Buprenorphine: Current Practices

NCSAM

I just got back from the NC Society of Addiction Medicine annual conference. (Yes, I’ve been to several conferences lately.) One of the sessions I attended was a lively discussion of the current practices in office-based prescribing of buprenorphine, for opioid addiction.

The session was run by two experienced, knowledgeable addictionologists, who mediated topics and shepherded the dialogue. One physician works in North Carolina and the other in Tennessee. The room was packed with at least fifty people, most of us doctors who prescribe buprenorphine for addiction.

Deliberations were collegial but we didn’t agree on all issues, of course. Dissenting opinions were respected and debated.

The first topic I can recall was about how often buprenorphine patients need to be seen. Most practitioners agreed that new patients needed to be seen at least weekly initially. As stability develops, we gradually extend the time between visits to one month. One doctor opined that no patient should be allowed to go any more than one month between physician visits. When the moderator asked if anyone disagreed, I raised my hand, and the moderator asked me to explain.

With some trepidation, I told the audience that I had a super-stable group of patients in my practice. I inherited most of them from another physician who was one of the first in the area to prescribe buprenorphine. This group of patients all have over five years of stable and relapse-free recovery. A few have been in stable recovery for nearly ten years. These people work, and have happy and productive lives.

So yes, I do allow these patients to go two months between visits.

No one booed or hissed me, but I got the feeling I’m doing something with my patients outside the realm of normal for most doctors prescribing buprenorphine. Thankfully, the moderator made the point that we should use our clinical judgment and adjust treatment to best fit each situation, which made me feel better.

I was mulling this over later, and maybe I do have an unusual group of patients, who have been stable on MAT for so long. Some of these patients elected to stay on sublingual buprenorphine because they are doing so well on it, and they fear relapse if they taper off of it. Others plan to stay on buprenorphine because they developed addiction as a complication of chronic pain treatment. Happily, the buprenorphine works as well for their pain as it does for their addiction, so we get the two birds with the one stone.

There’s another unusual thing about these super-stable patients: almost all of them are deeply involved in 12-step recovery. Many were in Alcoholics Anonymous prior to their opioid addiction. They developed addiction to opioid pain pills after receiving prescription opioids for an acute or chronic pain condition. Once they started on buprenorphine to treat the opioid addiction, they continued going to Alcoholics Anonymous (a few go to Narcotics Anonymous).. Other patients didn’t start going to AA until after they entered MAT on buprenorphine.

I’ve had many people write comments to my blog, furious when I even mention 12-step recovery and MAT in the same sentence. But I have living proof in my practice of multiple patients on medication-assisted treatment of opioid addiction who have been able to make 12-step programs work for them.

Getting back to the conference…we spent much time discussing the monoproduct buprenorphine versus the combination product buprenorphine/naloxone. All of us agreed there’s a need for caution with prospective patients who insist they can take only the monoproduct (this is the equivalent of the brand name Subutex), because it does have a higher street value than the combination product.

Of course, there are people who inject the combination product (Suboxone film, Zubsolv, etc.), but overall, people seeking to inject buprenorphine are much more likely to prefer plain buprenorphine. Black market prices are higher for the monoproduct than the combination product, underscoring the preference for monoproduct.

One outspoken doctor said the monoproduct should rarely if ever be prescribed. Another doctor echoed my feelings on the matter when he said something to the effect that some patients really do have a bad reaction to the naloxone in the combination products, and if we are cautious, we can prescribe the monoproduct. However, the general opinion was that financial reasons weren’t sufficient to take the risk of prescribing the monoproduct.

I disagree with that, but kept quiet, already feeling like maybe I’m a bit too liberal.

I have had patients, stable on a buprenorphine combination product (usually brand name Suboxone films), who suddenly lost their health insurance. If such patients had negative drug screens for years, and no history of intravenous use, I switched them to the generic monoproduct because it’s the cheapest buprenorphine product on the market. These patients could not have stayed in treatment if I’d made them stay on the much more expensive brand names. Most of those patients prefer the films, and when they got new insurance, asked to switch back to the films.

