R.M.'s physician adds niacin, a vitamin preparation (folic acid, vitamin B6, and vitamin B12 [Foltx]) daily with food, and omega-3 fatty acids to his list of medications. How do these medications affect lipids? R.M. states, "But I already take Lipitor
What do all these medications do?" How do you answer him?
• Atorvastatin (Lipitor) is a "statin," also known as an HMG-CoA reductase inhibitor, and works to
reduce cholesterol synthesis. It is used to reduce elevated cholesterol and triglyceride levels, and
thus aids in the prevention of cardiovascular disease.
• Folic acid, B6, and B12 are B vitamins that will help stabilize arteries and prevent restenosis of
lesions that have been angioplastied or stented. In addition, they might help reduce the elevated
homocysteine level.
• Niacin will increase HDL particles and provide more protection to the arteries and also works to
reduce cholesterol, LDL, and triglyceride levels.
• Omega-3 fatty acids will help increase HDL and decrease triglycerides. They are also helpful in
preventing sudden cardiac death.
