Suboxone: It’s a Fine Mess You’ve Made

Weiss, R., et al. (2012). Adjunctive counseling during brief and extended buprenorphine-naloxone treatment for prescription opioid dependence. Archives of General Psychiatry, 68 (12), 1238-1246.
This is an interesting article and on first pass, it seems like a reasonable look at the relative merits of medication management with buprenorphine-naloxone (Suboxone) v. the same with an additional counseling component. But on further inspection, the spin on the results is an unabashed marketing of Suboxone to primary care docs. First, and foremost, the results are simply atrocious. The study had 2 phases: a two week “treatment lite” version (2 weeks of meds with a 2 week taper off the med followed by a 7 week follow up) and an up to 24 week more intensive regimen (12 weeks of meds followed by a 3 week taper and a 7 week follow up). In the first phase, only 6.6% of participants achieved successful outcomes; in the second phase, only 8.6% achieved a successful outcome. Holy Cow! The additional counseling mattered not: no differences in outcome between conditions. But before I get to that, and there is likely a pretty good reason for it, let’s address the spin on this study.
In the second phase, following 12 weeks of the meds (of course you know this an opioid agonist that approximates but does not offer the full package of actual opioid use because of the addition of a one quarter antagonist), there was a 49.2% successful outcome which all but evaporated after the med was tapered off. So the spin is that as long as you keep prescribing the Suboxone, nearly half of patients will successfully stay off prescription opioids. But if you stop, nearly all of those who benefit will ultimately start using again. So Suboxone, in essence, and without saying it directly, is promoted as a life-long treatment for opioid addiction that any physician can do in primary practice. A scary thought to be sure, and certainly a conclusion that benefits you know who. That’s the spin. But what won’t be in the sound bites here is that the medication management condition included weekly appointments with docs and weekly discussion of addiction, abstinence, and other psychiatric and substance abuse issues as well as the recommendation of self help groups. So the medication management condition already included a counseling component, although a less intensive one—a 20 minute meeting as opposed to the 60 minute meetings in the counseling condition. It is not likely that primary care physicians in the real world would every do the medication management component of the treatment and would wind up just prescribing the Suboxone, which is likely the bottom line message here.
Now, I am not saying that counseling added anything better because it didn’t. It seems like the counseling was pretty much the traditional, psychoeducational medical model, 12 step variety with a skill building component around life skills and relapse prevention. It just didn’t add much to what the doc provided and perhaps was seen as superfluous by the patient after talking to the doc and getting the drug. In essence it was counseling lite (by a doc who is giving you drugs) vs. a more intensive counseling experience. I wonder what giving the drug v. therapy would have done. I don’t think it was a very good effort to show what therapy can provide a person with an opioid addiction .
Several take home points: first of all opioid addiction (oxycodone, hydrocodone, hydromorphone, morphine, codeine, propoxyphene, etc), virtually created by free prescribing practices of primary care docs and anesthesiologists for pain etc, promoted heavily by drug companies is perhaps the mother of all addictions in terms of difficulty to treat. It exceeds heroin addiction in scope by at least 20 times. Perhaps it is the ultimate irony that the treatment advocated is to be administered by the same primary care docs who got us into this mess to start with. So the pharmaceutical industry has created this monster problem and now has a solution for it. I hope that we can figure out a better way than keeping a person on Suboxone. Because, besides the less than exemplary results, 83% experienced 1 or more adverse events in Phase 1 and 60% in Phase 2 (most common were headache and constipation). It is interesting that percentages of all the side effects are presented until we get to the “serious adverse events (SAE).” In Phase1, there were 12 SAEs (just 2 weeks of med treatment) or 1.8% experienced an SAE but when the med treatment continued for 12 weeks, 6.7% of patients experienced a severe adverse reaction. So the risks increase as time on the meds increase.
It is a complicated picture of a very difficult problem. Call me jaded but it is hard for me to not to see this article (whose authors have many ties to pharmaceuticals) as purely a marketing effort.
That’s my take.
