Doctors' Answers to "Frequently Asked Questions" - Angioplasty
Answer: Probucol is a cholesterol lowering agent that belongs to the general class of drugs called HMG Co A reductase drugs. These drugs lower cholesterol by inhibiting the enzyme in the liver that is responsible for cholesterol metabolism. It like its cousins is the most effective class of agents for lowering cholesterol. There have been several studies showing an improvement in survival and lowering 2nd heart attacks in patients who lower their cholesterol after bypass surgery. This has been consequently been thought to lower 2nd heart attacks in angioplasty and shunt placements. The data here is less well done than in bypass patients; but, most physicians assume there is the same effect. It appears in bypass patients to help if it lowers cholesterol below 200. Lowering below 200 appears less certain-although I routinely do it and so do many other physicians.
