Yeah. Yeah, mm Alcoholism in the 70's with Charles E. Becker MD. Chief of clinical pharmacology. San Francisco, General Hospital san Francisco California. I call your attention to the reference which I've listed for you in the third part of the basic discussion. This was an article that appeared in the annals of internal medicine called self destructive habits. And they're probably many people in your practice who have difficulty and would wish their tombstone to look like this. Namely they told you that they were sick and that you didn't help them very much during their lifetime. These are your smokers, your drinkers, you're obese patients and dr Barnum had the courage to look over his private practice and to see what percentage of his patients were in fact inflicting illness upon themselves. And some of this is summarised on this slide. He reviewed the fact that the medical literature says that we have 9-10 million alcoholics. Although it's not exactly clear where this comes from that we consume huge quantities of cigarettes. That large numbers of people are using marijuana who prescribed million of barbiturate tablets are many people using amphetamines. We have heroin addicts and something in the order of a third of the population is seriously overweight. Two standard errors. And he concluded that in his practice, one quarter of all of his patients, whether hospitalized or outpatient, were trying to kill themselves, and that he didn't know exactly what to do about it. This was remarkable because the abuse that came to poor Dr Barnum for writing this in the editorials was somewhat unfair. As you know, many people have defined alcoholics or somebody that people who drink more than their physicians. And of course, this has not been an adequate way of diagnosing alcoholism and that people argued that he did in his treatment of alcoholism, for instance, that Dr Barnum did less than the spontaneous remission rate that's been reported for this disease. He did quite well with obesity and moderately well with smokers. And people suggested that he didn't understand that these really aren't habits, but that these are diseases and in fact, the emphasis of whether alcoholism and narcotic addiction of diseases or habits was played out very beautifully in the annals of internal medicine. Well, you can see what the difficulty is is because many people have tried to care for alcoholics or smokers or beast patients who don't have the problems themselves uh in for well, why don't you just simply stop eating or just cut down your alcohol intake or stop smoking? Um, anybody who's ever had the problems of any one of these addictions knows that it's much more complicated than that, and especially if you're a position who doesn't drink or smoke or is an obese, you have a very hard time identifying with these kinds of patients Well, part of the reason is because we've had difficulty with defining exactly what addiction is and what the risks are for the consumption of cigarettes, alcohol and narcotic drugs. And that's part of what I'd like to do for you. And you'll see that in the final handout in the back part I've summarized in in overall sense what drugs do to patients and when we refer to someone being addicted to a drug, it usually means three things. It means a statement about behavior which is sometimes referred to as habituation and there are physical factors called withdrawal and tolerance. These are the factors that are best understood, the ones that we know the most about and the things that I'll be discussing today, these are the ones that often call the patient to our attention. But it's the behavioral factors that were least familiar with. We don't fully understand them. We don't exactly see how they're applicable on this slide. I summarize for you when it comes to talking about addictions and drug dependencies that there are many people in our society who use drugs and some who abuse them to a state of physical dependency where we see withdrawal and tolerance, but the drug only makes up part of that, the personality makes up part of it and the social environment makes up part of it. So as an example, using the drug, alcohol is our marker drug for this discussion. The average American citizen based on tax dollars consumes the equivalent of 3.93 gallons of 100 proof booze per person per year. This works out to be three cocktails for every person of drinking age every day. Now you're saying to yourself, well, how come not everyone drinks this quantity, that's because 80 of that total quantity that's used in our society is consumed by only 10 of the people. And it's that 10 of the people who are the alcoholics. And it's equally clear that most of us who use alcohol in a way, which doesn't seem to get us into difficulty, don't fully appreciate the magnitude of this problem. Nowhere is this problem more obvious than in industry and in the military service. So you will note that that not only is their use of problem, but for some reason, only a small percentage of people who abused drugs arrive in a medical diagnosis of the abuse of the problem. Now, part of it has to do with the drug itself