title: Current Drug Options for Raising HDL Cholesterol.
abstract: Although circumstantial evidence supports raising high-density lipoprotein cholesterol (HDLC) in patients with low levels of HDLC, the scarcity of event-based trials has led to uncertainty with regard to the benefit of high-density lipoprotein (HDL)-raising therapy. Based on the National Cholesterol Education Program guidelines, therapy for dyslipidemia is focused initially on targeting low-density lipoprotein cholesterol (LDLC), and in patients with hypertriglyceridemia, secondarily on targeting non-HDLC. When HDLC remains low, the decision to target HDLC depends on the assessment of risk of cardiovascular events. We often consider drug therapy specifically to raise HDLC in high-risk patients, such as those with established atherosclerotic vascular disease, type 2 diabetes, or a Framingham risk score of 20% or above. The majority of high-risk patients require drug therapy, usually a statin, to achieve aggressive LDLC and non-HDLC goals, and thus many patients with low HDLC are candidates for statin therapy. However, a second drug is often required to achieve substantial HDL raising. Although no formal goals for HDLC exist, reasonable goals are HDLC greater than 40 mg/dL in men and greater than 50 mg/dL in women. We often add either niacin or a fibrate to a statin in high-risk patients with low HDLC levels. Targeting HDLC with pharmacologic therapy is a more difficult decision in moderate-risk patients, in whom therapy must be highly individualized.
