Final answer:
All medications listed, including A) Lipitor, B) Gemfibrozil, and C) Simvastatin, are antilipidemic agents used to lower blood lipid levels and manage hyperlipoproteinemia.
Step-by-step explanation:
The question is asking which medication listed is not an antilipidemic agent. Antilipidemic agents are medications used to lower lipid levels in the blood, and they include several classes of drugs. Statins, such as Atorvastatin (Lipitor) and Simvastatin, are a class of antilipidemic agents that reduce cholesterol levels and the risk of coronary artery disease.
Gemfibrozil is another medication that belongs to the fibrate class and is used to lower lipid levels, particularly triglycerides. Therefore, the correct answer to the question is: D) All of the above are antilipidemic agents. Each medication listed, A) Lipitor, B) Gemfibrozil, and C) Simvastatin, functions as an antilipidemic agent to help in the treatment and management of high blood lipid levels.
