Can a Pill Cure Your Addiction?

Can a Pill Cure Your Addiction?

By the time he turned 50, Olivier Ameisen was a successful cardiologist living in New York City. Still, the French-American physician couldn’t shake the feeling he was “an imposter waiting to be unmasked.”1
Ameisen was an alcoholic, a fact that “numerous emergency hospitalizations, emergency room visits, detoxifications, [and] years of inpatient and outpatient rehabilitation treatments” had failed to change.2 “I detested the taste of alcohol, but I needed its effects to exist in society,” he writes in his book The End of My Addiction. All told, he estimates that at this point in his life a typical night of drinking consisted of 750 ml of Scotch,3 the equivalent of 17 drinks.
This is where Ameisen’s life stood on January 9, 2004, when, inspired by a report inThe New York Times,4 Ameisen decided to take a new approach. For years, doctors had used the drug baclofen to treat muscle spasms in people with multiple sclerosis or spinal injuries. But according to one patient prescribed the medication, the effects went one step further, acting like a wet blanket tossed over the fires of his cocaine-addicted brain’s cravings.
Cured by a Pill?
This wasn’t the first instance in which the drug had demonstrated the potential to reduce and even eliminate what Dr. Anna Rose Childress, the researcher behind the New York Times report, refers to as “throbbing, pulsing desire states” brought on by drugs and alcohol.5 Previous studies in rats 6 and, to a limited extent, humans 7 had indicated the drug’s potential beyond treating muscle spasticity. Nevertheless, Ameisen’s doctors “remained unconvinced” when he approached them with the idea. And so a desperate Ameisen did the only thing left to do and self-prescribed the drug, slowly increasing and then decreasing his dose until finally striking on an amount that shielded him from the desire to drink while minimizing the most significant side effect of drowsiness.8
In December 2004, the Journal of Alcohol and Alcoholism published Ameisen’s report on his one-man study. This was followed four years later by the cardiologist’s best-selling memoir.9
The response was immediate. Hundreds flocked to message boards where they passed notes back and forth on dosage size and frequency. Meanwhile, doctors around the country began prescribing it to patients. 10 As they did, the research kept coming in.
Inspired by Ameisen’s story, addiction psychiatrist Dr. William Bucknam prescribed a high dose of baclofen to an alcoholic patient, who quickly found drinking became “an alien world” to him. What’s more, the man found that when he did drink, he was able to do so in moderation.11
In 2011, the Journal of Alcohol and Alcohlism, the same journal that published both Ameisen’s and Bucknam’s studies, published yet another on baclofen. The results: A daily dose of 30 mg for 12 weeks resulted in a 53 percent reduction in the number of drinks a person had each day. Bump that up to 60 mg, and this number jumped to 68 percent.12
How It Works
To understand how baclofen and similar drugs work, it’s important to understand a little bit about cellular receptors, and specifically those located on the surface of the cell. The idea is simple, really. The receptors act like messengers ferrying news, which arrives in the form of a molecule, into the cell from the outside world. Block the receptor and you block that molecular message from ever reaching the cell.
As GABA-B receptor agonists, baclofen and its relatives do exactly that. They act like guards standing watch against those molecules responsible for binding with cells in order to produce a drug-induced high or alcohol’s warm glow. For years, journalist Gabrielle Glaser has reported on alcoholism for places like theNew York Times and The Atlantic. Eventually, she decided to give baclofen a try herself. “It made a second glass of wine seem about as enjoyable as a glass of Dimetapp.” 13
When this happens, that is to say as soon as a substance is robbed of its feel-good qualities, avoiding it no longer demands the same energy and attention as before. In the case of Ameisen, this new-found freedom meant he “would no longer plan life around alcohol. Alcohol thoughts no longer occur. I undertook personal and professional projects, which I was unable to do so before as I had to anticipate consequences of unpredictable drinking episodes (cancelling appointments when possible and blackouts). As taught in [Cognitive Behavioral Therapy], I avoided places, situations, social settings and vacations where alcohol might have been present. I no longer notice liquor sections in supermarkets.” 14
Roadblocks
In 2013, the cardiologist died of a heart attack at the age of 60. But the research he helped pioneer continues.
Just last year a study found that 68 percent of patients randomly assigned baclofen remained abstinent during a 12-week high-dose period when compared to just 24 percent of those given a placebo.
Reflecting on the results of the 56-person study, Dr. Philippe Jaury told Medscape Medical News: “When you go to Alcoholics Anonymous, people say to themselves, ‘Today, I won’t drink.’ So alcohol is still in their mind, they just have to tell themselves that they are not going to drink today. But with baclofen, abstinence is passive; when it works, thoughts of alcohol are not in your mind anymore. You can drink if you want to, but you can stop, and that’s what has impressed me about this drug ― after patients start drug therapy, they tell me, ‘I don’t need to drink anymore, I don’t like it,’ and that was not their objective before they started treatment.” 15
And yet despite all this, few addicts will ever even hear the word baclofen. Glaser, the journalist who decided to give baclofen a go herself, estimates that a mere one percent of those suffering from alcohol use disorder “are ever given the choice… to take any sort of medication.” 16 John Bowersox, spokesman for the National Institute of Alcohol Abuse and Alcoholism, puts it at two percent. 17 Though much higher among those treated primarily for either heroin (27 percent) or opioids (18 percent), the number remains very much in the minority. 18
Dr. Petros Levounis is the chair of the Department of Psychiatry at Rutgers New Jersey Medical School and a member of the American Psychiatric Association Council on Addiction Psychiatry. According to him, there is good reason for this, at least in the case of baclofen and alcohol addiction.
