Objective: To compare the effectiveness of the ternarydrug combination of colestipol, niacin, and lovastatin with binary combinations of those drugs in treating patients with familial hypercholesterolemia.
Design: An open sequential study of serum lipoprotein responses in patients receiving diet alone (mean duration, 4 months); colestipol and niacin with diet (mean duration, 9 months); and colestipol, niacin, and lovastatin with diet (mean duration, 15 months).
Setting: Metabolic ward and lipid clinic of a university medical center.
Patients: Twenty-two patients with clinical characteristics of familial hypercholesterolemia (low-density-lipoprotein cholesterol, > 8.48 mmol/L; 21 of 22 with tendon xanthomas).
Interventions: Diet: less than 200 mg/d of cholesterol and less than 8% of total calories from saturated fat; colestipol, 30 g/d; lovastatin, 40 to 60 mg/d; and niacin, 1.5 to 7.5 g/d.
Measurements and Main Results: Mean total serum cholesterol and low-density-lipoprotein cholesterol levels of 4.86 ± 0.62 mmol/L (188 ± 24 mg/dL SD) and 2.89 ± 0.54 mmol/L (112 ± 21 mg/dL SD), respectively, were significantly lower during ternary-drug treatment than during colestipol-niacin treatment (p < 0.003) or during treatment in which other possible binary combinations were given. The cholesterol content of very low-density-lipoproteins was lower and high-density-lipoprotein cholesterol levels higher during this phase than during the colestipol-niacin phase.
Conclusions: Colestipol, lovastatin, and niacin are mutually complementary in treating hypercholesterolemia. This regimen produces reductions in serum cholesterol levels similar to those associated with regression of atheromatous plaques in animal studies.
