Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Extended-release Injectable Naltrexone (XR-NTX) | Monthly XR-NTX (380 mg) Subjects randomized to XR-NTX will receive one intramuscular gluteal injection (in accordance with the FDA approved label/package insert) of 380 mg of NTX for extended-release injectable suspension at study entry (in the hospital) and 1, and 2 months later (outpatient in the primary care clinic), alternating buttocks.~Extended-release injectable naltrexone (XR-NTX): injectable naltrexone | 2 | 123 | EG000 |
| Group 2 | Oral Naltrexone (PO-NTX) | Daily PO-NTX (50 mg, up to 100 mg if heavy drinking continues) Subjects randomized to PO-NTX will receive a study prescription (first one in the hospital)(fillable only at the medical center research pharmacy and prepared by the research pharmacist) for a 1-month supply of oral NTX to be taken once daily- 25 mg a day for 3 days, then 50 mg a day. If the subject has a prior history of taking PO-NTX and tolerating it well, the participant may be started at 50 mg. The dose may be increased to 100 mg daily for any participant who continues to have heavy drinking.~Oral naltrexone (PO-NTX): oral naltrexone | 3 | 125 | EG001 |
