Objective: The aim of this study was to investigate whether a new generic rosuvastatin is non-inferior to a proprietary one in terms of lipid-lowering efficacy. We also evaluated its non-lipid effects including adverse events.
Methods: One-hundred and fifty-eight patients with cardiovascular risks requiring pharmacological lipid-lowering therapy were screened. After a 4-week run-in period, 126 individuals who met the lipid criteria for drug therapy were randomly assigned to receive the new generic or proprietary rosuvastatin 10 mg daily for 8 weeks. The primary outcome variables were low-density lipoprotein-cholesterol (LDL-C) reduction and LDL-C target achievement. Hematological and biochemical parameters and adverse events were assessed.
Results: After 8 weeks of drug treatment, the mean percentage change in LDL-C was not different between the groups (-45.5%±19.9% and -45.1%±19.0% for generic and proprietary rosuvastatin, respectively; p=0.38). The LDL-C target achievement rate was similar between the groups (75.0% and 77.1% for generic and proprietary rosuvastatin, respectively; p=0.79). The percentage change in the other lipid profiles was not significantly different. Although generic- and proprietary rosuvastatins modestly affected creatine kinase and blood pressure, respectively, the changes were all within normal ranges. Incidence of adverse events did not differ between the receivers of the 2 formulations.
Conclusion: The new generic rosuvastatin was non-inferior to the proprietary rosuvastatin in terms of lipid-lowering efficacy. The rosuvastatin formulations did not exhibit clinically significant non-lipid effects with good safety profiles. Our study provides comprehensive data regarding 2 rosuvastatin formulations in East Asian subjects.