and I've noted on the your handout, but I've seen people have used virtually every drug known to man, except one in 1000. There has never been an addict of matthias scenes. In fact, you have to be crazy to take those medicines. Yeah, as uh as an internist who sees this problem all the time. One of the best ways to diagnose crazy craziness in your private practice is to give someone Matthias means anyone who says that they're feeling better. Taking those medicines are crazy. It has something, it has something to do with the drug. Uh, we know that nicotine and narcotics, if given to laboratory animals are the most preferred drugs. Alcohol, marijuana LSD are less preferred. It has something to do with the dose and a lot to do with the toxicity based on dose. That's something to do with the root. As an example, cocaine is very much different in its addiction, whether it's snorted or uh injected, it has to do with the psychological setting in which the drug is administered. It has to do with the previous psychological state. And we'll have a lot to say this afternoon. It may have to do with the set of receptors that you have in your brain now part of this and some of the new information. Since this is an update has to do with the genetic predisposition to not only the medical complications but to the abuse of the drug and in the alcohol area. This is some of the hottest information that we have, namely that if you look to see whether it could be a psychological factor that's involved as something that was inherited. We have called people who abuse alcohol all of these things neurotic, over reactive protective and every one of these things. And no matter how you slice it as an internist, looking at all the studies when people who are addicts are looked at, they turn out to be essentially normal. This has not born a lot of fruits in terms of the basic personality part, in terms of giving us an idea about the predisposition of people, we can give some patterns to be sure, and there are some common traits, but the usual overall pattern has not been remarkable for any of us taking care of this kind of patient. What has been remarkable is the potential for an inherited part to this whole area and in the field of alcoholism. And I've listed for you some of the references, but I'd like to tell you that this brand new book that was just published by Donald Goodwin called Heredity and alcoholism, which summarizes all of this. And there are six lines of evidence that suggests that there is genetic predisposition to alcoholism. There's a family history, there are striking racial and religious preferences as an example of their oriental people in san Francisco who don't drink at all because every time they drink they flush and feel terrible. There's a whole area of research that suggests that maybe alcoholism is not only just consumption and toxicity, but predisposition based on the pharmacological effects. We have some dramatic twin studies which suggest that if identical twins are raised in a different environment um at birth and separated at birth, that they have a higher incidence of alcoholism and identical twins and non identical twins. There have been associations for color blindness, and there have been uh animal studies that have shown that you can actually inbred animals to prefer alcohol and make them again and make them again and create species of animals that are that are alcoholic. In addition to that, if you give genetic blocking material, you can block this preference. This is an important, uh by the way way of us discovering new drugs, because in fact, lithium, as I will mention in a minute, has been placed in the drinking water of the inherent bread preferenced animals for alcoholism and they dramatically decrease their alcohol intake. Then when the lithium is removed, they start drinking again. And this has led us to do clinical trials, which I'll discuss in a minute, suggesting the potential value of lithium in the treatment of alcoholism. Well, all of this I think people have appreciated before. But the hottest area in the field of alcoholism today is called the fetal alcohol syndrome and raises another question about how genetics might relate to the consumption of alcohol. This was totally unrecognized because in the 1950s people began to look at what drugs were affecting the fetus and a complete surprise to everyone was as depicted on this slide, the performance, growth and development I. And other changes that occurred in mothers who did not drink during pregnancy. By comparison to those mothers who consume large amounts of the drug alcohol during pregnancy and the drug that was most commonly associated with performance, growth and development. I and other changes was the chronic consumption of the drug alcohol. This is extremely important because now it's recognized that the fetus may be intimately affected by the alcohol that's consumed by the mother and that there may be alterations in receptors, which I will discuss this afternoon, particularly opiate receptor. Or there may be structural or enzymatic changes which occur in the fetus when when the mother is exposed. This