Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study consists of two test groups.
1. A reservoir patch system containing 1% Tocopheryl Phosphate Mix (TPM) and 5% Oxycodone and;
2. A matrix patch system containing 40mg Tocopheryl Phosphate Mix (TPM) and 200mg Oxycodone.
Subjects will be randomly assigned to receive only one of the above treatments.
Both groups will receive the study drug in their allocated patch form containing 200mg Oxycodone. The 200mg will be divided into two 100mg patches applied to each upper outer thigh region. The patch will remain in place for 23 hours and 30 minutes from the time of application and a new patch applied 30 minutes later. This will occur daily, for 10 days, for all volunteers.
The matrix patch is made of a solid film polymer whereas the reservoir patch is made of TPM gel enclosed in a semi-permeable membrane.

Outcomes
Primary outcome [1] 253006 0
To compare the relative bioavailability of a reservoir and matrix patch system containing TPM after repeated application.
Timepoint [1] 253006 0
Blood samples will be collected within 15 minutes prior to dosing (0hr) and 6 hourly from 0 to 240 hrs and then 8 hourly from 240 to 408 hours post-dose.
Secondary outcome [1] 257779 0
To evaluate the tolerability and safety of oxycodone in novel formulations containing TPM after repeated application.
Timepoint [1] 257779 0
