INTRODUCTION: The ROsulord® sAfety for patients with Dyslipidemia study (ROAD study) in the Republic of Korea investigated the safety and efficacy of rosuvastatin in routine clinical practice. METHODS: This non-interventional, multicenter, prospective, observational study was conducted over a period of approximately 4.6 years and involved 14,243 participants. During this study, we assessed the adverse events, changes in laboratory test results, and efficacy endpoints associated with rosuvastatin use. RESULTS: The findings revealed a notably low adverse event rate of 1.63%, indicating a favorable safety profile for rosuvastatin in the management of dyslipidemia. Importantly, no clinically significant incidences of statin-associated myopathy, hepatotoxicity, or diabetes were observed during the study period. Moreover, this study demonstrated significant improvements in lipid profiles among patients receiving rosuvastatin treatment, with a reduction in total cholesterol, low-density lipoprotein cholesterol, and triglyceride levels. These improvements contributed to a lower cardiovascular risk in the study population. CONCLUSION: Overall, these findings suggest that rosuvastatin is safe and effective in managing dyslipidemia in real-world clinical settings, providing clinicians with valuable insights into the benefits and risks associated with statin therapy in this patient population.
