Summary:

      The primary objective of this trial is to investigate the relative Bioavailability (BA) of
      tablet formulation of Dabigatran etexilate (DE) with and without co-administration of
      rabeprazole in healthy male subjects.

      The secondary objective is the evaluation and comparison of several pharmacokinetic
      parameters between the treatments.
    

Eligibility criteria:

        Inclusion Criteria:

          -  Healthy male subjects according to the investigator's assessment, based on a complete
             medical history including a physical examination, vital signs (blood pressure (BP),
             pulse rate (PR)), 12-lead electrocardiogram (ECG), and clinical laboratory tests

          -  Age ≥ 20 and ≤ 40 years at informed consent

          -  Body mass index (BMI) of 18 ≥ and ≤ 25 kg/m2 at screening

          -  Signed and dated written informed consent prior to admission to the study in
             accordance with Good Clinical Practice (GCP) and local legislation

        Exclusion Criteria:

          -  Any finding in the medical examination (including blood pressure (BP), pulse rate (PR)
             or electrocardiogram (ECG)) is deviating from normal and judged as clinically relevant
             by the investigator

          -  Measurement of systolic blood pressure (BP) outside the range of 90 to 140 mmHg,
             diastolic blood pressure outside the range of 50 to 90 mmHg, or pulse rate (PR)
             outside the range of 45 to 90 bpm at screening

          -  Any laboratory value outside the reference range before administration of DE that the
             investigator considers to be of clinical relevance

          -  Any evidence of a concomitant disease judged as clinically relevant by the
             investigator

          -  Any relevant bleeding history considered by the investigator

          -  Any history or evidence of blood dyscrasia, haemorrhagic diathesis, severe
             thrombocytopenia, cerebrovascular haemorrhage, bleeding tendencies associated with
             active ulceration or overt bleeding of gastrointestinal, respiratory or genitourinary
             tract or any disease or condition with haemorrhagic tendencies

          -  Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic,
             immunological or hormonal disorders

          -  Any history of hypochlorhydria or achlorhydria

          -  Cholecystectomy and/or surgery of the gastrointestinal tract that could interfere with
             the pharmacokinetics of the trial medication (except appendectomy and simple hernia
             repair)

          -  Planned surgeries within four weeks following the end-of trial examination

          -  Diseases of the central nervous system (including but not limited to any kind of
             seizures or stroke), and other relevant neurological or psychiatric disorders

          -  History of relevant orthostatic hypotension, fainting spells, or blackouts

          -  Chronic or relevant acute infections

             medication or its excipients)

          -  Use of drugs within 30 days prior to administration of trial medication if that might
             reasonably influence the results of the trial (incl. QT/QTc interval prolongation)

          -  Participation in another trial where an investigational drug has been administered
             within 60 days prior to planned administration of trial medication, or current
             participation in another trial involving administration of investigational drug

          -  Smoker (more than 10 cigarettes or 3 cigars or 3 pipes per day)