is now called the fetal alcohol syndrome and was initially felt to be a structural abnormality. We now appreciate the fact that infants born of mothers who are drinking heavily. And I might add, recent evidence suggests who are smoking heavily and often they go together. Uh, in fact, in the 12,000 alcoholics that I've taken care of, there's only been five non smokers drinking and smoking go together. And in fact, in these studies, it's been hard to separate the risk of alcohol during pregnancy and smoking during pregnancy. The result of all of this was to suggest that infants may be born in a withdrawal state or in a tolerant state to alcohol, and the early life experiences which the infant undergoes may be occurring in the presence of drug withdrawal and may be associated with later life experiences that we call addictive behavior, if you will. Now, all of this is very preliminary, but you can expect to see a whole host of articles coming out about investigating the effect of common things such as smoking and drinking upon fetal performance. Well, once you have a patient in front of you who's an alcoholic, the typical patient that I thought alcoholism was all about is the kind of patient at the san Francisco General Hospital. Recent studies in our hospital have suggested that something in the order of 60-70 of all of our patients have alcohol or drug abuse problems at our hospital. Unfortunately, this kind of patient Is the minority of patients in large surveys. This kind of alcohol drug abusing patient makes up less than two of all the people who really have alcohol problems. This is perhaps the most important thing, which I'll say today, because if you start using drug treatment for this kind of patient, you'll conclude that it's a failure every time it would be analogous to trying to have a discussion today of cancer and use leukemia and acute plastic crisis and talk about the treatment of cancer because you'd be seeing the same kind of results. And this is why many of us have felt that it's it's a dismal failure to ever intervene in anyone smoking drinking or obesity problem, because addictions have only been diagnosed and clearly faced by the medical community at this stage. In fact, the vast majority of people who are alcoholics are like all the people here, and in fact, I've listed for you on your handout the key issues that usually present for middle class people who have alcohol related problems. A recent survey suggests that the best person to ask about somebody's drinking habits is not the patient himself. A better person is to ask the spouse, the employer or a significant other is the key term today when you find someone who's drug overdose, you should suspect that the person has an alcohol problem in the background. Every there's a linear relationship between the total amount of alcohol consumed and the uric acid. In fact, there are many, many more people in society who have alcoholism to account for their elevated uric acid than the disease gout. It's much more common to have people have a mild elevation of uric acid and have this related to alcohol. The cholesterol is often elevated an alcoholic patients and there may be a predisposition to elevate the the cholesterol and people with Type two hyper baited life of protein anemia, diabetic problems, seizure disorders, the whole host of gastrointestinal diseases which all of you are familiar with, especially peptic ulcer and gastric ulcer diseases. Dermatologists are now for the first time recognizing that chronic skin conditions, which don't appropriately hell under the usual medical therapy should be suspected. The person having heavy alcohol intake, an M. C. V. Greater than 100 occurs in almost all the patients in our hospital. And we recognize that mild folate deficiency is extremely common uh in alcoholic patients for practical purposes. Whenever you have a heavy smoker, you should immediately suspect that he's an alcoholic because these two processes are intimately linked abnormal liver functions, the psychological difficulties. I stress all of this for you only to tell you that the kind of alcoholic who's most likely to benefit from treatment is not someone who appears as a skid row public inebriate. He's never going to come to you saying I'm an alcoholic. Help me instead. Your diagnostic acumen for this problem has got to be great. I've listed for you two ways in which we're very concerned about alcoholism in our society, namely, the fact that there are only two diseases in modern medicine that are dramatically increasing in frequency. Uh, well actually, there are three venereal diseases certainly wanted to increasing in frequency. But the two major ones that concern us are cirrhosis of the liver and death and violence. Both of these have been intimately related to the total alcohol consumption in our society. I'm not going to specifically discuss the liver disease process today, although I have listed the key references for you, but I'd like to spend a moment and tell you how violence has been associated perhaps how this alcohol. For instance, recently in the newspaper has been called the violent connection. You'll