetes, while preventing excess calcium absorption relates to treatments aimed at conditions involving calcium metabolism. Finally, alleviating symptoms of anxiety would involve the use of anxiolytic medications or antidepressants, not statins. Thus, the role of statins is clearly defined as lowering cholesterol levels, helping to manage cardiovascular risk effectively.
