Background Despite their efficacy, statin-related adverse events (AEs) may interfere with statin treatment and contribute to negative outcomes in patients with cardiovascular diseases. In this study, we evaluated the safety and effectiveness of pravastatin in Korea.
Methods Pooled data were collected from four multicenter prospective observational studies conducted in Korea between 2011 and 2020. Finally, 7,334 and 2,022 participants were included in the safety and effectiveness analyses, respectively. Overall safety, particularly muscle-related, incidence of new-onset diabetes mellitus (DM), changes in fasting plasma glucose and hemoglobin A1c level, achievement of target low-density lipoprotein cholesterol (LDL-C) level, and changes in LDL-C level were analyzed.
Results At week 24, after 20 or 40 mg pravastatin treatment, safety results showed that AEs and adverse drug reactions (ADRs) were 8.7% and 1.3%, respectively, and that muscle-related AEs and ADRs were 0.5% and 0.3%, respectively, with no statistically significant difference in risk factors for statin-associated muscle symptoms. No patients developed DM during the study period. Additionally, at week 24, the achievement rates of target LDL-C levels were 87.9%, 78.4%, 57.8%, and 11.6% in low-, moderate-, high-, and very high-risk groups, respectively.
Conclusion This study found that 20 or 40 mg pravastatin had minimal side effects and was safe for use in real-world clinical settings in Korea. Specifically, these doses effectively achieved the target LDL-C levels in patients with dyslipidemia in low-, moderate-, and high-risk groups for atherosclerotic cardiovascular disease (ASCVD). These results demonstrate that pravastatin can be safely administered continuously to patients with low-, moderate-, and high-risk ASCVD in a real-world clinical setting.
