Final answer:
If lifestyle changes are insufficient, Mrs. Landon's physician might prescribe statins or other cholesterol-lowering medications such as fibrates, ezetimibe, niacin, or bile acid sequestrants to help manage her high cholesterol levels.
Step-by-step explanation:
If Mrs. Landon's cholesterol level is still unacceptably high despite lifestyle changes, her physician might prescribe medication to help lower her cholesterol. One common type of medication for this purpose is statins, which reduce the level of cholesterol in the blood and decrease the risk of coronary artery disease. In some cases, a physician may also recommend other medications such as fibrates, ezetimibe, niacin, or bile acid sequestrants. These drugs work in different ways to help reduce cholesterol levels or improve the LDL:HDL ratio in the body.
It's essential for Mrs. Landon to continue her efforts with dietary modifications and physical activity, as these lifestyle changes work in conjunction with medication to manage cholesterol levels effectively. If she has been smoking, quitting can also provide significant benefits to her cholesterol profile and overall cardiovascular health.
