Primary Outcome Measures
NameTimeMethod
Main Objective: The primary objective of the study is to determine if dabigatran and its metabolites are detectable in breast milk following oral administration to non-breast feeding mothers. <br><br>;Secondary Objective: The secondary objective is to determine dabigatran pharmacokinetics (Tmax, Cmax, t1/2, AUC) in maternal plasma and breast milk (if dabigatran is detectable in breast milk). <br>;Primary end point(s): To determine if Dabigatran is detectable in plasma and breast milk after it has been ingested by the mother. ;Timepoint(s) of evaluation of this end point: This will be measured at 0,1,2,5,7,10 hours after swallowing two 110mg capsules of <br>dabigatran.
Secondary Outcome Measures
NameTimeMethod
Secondary end point(s): If Dabigatran is detected:<br><br>Time course of dabigatran concentration in breast milk.<br><br>Time course of dabigatran concentration in maternal plasma.<br>;Timepoint(s) of evaluation of this end point: This will be measured across the 0,1,2,5,7,10 hours after swallowing two 110mg capsules of dabigatran.
