Advances in addiction treatment medications

Thursday, June 24th, 2010

As our understanding of the reward-reinforcement systems and other brain functions increases, more medications are being developed for the treatment of addictions – naltrexone and buprenorphine for opiods,  bupropion  for tobacco and others.  And they hold promise for help with more than just drug addiction. Dr Inaba comments.

Holidays – Guilt, Gambling & Java

Friday, December 11th, 2009

People with substance abuse issues often find that the Holiday Season can bring up old wounds – we look at some of the issues around guilt for the addicted person. Also news about treatment for gambling addiction, and a chat about the addictive qualities of caffeine.

Listen to podcast

Transcript (edited):

Welcome to the CNS podcast featuring Dr Darryl Inaba research director for CNS Productions.

CNS: Hi and welcome once again to the addiction podcast from CNS Productions, I’m Howard LaMere here with Dr. Darryl Inaba. Darryl, in continuing with the holiday motif, we’re talking about guilt as one of the reasons for an increase in addiction during the holidays.

Darryl: I think it’s absolutely accurate. Lynn O’Connor of Wright Institute did a study of women who seem to have more guilt and shame than men. The study looked at addicts and alcoholics entering treatment and measured guilt, shame and alpha-beta pride and found that those coming into treatment suffer tremendous amount of guilt, tremendous amount of shame about they’ve done. They have a low self esteem, low pride in themselves and are on the receiving end of a lot of anger from their families who have seen them make promise after promise only to break them all.  Recently I’ve been working with gamblers and I am finding this anger more prevalent in gambler families. During the holidays there is a lot of societal pressure to interact with friends and family – those we might have injured and hurt, so there is going to be a lot more guilt, shame, and feelings of low self esteem, which contribute to the desire to alter your state of conscientiousness. The easiest way for people with compulsive disorders to alter their states of consciousness is to partake in those activities that screen or suppress their feelings of guilt and shame for a while. This desire to feel better leads to more slips and therefore more relapses during the holiday season.

CNS: More so than the rest of the year, just because of the pressure. We’ve talked about drug relapses, we’ve talked about food. Now there’s another topic in the news – caffeine addiction. A report from the surgeon general stated that caffeine was habituating, rather than addicting. I don’t think anyone who drinks coffee would dispute the fact that it’s addicting. I mean I have to have that first cup of coffee in the morning, I try, I try having tea, green tea, which has caffeine anyway and it’s still not the same. I mean, there’s something very addictive about caffeine and so how can anyone say it’s not addictive?

Darryl: Well, it goes beyond denial, there’s certainly going to be denial in terms of any kind of addiction. When it comes to caffeine it’s almost a cultural reticence or a fear that this – the last thing left to alter our states of conciseness – is going to be taken away, or looked on negatively, and so caffeine…

CNS: More guilt…

Darryl: A lot more guilt.  Caffeine has remained under the radar for lots of reasons. It’s escaped any crucial examination. We’ve looking at nicotine and other substances like alcohol, but caffeine is probably the last thing we’ll look at with that much scrutiny. Caffeine is defiantly an addictive substance. It’s a xanthine alkaloid, it’s a stimulant, it creates similar, although at much lower levels and intensity, changes in the body as does cocaine, and nicotine and methamphetamine. It affects the same processes in the brain. Scientists have looked at caffeine for a long time and believe that anytime you drink over five hundred milligrams a day of caffeine, your brain and your brain chemistry is altered. Researches see the beginnings of compulsive or addictive tendencies.  Above eight hundred to one thousand two hundred milligrams of caffeine a day a person begins to have negative body toxic effects. I’ve always felt that caffeine maybe responsible for a lot more deaths than cocaine and heroin just from the toxic effects it can render to your heart and blood vessels. Caffeine causes distress in those areas of your physiology. As you mentioned, everybody who consumes caffeine, knows about withdrawal when they try to stop. The headache, that pressure headache in the front of your brain can last several months to a year before it finally begins to dwindle and go away. So caffeine is physically addicting, it’s certainly emotionally addicting.  I don’t know anybody who realizes that they use caffeine to get stimulated in the morning to wake up, to do their work and to get off on their day. When they take a vacation, take several weeks where they don’t have to get up and do anything – just eat and have fun, they still reach for that cup of coffee automatically, instinctively without even thinking. This is a true, true dependency and a true habituation. So caffeine is defiantly an addictive substance, defiantly something that that we’re going to have to look at in terms of how it’s affecting our health.

CNS: Like the hybridization of marijuana, the proliferation over the last 5 or 10 years of coffee shops that sell really strong coffee, from  Seattle to Silicon Valley,  we must wonder if it’s related to computers and dotcom and the generation x factor, I don’t know that that’s true but we’re definitely seeing stronger caffeine products.

