  • Title: [Treatment of dyslipidemia: how and when to combine lipid lowering drugs].
    Author: Schulz I.
    Journal: Arq Bras Endocrinol Metabol; 2006 Apr; 50(2):344-59. PubMed ID: 16767301.
    Abstract:
    Familial combined hyperlipidemia (FCH) is a frequent familial lipid disorder associated with insulin resistance, low HDL cholesterol, high triglycerides and cholesterol levels with variable phenotypes within the same family. FCH is linked to a high risk for cardiovascular diseases. Treatment goals for lipid abnormalities are changing in recent years. Lowering elevated levels of LDL e Non HDL-cholesterol levels are primary targets of therapy. Lower LDL-C than 70 mg/dL seems to be useful to lower cardiovascular risk in patients with very high risk. Many statins are available, with different potencies and drug interactions. Combination therapy of statins and bile acid sequestrants or ezitimibe may be necessary to further decrease LDL cholesterol levels in order to meet guideline goals. High triglycerides and low HDL cholesterol are also important goals in the treatment of these patients, and frequently statins alone are insufficient to normalize the lipid profile. Combination therapy with fibrates will further lower triglycerides and increase HDL cholesterol levels; this combination is also associated with higher incidence of myopathy and liver toxicity; appropriate evaluation of patients' risk and benefits is necessary. Association of statin/niacin seems be very useful in patients with FCH, especially as niacin is the best drug to increase HDL cholesterol; this association is not linked to a higher frequency of myopathy. Niacin causes flushing, that can in part be managed with use of aspirin and extended release forms (Niaspan); niacin also may increase plasma glucose and uric acid levels. Evaluation of risks and benefits for each patient is needed.
