Participants were inducted onto buprenorphine/naloxone sublingual tablets during the first week of study participation. The dose was titrated from bup/nal 8mg to bup/nal 16mg in three days where it will remain until the last day of week 8. The 7-day discontinuation of buprenorphine-naloxone on week 9 was 12mg, 10mg, 8mg, 6mg, 4mg, 2mg, 2mg and stopped. Memantine 5mg in the morning was started on week 2. The dose was titrated on a twice a day schedule until the target dose of 30 mg/day was achieved by week 4. The medication was discontinued over a one-week period on week 13. Patients received a 7-day supply of their medication each week.