I did not suspect these patients would sell their medication for profit. You have to know them, but these patients had stable jobs and no leanings toward criminality. And I am by no means a gullible person.

Since then, a generic combination product came onto the market. Still more expensive than the monoproduct, it’s less expensive than all the name brands.

Next we discussed how to deal with patients who say they are allergic to naloxone, and thus can’t take the combination product (Suboxone, Zubsolv) but only the monoproduct (Subutex).. Patients usually don’t mean an actual allergy, but rather intolerance to naloxone. These patients report headache, nausea, etc. when they ask their physician to prescribe the monoproduct. Of course, this raises suspicion with physicians that such patients plan to misuse the medication by injecting or snorting.

Should physicians just accept what patients say at face value, or should we say sorry, I only prescribe buprenorphine in combination with naloxone? After all, there’s no way to “prove” a headache or nausea. There’s no test we can order that will give any useful information. One doctor said he sent such patients to a neurologist for evaluation of the headache, or to a gastroenterologist to decide the cause of nausea. He says most patients fail to follow through, and so he weeds such prospective patients out of his practice that way.

An audience member suitably questioned this habit, asking how could a specialist be expected to determine if a medication caused headache or nausea? I think it’s kind of a sneaky way to get rid of patients who want buprenorphine monoproduct.

I have the same fears when fielding new calls from prospective patients. I’ve instructed my patient contact representative (who is also my office’s licensed professional counselor, after-hours contact person, pharmacy liaison, licensed clinical addiction specialist, prior approval wrangler, and fiancé) to tell these people that I do not prescribe the monoproduct to new patients. I have no problems saying “no” upfront to these patients, and try to explain why I’ve made this decision for my private practice (even though, as above, I have prescribed it for patients I know very well).

I use the monoproduct in the opioid treatment program where I work, because those patients dose with us every day until they have a period of stability. The dosing nurses roughly chop the tablets, to minimize diversion, and patients stay on-premises until the medication has dissolved, also to make diversion more difficult. These patients don’t get any take home doses until we feel they have stabilized.

We also discussed how long to keep patients on buprenorphine. The bottom line is that no one knows. Best outcomes are seen in patients who stay on buprenorphine, since there’s still a high relapse rate back to opioids in patients who stop buprenorphine. I ask my patients periodically if they wish to start a slow taper, if they’ve been stable for over a year. I don’t push them to taper if they’re not ready, but if they are, I recommend they taper slowly. From the discussion at this meeting, it sounds like most of my colleagues do the same.

We discussed the maximum daily dose of buprenorphine. According to studies, a daily dose of 16mg saturates most of a patient’s opioid receptors, and increasing the dose to 24mg only gives about a 4% increase in the number of covered opioid receptors. Some doctors say this shows buprenorphine should never be dosed more than 16mg per day.

However, about a third of the doctors in the room raised their hands when the moderator asked if they had any patients who seemed to require 24mg per day to stabilize.

I didn’t interject anything into the discussion, but I just went to a session at the national ASAM meeting where this same topic was discussed. While it’s true that basic pharmacology would indicate 16mg is probably the just as effective as 24mg in most patients, several studies have shown better patient retention in treatment when higher doses (24-32mg per day) are used.

It’s possible this isn’t a physiologic effect, but more of a mental process. We can’t be sure. But for whatever reason, if my patient does best at 24mg, I’ll allow her to stay on that dose.

For patients on higher doses, we need to make sure they aren’t diverting some of their medication. Patients sometimes ask for a higher dose than they need, in order to get enough medication to treat a friend, family member, or significant other. Some doctors call this “piggy-backing.” Even though it means a suffering addict is getting treatment, the piggy-backer won’t get any counseling. Also, law enforcement types use examples of diversion to demonstrate that buprenorphine is a bad street drug, contributing to the stigma against patients doing well in their treatment. Diversion threatens the whole concept of office-based treatment program.

All in all, we had two hours of lively interaction on the finer points of office-based prescribing of buprenorphine. I don’t think all doctors will agree about everything, but it’s nice to hear what other physicians are doing, to make sure I am not too far out of line with the standard of care.
