Brief Summary

To find out if a drug called tapentadol administered by mouth safely relieves pain in children. Look at the amount of tapentadol in the blood after a single oral dose. Tapentadol oral solution for children is still being tested and is not yet registered. Tapentadol tablets are effective in treating both acute and chronic pain in adults. This trial will help to understand how tapentadol oral solution works in children.

Outcome Measures

Primary Outcomes (14)

• Pharmacokinetic Profile of Serum Concentrations of Tapentadol After a Single Dose of Tapentadol Oral Solution in Adolescents (Age 12 to Less Than 18 Years).

  Mean and Standard Deviation of Serum Concentrations of Tapentadol. Serum was analyzed by means of liquid chromatography coupled to tandem mass spectrometry with a lower limit of quantification (LLOQ) at 0.2 ng/mL.

  up to 15 hours

  Mean and Standard Deviation of Serum Concentrations of Tapentadol-O-glucuronide. Tapentadol-O-glucuronide is the metabolite of tapentadol. Metabolites are sometimes referred to as "breakdown products". The body alters the administered medication to a metabolite so that it can be more easily or quickly removed from the body.

  up to 15 hours

• Non-Compartmental Pharmacokinetic (PK) Parameter of Tapentadol Area Under the Concentration-Time Curve (AUC 0-15) After a Single Dose of Tapentadol in Adolescent Participants (Age 12 to Less Than 18 Years).

  Serum samples for pharmacokinetic analysis were obtained using frequent sampling techniques in participants 12 years to less than 18 years of age. Serum samples (frequent sampling) were drawn at 0.25, 0.5, 1, 2, 4, 6, 11, and 15 hours. The Area Under the Curve (AUC) from dose to 15 hours (AUC 0-15) is a summary measure of data from each pharmacokinetic blood sample taken over the 15 hour time period. The area is that below the line fitted to the data points.

  up to 15 hours

• Non-Compartmental Pharmacokinetic (PK) Parameter: Cmax (Maximum Concentration) of Tapentadol After a Single Dose of Tapentadol in Adolescents (Age 12 to Less Than 18 Years).

  Serum samples for pharmacokinetic analysis were obtained using frequent sampling techniques in participants 12 years to less than 18 years of age. Serum samples (frequent sampling) were drawn at 0.25, 0.5, 1, 2, 4, 6, 11, and 15 hours. The concentration of tapentadol (active drug) is assessed during absorption and distribution. The maximum concentration is derived from the Area Under the Curve, from dose to 15 hours (AUC 0-15). It is the highest amount of active drug observed in the blood sample

  up to 15 hours

• Non-Compartmental Pharmacokinetic (PK) Parameter: Time to Maximum Concentration (Tmax) of Tapentadol After a Single Dose of Tapentadol in Adolescents (Age 12 to Less Than 18 Years).

  Serum samples for pharmacokinetic analysis were obtained using frequent sampling techniques in participants 12 years to less than 18 years of age. The time to maximum concentration is derived from the area under the curve from dose to 15 hours (AUC 0-15). The Tmax is the time after dosing at which the maximum concentration of the tapentadol (active drug) occurs. Serum samples (frequent sampling) were drawn at 0.25, 0.5, 1, 2, 4, 6, 11, and 15 hours.
