NCT03770234

Brief Summary

The purpose of the study was to investigate the pharmacokinetics (i.e. the uptake, distribution and elimination from the body) of dermally applied buprenorphine during and after different application periods, i.e., a 96-hour and a 72-hour application of the Transtec (Registered Trademark) patch (release rate 35 micrograms per hour \[µg/hour\]). In the Transtec summary of product characteristics (prescribing information for the physician), the wearing time per patch is restricted to three days (72 hours) after which the patch has to be replaced. However, market experience has shown that the Transtec patches are sometimes worn for a period longer than three days, i.e. they sometimes happen to be only replaced every four days. There was currently no data available as how to evaluate this longer wearing period.

Eligibility Criteria

  • Participation in another clinical study within three month prior to the start of this study (exception: characterization of metabolizer status).
  • Blood donation (more than 100 milliliters) within three month prior to the start of this study.

  • Evidence of alcohol, medication or drug abuse.
  • Positive Naloxone challenge test.
  • Positive drug abuse screening test.
