Comparison of the Efficacy of Rosuvastatin 5 mg and 10 mg in Patients of Type 2 Diabetes Mellitus With Dyslipidemia

Objectives We did this study intending to compare the efficacy of rosuvastatin 5 mg and 10 mg in patients of type 2 diabetes mellitus with dyslipidemia by validating their effect on lipid profile and the side effects. Methodology This study was carried out at the outpatient department of a tertiary care hospital in Multan. Three hundred patients of both genders were included. The research approach employed a parallel-controlled, randomized study. After taking relevant history and physical examination, each patient's fasting venous blood samples were taken and sent to the institutional laboratory to analyze glycated hemoglobin (HbA1c), baseline lipid levels for cholesterol, triglycerides, low-density lipoprotein (LDL), very-low-density lipoprotein (VLDL), and high-density lipoprotein (HDL). Patients were divided into two groups based on the drug administered. One group was prescribed rosuvastatin 5 mg, and the other group was prescribed rosuvastatin 10 mg. Patients were followed up after six months to record the latest lipid profile. Data analysis was done through SPSS version 24. Results Patients in the two groups had similar lipid levels to start with. After six months of therapy, total serum cholesterol, triglycerides, and LDL-C were reduced to statistically significant levels in group two compared to group one. However, both groups showed a similar increase in serum levels of HDL-C. Patients treated with 10 mg rosuvastatin showed a slight decrease in BMI. Nine patients treated with 10 mg rosuvastatin reported myalgias compared to only one patient treated with a dose of 5 mg (p<0.005). Conclusion Our study concludes that both 5 mg and 10 mg of rosuvastatin exhibit the antihyperlipidemic effect, but high doses are associated with more side effects. Therefore, physicians should be aware of dose titration related to statins as it will ultimately lead to reduced cardiovascular mortality.
