A clinical study to compare safety and efficacy of two brands of buprenorphine (XPRENOR and SUBUTEX) in patients who are opioid dependent.

A Phase II, randomized, multi-centric, open-label, two arm study to determine the safety profile and establish the efficacy of Xprenor® (buprenorphine oral lyophilisate) in comparison with Subutex® (buprenorphine hydrochloride) in opioid dependent patients