see how it's been difficult to draw this conclusion, That the incidence of deaths and violence has gone up 100 from 1960 to 74, whereas cancer has decreased one and cardiovascular diseases have decreased 7%. There are country leads the way with the greatest risk of dying and murder. And in fact in traffic accidents today, 70 of all the fatal accidents in California occur with the driver, the person dying having the equivalent of three cocktails in his blood. Much of this has been related to television because in fact, I put this in specifically because of the hearings which are going on now and where this is being widely discussed. The average high school senior by the time he graduates has seen 15,000 hours of television and only 11,000 hours of class. Our he's seen 18,000 murders. Um, and that there are, there are six times more violence in the child hours than an adult hours. And the recent information, which is the most disturbing is that ads related to alcohol and cigarettes are intimately tied into this. Keep peak time of young viewers. Now, obviously you can see how loose this is. We're not certain about this, we're not sure which comes first. But in fact, this kind of behavior is often one of the physician is asked to deal with and you should suspect alcohol use. Well, this all sets in motion the uniqueness of the alcohol problem for us, namely that alcohol is the most common sedative hypnotic drug that patients take. It's a food, it's a legal drug, 90 of us use it and fortunately relatively few, namely 10 abuse it. I'll be discussing with you briefly the kinetics of alcohol, which are also unique. There are clear health hazards, especially related to liver gastrointestinal disease, perhaps neurological disease, and alcohol is a singer most common drug interacts with all other drugs. On the other hand, we have a $32 billion $10 billion dollars a year in taxes and that alcohol is the single drug Which has not increased in cost over the past 20 years. In fact, alcohol costs less today, considering inflation than any other substance in modern economy, Less than one of all the tax dollars that are collected or return to us to assist us to care for people that have these problems or to do research about it. There's tremendous advertising for it. We have virtually no medical insurance which will allow us to deliver health care to these people. And we currently have zero population growth, which more and more people at younger and younger ages are consuming more and more alcohol. And result is that that we are expecting and some have already said we are seeing more and more medical complications of alcoholism at younger and younger ages. The incidents of cirrhosis is perhaps the best marker of this and there is debate what the incidents of cirrhosis is really decreasing is actually occurring at a younger age. I should stress for you that it's never a threat for us to treat that most visible alcoholic. It never has been a threat. But in terms of the overall approach for our patients, if we actually did something about altering the smoking and drinking behavior of our patients, there would be tremendous economic problems. Well, based on all of this, how do you diagnose an alcoholic? What's an alcoholic, 1972, the National Council and Alcoholism got together and said, this is what an alcoholic is. These criteria are re evaluated in this week's journal the American Medical Association, in which the members of the american Society and alcoholism have agreed that these criteria clearly tell us the people who are alcoholics, people are alcoholics and you can remember them by W. A. S. P. You are an alcoholic if you drink enough alcohol so that when the drug is stopped, you have severe tremor hallucinations, seizures of the DTs. You are also an alcoholic if you have a high blood levels of the drug alcohol and are not affected by it or have a high level at any time. As an example, The average blood alcohol level in an average sized person goes up 30 mg per cent with a single drink on an empty stomach. So as an example if I had five gin and tonics in front of me And I consumed them. Now in one half hour I would have a blood level of alcohol of 150 mg per cent. And at that time if I were able to stand up here and be on one ft unassisted or touch my nose with my eyes closed or walk a straight line. If I could do those things I would be tolerant to the drug alcohol, I would be addicted to the drug alcohol and I would clearly be an alcoholic. If I had 300 mg per cent anytime anywhere I would be an alcoholic. It's of note that some hospitals are removing some of the worthless tests they have on there S. N. A. Panels and including a blood alcohol level. They have found huge numbers of people entering their hospital with elevated levels of alcohol. The p criteria is the pathology of alcoholism which I'm sure most people are familiar with. And the s criteria is the psychological one the one that's most difficult, which says that you're an alcoholic if you drink in spite or despite strong medical or strong social contraindications. What this means for practical purposes is that a patient