Niacin and lovastatin Advicor Drug Facts Side Effects and Dosage

Niacin and Lovastatin (Advicor)

Advicor is an oral drug used to lower cholesterol levels in the blood. It combines extended-release niacin and lovastatin. It reduces total cholesterol, LDL cholesterol, and triglycerides while increasing HDL cholesterol.

Niacin is a vital part of the diet necessary for various chemical reactions in the body. It lowers LDL cholesterol and raises HDL cholesterol levels. The mechanism behind niacin’s effects on cholesterol and triglyceride levels is unclear, but it may involve reducing the production of proteins that transport cholesterol and triglycerides in the blood.

Lovastatin belongs to a class of cholesterol-lowering drugs called statins. It inhibits an enzyme necessary for cholesterol production, leading to lower LDL cholesterol and triglyceride levels, and higher HDL cholesterol levels. The combination of niacin and lovastatin is more effective than either drug alone in reducing cholesterol and triglycerides and increasing HDL. The FDA approved Advicor in December 2001.

Side effects of niacin and lovastatin

The most common side effects include flushing, redness, warm sensation, rash, itching, headache, stomach upset, nausea, vomiting, muscle pain, and tingling in extremities. Flushing can be reduced by taking aspirin and increasing the dose of niacin slowly.

Other important side effects include liver test abnormalities, muscle damage, kidney failure, increases in HbA1c and fasting serum glucose, memory loss, forgetfulness, amnesia, confusion, and memory impairment. Statins can also raise blood glucose levels in individuals with diabetes.

Caution should be taken with drug interactions, especially with erythromycin, ketoconazole, clarithromycin, cyclosporine, and grapefruit juice, as they can increase the risk of muscle toxicity from lovastatin. Lovastatin may also interact with warfarin and affect blood clotting. Niacin should not be combined with bile acid sequestrants or alcohol.
