A long-term comparative trial of cerivastatin sodium, a new HMG-CoA reductase inhibitor, in patients with primary hypercholesterolemia.

Cerivastatin sodium, a synthetic and pure enantiomeric 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitor, is considered effective in the treatment of mild-to-moderate primary hyper-cholesterolemia (total cholesterol < or = 220-259 mg/dL) at a daily dose of 0.15 mg. We compared the efficacy and tolerability of a dosage of 0.3 mg/d with those of a dosage of 0.15 mg/d in patients with severe primary hypercholesterolemia (serum total cholesterol > or = 260 mg/dL). After a minimum of 4 weeks' lead-in with placebo, 73 patients with severe primary hypercholesterolemia were randomly assigned to receive either 0.15 or 0.3 mg of cerivastatin sodium once daily after the evening meal for 12 weeks. In 58 patients, the same drug was continued at a flexible dosage for an additional 36 weeks or longer to assess the long-term efficacy and tolerability of cerivastatin sodium. During the 12-week treatment period, serum total cholesterol levels decreased significantly from baseline in both dosage groups, but the percentage reduction was significantly greater in the 0.3-mg group (range, 24.4% to 25.6%) than in the 0.15-mg group (range, 19.4% to 21.6%). The percentage reduction in levels of low-density lipoprotein cholesterol, triglycerides, and apolipoprotein B and the percentage increase in levels of high-density lipoprotein cholesterol were significantly greater in the 0.3-mg group than in the 0.15-mg group. When the results for the 0.3- and 0.15-mg groups were combined, the percentage of change in serum lipid levels at 48 weeks remained as stable as at 12 weeks. No serious adverse reactions were observed. We concluded that the higher dose of cerivastatin sodium was more effective than the lower dose, with comparable tolerability, in the treatment of patients with severe primary hypercholesterolemia.