Darryl: I actually had to detoxify and go into recovery for caffeine addiction some twenty-five, thirty years ago.  I found myself unable to go through the day without a cup of coffee in my hand. I had tremendous headaches each morning and they went away with that first cup of coffee. It was better than aspirin or anything else. When I realized my blood pressure was up and my heart had some unusual beats I recognized it was caused by my caffeine dependency and I stopped. Since then, I’ve been in rigid caffeine recovery – no coffee. Unfortunately, no one can totally avoid caffeine. It’s in cold products, aspirin, sodas, chocolates, candy- it’s everywhere. I deal with it in an unusual way. I make coffee for my wife. Ever since I stopped drinking coffee twenty five years ago, I get up the morning before her and make her coffee. Her tolerance increased over the years and now I have an espresso machine. She graduated from Starbucks and is into much stronger Pete’s coffee from San Francisco. There’s no end to where it’s going but you can definitely see that pattern. I’m just lucky that I don’t have a strong desire when I smell it; I have a strong desire in the morning…

CNS: …are you getting something from your nose?

Darryl: Yes, but I have to remind myself that I can’t – otherwise I won’t stop.  I’ll have that cup in my hand all day long and end up like I did before.

CNS: Another topic in the news this week is treatment for gambling. Perhaps gambling is not as much of an issue during the holidays as some of these other things we’ve talked about but for people that have an addiction of any sort it doesn’t stop for a holiday. So what’s in the news on gambling?

Darryl: Well, it’s very exciting news. I’ve always believed that it’s not the particular activity or the drug that causes a compulsivity to continue something even though it’s creating a tremendous negative impact on your life. It’s actually the ways the brain differs in certain individuals that conspires to rob them of their control and then conspires to keep them engaged in that activity even though they desperately what to stop. I don’t know if there’s a stronger addiction than gambling. I’ve worked with cocaine addicts and alcoholics and heroin addicts but working with gambling addiction I’ve concluded that it is one of the strongest addictions. Perhaps it is because our society doesn’t place a stigma on gambling. Society labels addicts “problem gamblers” and/or “pathological gamblers”. Pathological gamblers can’t stay away from the action and they bet everything. They loose their home, they loose their vehicle. More people are walking the streets to work and walking around town not because they are alcoholics who lost their license, but because they gambled away their vehicle and any money buy another one. They max out credit, get themselves in terrible debt, and start participating in illegal activities.

With the advent of brain imagining in the  1980’s, researchers found the same type of changes and the same activity in the gamblers brain as they made a bet as they saw in the cocaine addict’s brain or a meth addict’s brain taking a hit. The brain process and the pathways are the same. What I find exciting is that now medicine has recognized that similarity. Medication that was originally developed for heroin addiction and then was found to be effective in blocking craving in alcoholism is also actively helping gamblers. By giving them naltrexone, an opiate antagonist that blocks the opiate receptors from opiates, which blocks a gamblers craving. They are able to remain in recovery and are better able to avoid taking that first bet.  This has created a better understanding of what addiction is and opened an avenue for more appropriate and better treatments to help people with this condition.

CNS: It’s exciting that we are finding ways to address these issues but I’m again reminded of 1984, there’s a danger of taking drugs to deal with drugs.

Darryl: Maybe so but in another reality, as I work with addicts, I think it’s a wonderful thing that’s happening. The important thing to focus on is that addicts, especially gamblers beat themselves up wondering why they’re doing what they are doing. Now they are finally beginning to accept, through this whole medical process, that they really have an illness, that they’re not weak willed individuals, they’re not bad, stupid, crazy, or amoral. They have a biological difference that makes them unable to control these behaviors. This helps them to accept that they need treatment and they need to practice recovery better and with vigor.

CNS: Other options are the organic things that we can do. We’ve talked about singing and dancing and other organic things that make us feel good.

To those folks listening, your comments and questions are more than welcome. Stop by the web site www. cnsproductions.com, drop us an email and we’ll address your questions. Darryl, happy holidays once again.

Darryl: Stay warm, Howard, its getting cold.

CNS: Yes it is definitely winter, ok, bye-bye, that wraps our pod for today. Thanks for visiting the CNS pod cast. Please check back soon for the next in the series and visit our website www.cnsproductions.com.

Low Dose Naltrexone for Immunological-Related Disorders

Tuesday, February 24th, 2009

October 2008, was truly an historic month! We witnessed the final days of the most historic presidential campaign in US history and the enactment of the Emergency Economic Stabilization Act of 2008 that would eventually pump $700 billion into an economy that has turned into a recession and perhaps headed toward depression. Imbedded in that historic Act was to me the most notable piece of the legislation -   the Mental Health Parity and Addiction Equity Act of 2008 ending rampant discrimination against Americans suffering from substance use disorders. Another October event was the Fourth Annual LDN Conference at the University of Southern California Health Sciences Campus in Los Angeles, California.1

LDN is the acronym for Low Dose Naltrexone. This was the fourth time the conference focused on this therapy signaling a rising level of confidence in the low dosage use of this opioid antagonist to treat a growing number of immunological-related disorders. Although the use of natrexone in the treatment of such conditions is not directed related to addiction or its treatment, I find its development to be so fascinating that I feel compelled to comment on it.

