Effect of Atorvastatin and Rosuvastatin on the Glycemic Control in Patients with Type II Diabetes Mellitus: A Comparative, Randomized, Double-Blind Study

Objectives: To compare the effects of atorvastatin and rosuvastatin in type II diabetes mellitus (T2DM) patients with dyslipidemia.

Materials and Methods: Eighty patients with history of T2DM of more than 3 months duration, glycated hemoglobin <7%, dyslipidemia, and normal electrocardiogram were included in the randomized double‑blind trial. The patients received either tablet atorvastatin 20 mg or rosuvastatin 10 mg once a day along with metformin and glimepiride twice daily orally. Patients were evaluated by the change in estimated average glucose (eAG), lipid profile, and incidence of adverse drug reactions (ADRs).

Results: Rise in fasting blood sugar (FBS), postprandial blood sugar, and eAG were significant in the atorvastatin group as compared to the rosuvastatin group where there was a significant increase only in FBS levels. Changes in lipid parameters and incidence of ADR were similar in both the groups.

Conclusion: Rosuvastatin can be preferred to atorvastatin in T2DM with dyslipidemia due to less variation in the blood sugar parameters, effective control over lipid profile, pleiotropic effects, and less microsomal interactions.
