Cmax (Maximum Measured Concentration of Total Dabigatran in Plasma)

时间窗: At 1 hour (h), 2 h, 4 h, 6 h, and 10 h after single administration of dabigatran etexilate

Cmax (maximum measured concentration of total dabigatran in plasma). Endpoint can only be calculated for single dose patients. For multiple dose patients the time points do not allow calculation of Cmax (no profile, only one measurement after selected doses, refer to primary outcome no. 1 and 2).

时间窗: At 1 hour (h), 2 h, 4 h, 6 h, and 10 h after single administration of dabigatran etexilate

tmax (time from dosing to maximum measured concentration of total dabigatran in plasma). Endpoint can only be calculated for single dose patients. For multiple dose patients the time points do not allow calculation of tmax (no profile, only one measurement after selected doses, refer to primary outcome no. 1 and 2).

AUC0-tz (area under the concentration time curve of the total dabigatran in plasma over the time interval 0 up to the last quantifiable data point). Endpoint can only be calculated for single dose patients. For multiple dose patients the time points do not allow calculation of AUC0-tz (no profile, only one measurement after selected doses, refer to primary outcome no. 1 and 2).

Cmax (Maximum Measured Concentration of Free Dabigatran in Plasma)

时间窗: At 1 hour (h), 2 h, 4 h, 6 h, and 10 h after single administration of dabigatran etexilate

Percentage of Patients With Incidence of Any Bleeding Events (Major, Clinically Relevant Non-major (CRNM) and Minor) During the Treatment Period.

时间窗: Up to 6 days

Major: Fatal bleeding, Clinically overt bleeding associated with decrease in haemoglobin of at least 2 g/dL in 24-h-period,bleeding that was retroperitoneal,pulmonary,intracranial,or otherwise involved the central nervous system,bleeding that required surgical intervention in an operating suite. CRNM: Overt bleeding for which a blood product was administered \& which was not directly attributable to the patient's underlying medical condition,bleeding that required medical or surgical intervention to restore haemostasis,other than in an operating suite. Minor: Any overt or macroscopic evidence of bleeding that did not fulfil the criteria for either major bleeding or CRNM bleeding. For multiple dosing,all events with an onset date after the date of first dose until the end of trial treatment including 3 days after the last treatment and for single dosing,all events with an onset during the 48-h-period after study medication intake were assigned to the on-treatment period.