Naltrexone (Revia®, Depade®, Trexan®,Vivitrol®) is a powerful opioid receptor antagonist that is very useful in the treatment of opiate and alcohol dependence. It was the first US Food and Drug Administration (FDA) medication approved to treat a drug craving, specifically alcohol craving. This gave scientific validation to the idea that drug craving is an actual biologic manifestation and not merely manipulation by addicts to excuse a relapse.  Naltrexone was first approved to treat opioid addiction in 1984 as a medication that would block the effects of opioids if a recovering addict were to experience a “slip” after detoxification. The medication blocks opioid receptors in the brain preventing the addict from experiencing any effects and thereby preventing relapse. In reality, naltrexone is actually an endorphin/enkephalin receptor antagonist because our natural brain and body receptors are there for naturally-generated, endogenous, opiate-like brain chemicals: our endorphin/enkephalin neurotransmitters, rather than for external opioid drugs. Heroin, Vicodin®, Demerol®, Oxycontin® and other external opioid chemicals that by coincidence happen to mimic the chemical “signature” for our body’s own endorphin/enkephalin receptors. The FDA granted naltrexone approval for the treatment of alcohol dependence in 1995 after the medication was shown to reduce alcohol cravings in recovering alcoholics. Many clinicians and treatment programs continue to employ natrexone to treat a variety of “off-label” conditions (medical uses for non-FDA approved treatment indications) such as methamphetamine, nicotine, and other drug cravings. It has even been used to curb a “cutter’s urge to mutilate their skin. For these uses, naltrexone is usually prescribed at the same dose of 50 mg. to 150 mg. originally approved for blocking effects of opioid drugs or alcohol cravings and lasting 24 to 72 hours.  The rationale for using naltrexone to treat compulsive behaviors and drug dependencies other than opioids or alcohol is the hypothesis that cravings for these activities emanate from the same brain areas and involve the same neurotransmitters regardless of the specific drug being abused or the compulsive behavior practiced. The theory is if naltrexone can control alcohol and heroin craving, it could also control cravings for other drugs of abuse and compulsive behaviors like cutting and gambling.

In 1983, Dr. Ian Zagon discovered that naltrexone prolonged the survival of mice suffering from neuroblastoma cancer.2 During the mid 1980s, Dr. Bernard Bihari of Beth Israel Medical Center in New York began human research on the use of naltrexone at low doses of 1.5, 3 or 4.5 mg./day to treat AIDS and ARC. His work was presented at several International Conferences on AIDS in the late 1980s.3,4 He also began using LDN to treat a variety of immune system related illnesses and opened the door for additional research. Today, investigators are looking at LDN to effectively treat a vast number of difficult and often treatment resistant oncological and immunological disorders. By the October 2008, Dr. Bernard Bihari and a number of medical practitioners reported beneficial effects from Low Dose Naltrexone in the treatment of:
Alzheimer’s Disease
Amyotrophic lateral sclerosis (ALS)
Ankylosing Spondylitis
Autism Spectrum Disorders
Autoimmune Polyendocrinopathy- candidiasis-ectodermal dystrophy (APECED)
Behcet’s Disease (a type of vasculitis)
Bipolar Disorder (Mood Disorder)
Cancers –
Bladder Cancer
Breast Cancer
Carcinoid
Colon & Rectal Cancer
Gliobastoma
Liver Cancer
Lung Cancer (non-small cell)
Lymphocytic Leukemia (chronic)
Lymphoma (Hodgkin’s & Non-Hodgkin’s)
Malignant Melanoma
Neuroblastoma
Ovarian Cancer
Pancreatic Cancer
Prostrate Cancer (untreated)
Renal Cell Carcinoma
Throat Cancer
Uterine Cancer
Celiac Disease (gluten intolerance)
Chronic Fatigue Syndrome
CREST Syndrome (limited scleroderma)
Crohn’s Disease (granulomatous colitis & regional enteritis)
Chronic Obstructive Pulmonary Disease     (COPD or emphysema)
Depression
Endometriosis
Endometriosis
Fibromyalgia
HIV/AIDS
Infertility
Irritable Bowel Syndrome (IBS)
Multiple Sclerosis (MS)
Murine Inflammatory Bowel Disease
Myalgic Encephalomyelitis (ME)
Obsessive Compulsive Disorder (OCD)
Parkinson’s Disease
Pemphigoid (blistering skin disease)
Premenstrual Syndrome (PMS)
Polycystic Ovarian Disease (PCOD) or Syndrome (PCOS)
Polymyalgia Rheumatica (PMR)
Primary Lateral Sclerosis (PLS)
Psoriasis
Rheumatioid Arthritis (RA)
Sacoidosis
Scleroderma
Stiff Person Syndrome (SPS)
Systemic Lupus Erythematosis (SLE)
Transverse Myelitis
Ulcerative Colitis
Wegener’s Granulomatosis (a type of vasculitis)

Reports on the efficacy of LDN to decrease severity of symptoms, stop the progression of or even reverse the development of the conditions listed above have been anecdotal  rather than “empirical” (rigorous scientific) to determine their validity.