“What has been lacking is substantial clinical research to show whether high-dose baclofen is truly helpful in the treatment of alcohol use disorder,” he said, arguing that studies to date have been too limited in their scope to justify such a fundamental shift as officially toting the drug as a cure for addiction. 19
“It is at best premature and at worst irresponsible and dangerous to tell patients who suffer from alcoholism that now you can drink if you want to but you can stop, because of presumed protection from baclofen,” he warned. 20
Of course, there are a number of drugs designed to fight addiction that are vetted. In 1972, the FDA approved methadone for opiate addiction. Touted as a safer alternative, Suboxone was introduced in 2002 for the same purpose. Then in 2006, the FDA approved naltrexone for alcohol dependence and then four years later for opioid dependence.
Still, medication-assisted treatment has yet to form the basis of mainstream treatment of substance abuse disorder. And it won’t, according to Marjean Searcy, until the way we look at the condition changes.
“So long people have seen it as a moral issue. Or a criminal issue. We need to shift it into a medical model,” Searcy, the project director for the Central Rockies Addiction Technology Transfer Center, told Foundations Recovery Network.
The 12-Step Program Monopoly
The battle is an uphill one. As Glaser has demonstrated in her reporting, world of addiction is one that has long been monopolized by the 12-Step program approach.21
It’s difficult to track the effectiveness of either Alcoholics Anonymous or its sister-program Narcotics Anonymous. Part of this, she notes, is the inescapable result of the anonymous nature of AA/NA. 22 Without any sort of information collected on who attends these meetings, it’s difficult to, for instance, compare trends over time, be it in the case of an individual or an entire country.
By comparing outside studies going back to as early as 1966, however, one group of researchers was able to circumvent this problem in part and evaluate the effect of AA and the 12-Step approach in the lives of a little more than 3,400 people. Based on this, the researchers concluded that “no experimental studies unequivocally demonstrated the effectiveness of AA or [12-Step facilitation] approaches for reducing alcohol dependence or problems.” 23
Neither is Glaser alone in the push away from the AA model toward one she sees as committed to viewing addiction as a disease—not a moral failing. Dr. Mark Willenbring is the former director of the National Institute for Alcohol Abuse and Alcoholism, where he says he saw tax-supported research in favor of new drug and behavioral therapies for treating drinking problems pour in. 24
“But nobody was paying attention.” Willenbring, who now operates a private rehabilitation clinic in Minnesota, attributes this in large part on the fact that, unlike other fields of medicine, in the world of addiction, when treatment fails, the patient is blamed. 25
But even in those cases where physicians and rehab specialists are aware of these drugs, trepidation abounds. For one, removing the ability to feel high or drunk does not necessarily remove a person’s reasons for drinking, be it anxiety, depression, chronic pain, social anxiety or something else entirely. This was the case for Billy Webb, who at one point attended 110 AA meetings in 70 days in his search for sobriety. Webb had first started drinking in his teens to help his social anxiety. By the time he was in his mid-20s, he was downing 20 to 25 drinks a day. For years he was in and out of treatment before he was introduced Willenbring’s clinic, where he was prescribed naltrexone. Almost immediately, he was able to limit his drinking to two to six drinks a day. The difference, he says, lay not in the taste but in the effect. “I didn’t get that same rush in my head.” 26
And for a few months, it looked like Webb had found the solution to his drinking problem. But it didn’t stay that way. Ultimately he missed feeling intoxicated so much that he stopped taking the drug. “I missed feeling like myself.” These days, he is on a new drug—gabapentin—and still meeting with a therapist. Included in the mix again: AA. 27
Best of Both Worlds
True, baclofen and others like it may not represent a kind of cure-all, at least not for everyone. But there is one thing that is certain, and that is something needs to change—and fast. From heroin to pain relievers, death by overdose is on the rise, in some cases multiplying by six-fold within a 13-year span, as in the case of the heroin. 28 Meanwhile, excessive alcohol use claims an estimated 88,000 lives each year, amounting to 2.5 million years of potential life lost between 2006 and 2010 alone. 29
If we are to effectively combat this trend, Searcy says an approach like the one Webb most recently settled on—attending AA and taking baclofen—is critical. This, she says, is the one-two combo that, more than 12-Step programs or medication alone, often knocks addiction off its feet.
In this way, Searcy says addiction is very similar to our approach to mental health. Not very long ago, depression and other mental illnesses were deemed a personal failing, something to snap out of. “As medications got better and we realized you could do things with medication to change a person’s brain,” that changed.
Searcy believes this shift is happening again, only this time with addiction. As evidence, she points to a recent acceleration in research regarding medication-assisted treatment for addiction, a trend she calls “really exciting.” According to Searcy, “We’re changing the way we look at substance use disorder. We know it’s a disease.”
