Nicotinic Acid Agents

Niacin, Niacor and Slo-Niacin are common names for nicotinic acid agents. Nicotinic acid, which is also called niacin, is a water soluble vitamin B.  It improves levels of all lipoproteins when the doses are given far above the vitamin requirement.

Nicotinic acid reduces total cholesterol, LDL and triglycerides at the same time raising HDL.  It reduces LDL by 10 to 20%, triglycerides by 20 to 50% and raises HDL by 15 to 35%.  Nicotinamide is a niacin by product after the body breaks it down.  Nicotinamide has no effect in lowering cholesterol and should not be used in place of nicotinic acid.

Individuals who are allergic to nicotinic acid, and those who have liver disease, active peptic ulcer, or arterial bleeding, should not use nicotinic acid agents.

There are two types of nicotinic acid.  One for immediate release and one for extended release.  Immediate release is inexpensive and widely available without a prescription.  However, because of potential side effects it must not be used for lowering cholesterol without being monitored by a doctor.
Niacin that is extended release is often tolerated better than crystalline niacin.  But has a greater chance of causing damage to the liver.

If you are taking medication for high blood pressure, the results may be increased while taking niacin.  You should have a system available to monitor your blood pressure when beginning a new niacin regimen.
Again, there may be side effects when mixed with other medications or foods.  Discuss with your doctor and make certain you make him aware of all medications prescribed or otherwise.