has recurrent pancreatitis, has epilepsy or diabetes or hypercholesterolemia. The physician recognizes that the alcohol contributes to this. In some way. He says that alcohol contributes you should not be drinking. And despite the knowledge that these are related to the patient continues to consume the drug, alcohol he drinks in spite of strong medical contraindications in the military, there often social contra indications he's in trouble in the military service for somewhere, another. He's warned about this and the problem continues. Now. Some of the greatest progress in the field of alcoholism has been that all of these criteria have been relatively subjective and we've been very anxious to come up with objective medical criteria of blood level. Something that would clearly give us indices for alcoholism and acid AL to hide. And amino acids in the plasma have been this uh this slide comes from the reference by labor, which is on your liver slide on the ah liber liver reference. And in in this circumstance, it just illustrates the metabolism of alcohol. Alcohol is metabolized in the body to acid alga hide and acid Alga hide is the newest metabolic concern of people in the field of alcoholism. In fact, one, well, in fact, some people have suggested, we've called alcoholism the wrong disease all these years. Instead, we should call alcoholism acid alcoholism because it looks as though the toxic effects of ethanol are clearly related to acid Aldo hide, especially in the liver process. So that many physicians have felt that maybe we could measure acid Aldo hide in in the in the blood and in the reference in the acid alga Hide section, uh, labor, did this and showed that in people who were given an alcohol infusion over several hours, that their level of acid Aldo hide was at this point, and 14 patients who were after the DTs, who were clearly alcoholics, um, would have a much higher blood level. And this has been related to factors that cause heart disease and liver disease. That acid alga hide itself acts back to destroy the mitochondria, which which are responsible for its own metabolism and a vicious cycle is set up so that the acid Aldo high levels rise. They damage the liver and other essential organs. And this accounts for the pathology in the field of alcoholism. Well, the problem is that you're not about to readily measure acid alga hide. It's been remarkably difficult. There's been controversy about it for years. Instead, simpler techniques have been developed in an attempt to arrive at a metabolic diagnosis of alcoholism And they are summarized in the December seven issue of science this year, which was not I sent in this outline before that time. But dr Charles, Lieber and others have attempted to identify specifically alcohol induced liver disease. And there seems to be a specific enzyme which is located in the liver, in the peri uh in the paddock vein area, which is called gluten meal trans Pep. Today's this enzyme seems to be elevated in alcohol related liver disease. And if you initially measure that enzyme and then related to a unique amino acid called alpha amino n. Butyric acid, which accounts for the A. Here and related to another amino acid loosen in the plasma. And you take this two step approach of measuring glutamine trans Pep today's, which is a simple test and the relatively simple test of measuring this unique amino acid that's increased in the plasma. There is a dramatic association for the diagnosis and for the medical complications of alcoholism. We don't exactly know how early this comes on. It doesn't go away immediately, but we do know that this is probably a metabolic marker for the diagnosis of alcoholism. Whether the typical alcoholic that we've discussed will have this or not, it seems quite likely in the in the early studies by labor. Now, one of the things that we've attempted to do, which I just thought I'd mention in passing is that one thing certain about alcoholics is they drink too much and then if you ask someone how much they drink, patients often don't tell you, so that we've set up a method to measure how much people are drinking. Um, and it turns out to be something and I'd be happy to discuss this with you. As simple as a waterproof pad that's connected and placed on the skin and worn by the patient for eight days. Uh You'll see this published shortly and what actually happens is easier placed on the lower extremity. The patient drinks whatever they wish. Um It looks something like this. They wear it down here. I'm a long distance runner and I've worn these for several weeks. They don't seem to cause difficulty. Uh, alcohol is freely def usable into water, and since we're collecting sweat, you can spend it in a centrifuge injected without going into it in great detail. There's a very definite relationship between the amount of alcohol consumed in very low doses and the amount that's consumed by alcoholic people drinking on our metabolic ward. Uh if you just measure the square root of the amounts of alcohol that you detect, this is very helpful to us because in fact, we will now know exactly how much somebody's drinking over time and