Although there is a lack of empirical studies to confirm LDN’s beneficial effects, the large number of anecdotal reports and the fact that the low dosages used exposes patients to only minimal, if any of naltrexone’s side effects, is enough for some scientists to recommend its use as a general health tonic as well as for specific medical conditions. Norman Brown and Jaak Panksepp, neuroscientist at Embry-Riddle Aeronautical University in Daytona Beach Florida speculate that LDN can be used as a buffer for a large variety of physical and mental ailments due to its ability to beneficially modulate both the immune system and regulate positive neurotransmitter affects. Brown and Panksepp agree that LDN supports immune-modulation that can reduce cancerous and inflammatory autoimmune processes. They also cite the ability of LDN to up-regulate endorphin/enkephalin activity to promote stress-resilience, exercise, social-bonding, and emotional well-being when reducing problems of autism and depression.16

The proposed mechanism of action for LDN’s positive effects on treating such a wide spectrum of disorders is due to its ability to up-regulate endorphin levels in the body. Dr. Bernard Bihari discovered that the human body produces almost all of its daily quantity of beta-endorphins between 2 am and 4 am. Partially blocking endorphin receptors for that 2 hour duration by administering a very low dose (1.4 to 4.5 mg) of naltrexone at bedtime supposedly stimulates the brain’s production of more endorphins than usual in an attempt to overcome the partial blockage of its endorphin/enkephalin receptor sites. Dr. Bihari found that doses below 1.5 mg. had no effects on blood levels of beta-endorphins during the following daytime hours and doses larger than 5 mg. caused too great of an endorphin blockage. His research revealed that LDN at bedtime resulted in a doubling to tripling of beta-endorphins circulation in the blood the next day.6 Animal research by Dr. Ian Zagon showed that LDN resulted in a marked increase in circulating met-enkephalin levels as well.5 Endorphins have been found to play a central role in the beneficial orchestration of our immune system. Endorphins/enkephalins alter the development, differentiation, and function of immune cells which have opioid-related receptors on their cell membranes. Bone marrow progenitor cells, macrophages, natural killer cells, immature thymocytes, T-Cells and B-Cell are all affected by endorphin management.5 Increasing levels of the body’s natural opioid neurotransmitters (endorphins/enkephalins) via LDN therapy, is projected to result in more positive management of the human immune system. Those who suffer from immunological-related disorders have low levels of endorphins.5,6

Despite the enthusiasm generated by the last four national LDN conferences and of those who are finding it effective in the treatment of many difficult to treat immunologic disorders, the prospect that LDN will soon be fully approved by the FDA is not certain. The FDA will require rigorous testing of LDN for each specific medical condition it is being used to treat. The testing process for each condition is costly despite the 1983 US Orphan Drug Act. Since naltrexone’s original drug patent has expired, it is more profitable for pharmaceutical firms to develop new medications than to invest in developing new uses for a patent expired medication. Further, most of the immunologic-related disorders that it could potentially benefit are rare. Drugs developed to treat very rare conditions (affecting less than 200,000 individuals) often become “orphan drugs” because there is little financial incentive for pharmaceutical companies to invest millions of dollars on the research needed to gain full FDA approval. This economic reality is the reason very promising medications are often abandoned or orphaned by drug companies.   Orphaned Drugs can still be used to treat “off-label” medical conditions and groundswell movements like the National LDN Conferences help to establish and promote such therapies.

A final comment, I was doing some research on the history of cocaine in the 1960s and remember coming across Uber Coca, a treatise authored by Dr. Sigmund Freud in 1884. Dr. Freud’s enthusiasm for positive medical uses of cocaine prompted him to recommend it for the treatment of over 360 medical conditions. It is now clear that Freud’s early enthusiasm stemmed more from the euphoric effects that cocaine generated for the prescribing physicians than from actual health improvements shown by their cocaine treated patients. Similarly, current investigators should curb their enthusiasm as they see LDN therapy deliver positive outcomes with so many difficult to treat diseases. Empirical research is needed to confirm their positive anecdotal observations. If the US Pharmaceutical Industry is not willing to invest in this promising medical treatment, perhaps it is time for public or government entities to step in and take it to the next step.
