This was a randomized, phase II, double-blind, multicenter pilot study comparing immediate-release oral DAM, slow-release oral morphine and oral methadone administered twice a day during 10 days. Forty-five heroin-dependent patients were randomly assigned to these three treatment groups in an inpatient regime. Patients were stabilized with a mean of 350 mg (SD = 193) of immediate-release oral DAM, 108 mg (SD = 46.2) of slow-release oral morphine and 40 mg (SD = 17.9) of methadone. No statistically significant differences were found between any studied medication in clinical outcome. Neither patients nor clinicians were able to identify the administered medication. This study shows the feasibility of double-blind clinical trials using b.i.d. immediate-release oral DAM allowing further phase III clinical trials in the process of introducing oral DAM as a medication for heroin-dependent patients not responding to standard maintenance treatments.
