Drug-drug Interaction Study(Lobeglitazone, Warfarin)

Open Label, Randomized, Crossover Study to Evaluate a Pharmacokinetic Drug Interaction Between Lobeglitazone and Warfarin in Healthy Subjects

The purpose of this study is to evaluate a pharmacokinetic drug interaction between lobeglitazone and warfarin in healthy subjects.

From day 1 to day 12, lobeglitazone 0.5mg is administered daily to Group 1 subjects during period 1. Then on day 5,warfarin 25mg is co-administered Group 1 subjects at period 1. After 10 day-break, warfarin 25mg is administered Group 1 subjects at period 2. On period 2, lobeglitazone is not administered.

Group 2 is administered in reverse order.
