A Drug-Drug Interaction Study to Study the Effect of AZD1981 on Warfarin

A Phase I, Open Label, Randomised, Parallel Group Study of Repeated Oral Doses of AZD1981 (100 mg Twice Daily and 400 mg Twice Daily) for Two Weeks and Single Doses of Warfarin (25 mg) to Evaluate the Pharmacokinetic Interaction of AZD1981 and Warfarin and the Effect of AZD1981 on Warfarin Pharmacodynamics in Healthy Male Volunteers

Design outcomes

Primary

MeasureTime frame
Pharmacokinetics for (R)- and (S)-Warfarin, respectively measured by Cmax and Area Under the Curve (AUC)PK sampling will be performed regularly from Day 1 to Day 22

Secondary

MeasureTime frame
Explore possible changes in the anticoagulative activity of Warfarin measured by INR .Will be performed at screening and at all visits during the study period.
Pharmacokinetics for AZD1981 measured by AUCτ, Css,max, tmax,ss and CLss/FPK sampling will be performed regularly from Day 15 to Day 22.
