Mrs. Landon has been diagnosed with coronary artery disease and her following measures to reduce cholesterol by exercise and a low-fat diet were unsuccessful. Given her condition and high cholesterol levels, the physician might prescribe statins as a medication to help lower her cholesterol. Statins, such as Atorvastatin (Lipitor) and Rosuvastatin (Crestor), are specifically designed to reduce cholesterol by inhibiting the enzyme HMG-CoA reductase, which is responsible for the synthesis of cholesterol in the body. Therefore, among the options provided, which includes beta-blockers, diuretics, and antibiotics, statins are the most likely to be prescribed for lowering cholesterol.Statins are drugs that reduce cholesterol levels in the blood. They work by inhibiting the enzyme HMG-CoA reductase, which is responsible for synthesizing cholesterol in the body.
Other lifestyle changes such as regular exercise and a low-fat diet are also important in managing high cholesterol levels.
