Primary Outcome Measures

Name	Time	Method
Cmax of Buprenorphine.	Blood samples collected over a 144 hour period.	Bioequivalence based on Buprenorphine Cmax (maximum observed concentration of drug substance in plasma).
AUC0-t for Buprenorphine.	Blood samples collected over a 144 hour period.	Bioequivalence based on Buprenorphine AUC0-t (area under the concentration-time curve from time zero to time of last measurable concentration).
AUC0-inf for Buprenorphine.	Blood samples collected over a 144 hour period.	Bioequivalence based on Buprenorphine AUC0-inf (area under the concentration-time curve from time zero to infinity).
