Exclusion Criteria

• The participant's parent(s) or legal guardian(s) is an employee of the investigator or trial site, with direct involvement in this trial or other trials under the direction of that investigator or trial site, or the subject, or subject's parent(s), or legal guardian(s) is a family member of the employees or the investigator.
• Participant has been previously exposed to tapentadol.
• Participant has received an experimental drug or used an experimental medical device within 28 days before allocation to study medication, or within a period less than 10 times the drug's half-life, whichever is longer.
• Concomitant participation in another clinical trial with an experimental drug or experimental device for the duration of this trial.
• Participant has undergone brain surgery.
• Participant has undergone a surgery that is expected to affect the absorption of tapentadol (e.g., to the gastrointestinal tract).
• Participant has a history or current condition of any one of the following:
- Seizure disorder.
- Traumatic or hypoxic brain injury, brain contusion, stroke, transient ischemic attack, intracranial hematoma, post-traumatic amnesia, brain neoplasm, or episode(s) of unconsciousness of more than 24 hours.
• Participant has a history or current condition of any one of the following:
- Moderate to severe renal impairment.
- Moderate to severe hepatic impairment, congestive hepatopathy, or hepatic portosystemic shunting.
- Clinically relevant abnormal pulmonary function or clinically relevant respiratory disease.
• Participant has signs or symptoms of congestive heart failure (e.g., requiring more than minimal inotropic support, an abnormal lactic acid value greater than 2-times upper limit of normal), or hemorrhagic disorder following surgery.
• Minimal inotropic medication is defined as:
- Dopamine less or equal to 5 microgram/kg per minute.
- Epinephrine less or equal to 0.03 microgram/kg per minute (but not both dopamine and epinephrine).
- Milrinone less or equal to 0.5 microgram/kg per minute or less.
• Participant has a concomitant disease or disorder (e.g., endocrine, metabolic, neurological, or psychiatric disorder, or a febrile seizure or paralytic ileus) that in the opinion of the investigator may affect or compromise participant's safety during the trial participation.
• Participant has cognitive or developmental impairment such that trial participation may affect or compromise the participant's safety, or the participant's ability to comply with the protocol requirements (as appropriate for the subject's age), in the investigator's judgment. Otherwise, participant's with cognitive or developmental impairment may be enrolled in the trial.
• Participant has a clinically relevant history of hypersensitivity, allergy, or contraindication to tapentadol (or ingredients).

Participant has:
• Clinically relevant abnormal 12-lead ECG.
• Signs of pre-excitation syndrome.
• Corrected QT (QTcF) interval >460 ms. Subjects may be allocated to IMP with values >460 ms if, in the investigator’s opinion, the value is a consequence of cardiac surgery and is not considered clinically significant.
• Participant has clinically relevant abnormal lab values from a sample obtained postoperatively and prior to allocation to study medication. The following specifications will apply:
- Aspartate transaminase or alanine transaminase is greater than 2.5-times upper limit of normal.
- Total bilirubin is greater than 2
