Pharmacokinetic Interaction Between Rosuvastatin and Metformin in Healthy Korean Male Volunteers: A Randomized, Open-label, 3-period, Crossover, Multiple-dose Study

Although the Css,max of rosuvastatin was significantly influenced by coadministration with metformin, the degree of interaction seen was considered clinically insignificant, with no significant interaction observed in the other pharmacokinetic measures between the 2 drugs. These results imply that drug effects of rosuvastatin and metformin will also not be significantly influenced by coadministration of the 2 drugs. All treatments were well tolerated and no serious adverse events occurred. ClinicalTrials.gov identifier: NCT01526317.
