For example, have any studies been conducted to support the use of Vivtrol in the treatment of a specific substance over the use of Suboxone, used to treat narcotics dependence? Second, what is the half life of Vivitrol? Thank you.

Suboxone is made up of two parts, buprenephrine and naltrexone. Naltrexone is the opioid blocker while the buprenephrine is the opiate. Vivitrol is just a fancy name for an injection of naltrexone. In my opinion, naltrexone is far safer because it blocks cravings as well as opiates to prevent relapse from occurring without being addictive. The problem however is that it does not help with any withdrawal symptoms and should only be used after the withdrawal period. The reason many resort to long term suboxone use is to prevent withdrawal only to find out that they must either remain on suboxone indefinitely or prepare for a very slow taper off suboxone with hopes of minimal discomfort. I hear it has been done but in my experience I have not been so fortunate.
If I could do it over I would have tapered off my drug of choice with suboxone for a short period, less than 3 weeks, then switch to naltraxone to prevent my cravings and chance of relapse until I felt completely secure in my recovery plan. Best of luck to you! If you decide to do a maintenance plan with suboxone just be prepared that it will take a lot of courage and strength on your part. Some people say it has saved their life so please remember this is only based on my experience!

Not too fimilar with naltrexone but I did find the half life info which is:
The elimination half life of naltrexone following Vivitrol administration is 5 to 10 days and is dependent on the erosion of the polymer. The elimination half life of 6β-naltrexol following Vivitrol administration is 5 to 10 days.
I guess the nice thing about naltrexone is the injection lasts a month, so you don't have to take it everyday like Suboxone. Don't know much else about it.
