lovastatin, Mevacor, Altoprev

Medical and Pharmacy Editor:

GENERIC NAME: lovastatin

BRAND NAME: Mevacor, Altoprev

DRUG CLASS AND MECHANISM: Lovastatin belongs to a class of cholesterol-lowering drugs called HMG-CoA reductase inhibitors, or, more commonly "statins." Other statins include simvastatin (Zocor), atorvastatin (Lipitor), fluvastatin (Lescol), and rosuvastatin (Crestor). Statins reduce cholesterol by inhibiting an enzyme in the liver (HMG-CoA reductase) that is necessary for the production of cholesterol. In the blood, statins lower total cholesterol, low density lipoprotein (LDL) cholesterol ("bad" cholesterol) and triglycerides. LDL cholesterol is believed to be an important cause of coronary artery disease. Lowering LDL cholesterol levels slows and may even reverse coronary artery disease. Statins also increase high density lipoprotein (HDL) cholesterol ("good" cholesterol). Raising HDL cholesterol levels, like lowering LDL cholesterol may slow coronary artery disease. The FDA approved lovastatin in August 1987.

PRESCRIPTION: Yes

GENERIC AVAILABLE: Yes

PREPARATIONS: Tablets: 10, 20, and 40 mg. Extended release tablets: 10, 20, 40, and 60 mg.

STORAGE: Immediate release tablets should be stored between 5-30 C (41-86 F). Extended release tablets should be stored at room temperature, 20-25 C (68-77 F).

PRESCRIBED FOR: Lovastatin is used for reducing total cholesterol and LDL cholesterol, and triglycerides, and for increasing HDL cholesterol in patients with elevated blood cholesterol levels (hypercholesterolemia). Lovastatin is used for reducing the risk of heart attacks, angina, coronary revascularization procedures in individuals without symptomatic cardiovascular disease, average to moderately elevated cholesterol levels and below average HDL cholesterol levels. It also is used for slowing the progression of coronary atherosclerosis in individuals with coronary heart disease.

DOSING: The dose range for lovastatin is 10-80 mg daily given preferably in the evening when it may be most effective. The usual staring dose is 20 mg once daily and the maximum dose is 80 mg daily. Blood cholesterol determinations are performed at regular intervals during treatment so that adjustments in dosage can be made.

DRUG INTERACTIONS: Decreased elimination of lovastatin could increase the levels of lovastatin in the body and increase the risk of muscle toxicity from lovastatin. Examples of drugs that decrease elimination of lovastatin include erythromycin (E-Mycin), ketoconazole (Nizoral), itraconazole (Sporanox), clarithromycin (Biaxin), telithromycin (Ketek), cyclosporine (Sandimmune), nefazodone (Serzone), and protease inhibitors such as indinavir (Crixivan) and ritonavir (Norvir). Large quantities of grape fruit juice (>1 quart daily) also will increase blood levels of lovastatin.

Amiodarone (Cordarone), verapamil (Calan, Verelan, Isoptin), danazol (Danocrine), cyclosporine (Gengraf, Neoral), niacin (Niacor, Niaspan, Slo-Niacin), gemfibrozil (Lopid) and fenofibrate (Tricor) also may increase the risk of muscle toxicity when combined with lovastatin. Patients taking amiodarone (Cordarone) or  verapamil (Calan, Verelan, Isoptin) should not take more than 40 mg of lovastatin. Patients taking niacin (greater than or equal to 1 g/day), gemfibrozil (Lopid), fenofibrate (Tricor) or cyclosporine (Gengraf, Neoral) should not take more than 20 mg of lovastatin.

    • Angina
      • Angina is chest pain that is due to an inadequate supply of oxygen to the heart muscle. Angina can be caused by coronary artery disease or spasm of the coronary arteries. EKG, exercise treadmill, stress echocardiography, stress thallium, and cardiac catheterization are important tests used in the diagnosis of angina.
    • Heart Attack
      • Heart attack happens when a blood clot completely obstructs a coronary artery supplying blood to the heart muscle. A heart attack can cause chest pain, heart failure, and electrical instability of the heart.
    • Heart Disease
      • Heart disease (coronary artery disease) is caused by a buildup of cholesterol deposits in the coronary arteries. Risk factors for heart disease include smoking, high blood pressure, heredity, diabetes, peripheral artery disease, and obesity. Symptoms include chest pain and shortness of breath. There are a variety of tests used to diagnose coronary artery disease. Treatment includes life-style changes, medications, procedures, or surgery.

Lowering your risk factor, lifestyle changes, and in some cases medication are the most effective way of preventing a heart attack.
    • High Cholesterol: Frequently Asked Questions
      • Cholesterol occurs naturally in the body. High blood cholesterol levels increase a person's risk of developing heart disease, heart attacks, strokes, TIAs, and more.

Introduction

Coronary atherosclerosis is the hardening and narrowing of the arteries that supply blood to the heart muscle. Coronary atherosclerosis is the major cause of heart attacks. Heart attacks are the major cause of sudden unexpected death among otherwise healthy adults in the prime of their lives. Heart attacks are also a significant cause of heart failure (due to weakened heart muscle) in this country. Heart failure considerably decreases a person's longevity and quality of life. In dollar terms, coronary heart disease is costly. The total cost of coronary artery bypass surgery, coronary angioplasty and stenting, medications, and hospitalizations exceeds 50 billion dollars annually.

Coronary atherosclerosis, and hence heart attacks, are preventable. A person can significantly lower his or her risk of heart attack by lowering high blood pressure, controlling diabetes, stopping cigarett...
