In a 2-stage, placebo-controlled, Phase 2 dose-ranging trial evaluating the
new statin rosuvastatin in men and postmenopausal women with hypercholeste
rolemia, the agent was found to reduce low-density lipoprotein cholesterol
(LDL-C) levels in a dose-related manner. With each doubling of the rosuvast
atin dose (1, 2.5, 5, 70, 20, 40, and 80 mg/day), there was an additional 4
.5% reduction in LDL-C. Reductions in LDL-C were statistically significant
across all doses and ranged from 35% to 65%. The latter percent reduction s
urpasses the maximal reductions reported for all other statins when used fo
r monotherapy and suggests that rosuvastatin might enable more patients wit
h hypercholesterolemia to achieve target LDL-C levels. Across all doses, th
e new statin also had favorable effects on of:her lipid parameters and was
well tolerated, with the incidence of adverse events similar to placebo.
