Description of intervention(s) / exposure
The study consists of four test groups.
1. Daily application of a matrix patch system containing 40mg Tocopheryl Phosphate Mix (TPM) and 200mg Oxycodone applied to the same site on the upper right or left thigh every day for 14 days.
2. Daily application of a matrix patch system containing 40mg TPM and 200mg Oxycodone, rotating the application between two sites on the upper right or left thigh every day for 14 days.
3. Daily application of a matrix patch system containing 20mg TPM and 100mg Oxycodone applied to the same site on the upper right or left thigh every day for 14 days.
4. Weekly application of a matrix patch system containing 40mg TPM and 200mg Oxycodone to the same site on the upper right or left thigh for 2 weeks.
