Abstract

Background: While randomized controlled trials provide useful information about drug safety and efficacy, they do not always reflect the observed results in the real world. The prospective, observational, non-comparative trial in South Korea was designed to evaluate the efficacy and safety of pitavastatin in clinical practice in 28,343 patients.

Methods: This study was conducted in 893 facilities in Korea from April 2, 2012 to April 1, 2017. This study was designed to administer 1, 2, or 4 mg pitavastatin to patients with hyperlipidemia at the age of 20 or older for at least 8 weeks.

Results: For 126 days of mean duration of administration of pitavastatin, the % change of low density lipoprotein cholesterol indicated a dose dependent reduction: -23.4%, -29.1%, and -35.2% in the 1, 2, and 4 mg groups, respectively in patients who have not been treated with lipid lowering medications prior to study. Only 1.74% (492/28,343) of pitavastatin-treated patients experienced adverse events, of which 0.43% (123/28,343) were adverse drug reactions. Less than 1% of patients experienced the grade 2 or more toxicity (Common Terminology Criteria for Adverse Events v4.03) in alanine aminotransferase, aspartate aminotransferase, serum creatinine, and serum creatine phosphokinase. Although there were no rhabdomyolysis in 28,343 patients, 0.04% of patients had been reported pitavastatin-related musculoskeletal disorders.

Conclusion: Overall, this observational study showed that pitavastatin was well tolerated and effectively modified the lipid profile, reducing cardiovascular and cerebrovascular risk in Korean patients with hypercholesterolemia in the real world.
