Lipid-Lowering Efficacy and Safety of a New Generic Rosuvastatin in Koreans: an 8-Week Randomized Comparative Study with a Proprietary Rosuvastatin

The problem of choice: original drug or generic? Emphasis on rosuvastatin

An increase in the life expectancy of the population and the number of polymorbid patients with a combination of two or more diseases in different age categories, including among young people, has led to a significant increase in the cost of medical care in the field of public health. The transition from original drugs to generic ones has become a common measure to contain these costs. While this is an important goal for healthcare systems around the world, the impact of this practice on patient outcomes needs to be carefully considered. In some cases, generics may represent a suitable alternative to branded products, but this is not always the case. In particular, studies have shown that changing the drug can negatively affect not only patients' adherence to treatment, but also clinical outcomes, and a subsequent increase in the total cost of treatment, therefore, the use of generics in clinical practice still causes caution and concerns on the part of both the doctor and the patient. Due to the high prevalence of dyslipidemia and hypercholesterolemia both worldwide and in Russia, in this review the problem of choosing an original drug or generic is described by the example of such a hypolipidemic agent as rosuvastatin. According to numerous studies, rosuvastatin is one of the most potent and widely prescribed statins. Considering that most of the clinically significant effects of this drug are demonstrated in relation to its original form, the review emphasizes the importance of prescribing the original drug rosuvastatin in routine clinical practice.

Assessing the Validity of the Criteria for the Extreme Risk Category of Atherosclerotic Cardiovascular Disease: A Nationwide Population-Based Study

Objective

To validate the criteria for the extreme risk category for atherosclerotic cardiovascular disease (ASCVD).

Methods

An observational cohort study of 35,464 individuals with established ASCVD was performed using the National Health Information Database. Incident myocardial infarction (MI), ischemic stroke, and death in patients with established ASCVD was investigated to validate the criteria for the extreme risk category of ASCVD defined as the presence of diabetes mellitus (DM), chronic kidney disease (CKD), and history of premature ASCVD.

Results

Among 35,464 patients, 77.97% of them were classified into the extreme risk group of ASCVD. A total of 28.10%, 39.61%, and 32.12% had DM, CKD, and a history of premature ASCVD, respectively. During a mean follow-up of 8.39 years, MI, ischemic stroke, and all-cause death were found in 3.87%, 8.51%, and 23.98% of participants, respectively. In multivariate analysis, patients with DM had higher risk for MI (hazard ratio [HR], 1.62; 95% confidence interval [CI], 1.45–1.81), ischemic stroke (HR, 1.39; 95% CI, 1.29–1.50), and all-cause death (HR, 1.52; 95% CI, 1.45–1.59) than those without DM. Patients with CKD had 1.56 times higher risk for MI, 1.12 times higher risk for ischemic stroke, and 1.34 times higher risk for death than those without CKD. However, the risk for MI, ischemic stroke, and all-cause death was not different between patients with and without a history of premature ASCVD.

Conclusion

DM and CKD, but not a history of premature ASCVD, could be considered as reasonable criteria of an extreme risk for ASCVD.