more importantly, will be able to design therapeutic a therapeutic endpoint, which will allow us hopefully to look at whether certain drugs are really useful in the treatment of alcoholism. Well, what is the treatment of alcoholism? Well, the first thing that you do in the treatment of all addictions, and I'll be discussing this for this afternoon was it relates to narcotics, is that the first treatment is called detoxification. And detoxification means ridding the body of the drug alcohol so that there are no medical complications of withdrawal When it comes to sedative hypnotic drugs. The fear of detoxification is seizures and hallucinations, and any sedative hypnotic drug, Valium, Librium barbs will cause seizures and hallucinations if they have been taken in high enough doses for long enough periods of time. This is the most difficult thing that we attempt to do because we used to think that detoxification periods lasted only a few days that people sobered up in a couple of days. We now recognize a detoxification from drugs as a whole. It takes much longer than we previously recognized that people who are smokers and the people who are drinkers require many months before their sleeping patterns are normal and before they feel normal. And during the time in which we detoxify them, we looked for medical complications, psychiatric problems and multiple drug abuse. And then we set up a system of modifying their behavior about the drug over a long period of time. I've listed for you some of the specifics without going into it in great detail as the time is short in the area of addictions, the group experience is by far the best that the one on one psychodynamic psychoanalytical processes have not been useful in the area of addictions. The psychotherapeutic approach has not been as useful as the group experience. And no matter how you go about modifying behaviour, it's essential to recognize that there is often a person involved with the alcohol smoking or eating behavior in addictions and that that person has to be brought into the treatment as well. Now, what is from a practical point of view, the clear areas where drug treatments are useful in the one area, for sure, is that we can alter the withdrawal syndrome from alcohol and we can alter the withdrawal syndrome from any sedative hypnotic drug by the basic principle of substituting a longer acting medicine for the short acting medicine that the patient is abusing and tapering this over time and just to refresh your memory. This is from our textbook in the field of alcoholism that They're. The typical alcohol withdrawal occurs 8-10 hours after the alcohol is stopped. There's tremor increase in blood pressure, increase in pulse respiration and temperature. Some people will hallucinate during this early period, Some will have fits, insomnia, mild disorientation. In mildest form. The alcohol withdrawal is a hangover and in most severe form it's a rum fit. This is part of the pharmacology of the sedative hypnotic drug, alcohol, it occurs with other drugs as well. The only difference would be the time course over which it occurs. So as an example, you often give a patient Valium the drug would be abruptly stopped and the patient will feel shaky, not 8 to 10 hours later, but 2 to 3 days later, then the patient will start drinking or taking more drugs and you'll be in the vicious cycle of treating them over and over again with medications, A more severe type of withdrawal that's familiar to all of you. It's called the DTs. This is delirium tremens. This is not specific for alcohol. We have it in our barbiturate addicts and in our placid ill addicts and and all of our other addicts as well who use sedative hypnotic drugs and I'm sure you're familiar with this syndrome. I've never seen the hallucinations be pleasant. Um They're just not pleasant. The idea of pink elephants is just not accurate. Well, how do you treat the DTs? And how do you treat alcohol withdraw? This is the drug and the family of drugs that we use. These are clearly the drugs of choice. These are benzodiazepine drugs. This is the basic benzodiazepine nucleus. There is diazePAM, Valium claudia's up oxide, Librium downing, LORazepam, cyrix oxes, apam and trans seen Cloris a pet. There are five benzodiazepines on the market and they are characterized more by their similarities than by their differences. Despite what many have discussed. And we know conclusively from the national cooperative study that was done in the DTs, that the benzodiazepine drugs are far superior in terms of the likelihood of decreasing convulsions and preventing uh DTs than are the final matthias scenes Thora zine here, which actually lowers the seizure threshold and make seizures more likely to occur as compared to placebo, fireman and visceral hydroxy scene in the annals of internal medicine. Was this classic review by Thompson, which took patients and compared diazePAM versus peralta hide. We've done a relatively similar studies and elegant study. They even put Peralta hide swabs under all the patient's bed so they would smell the same. And it concluded that with intravenous diazePAM uh five or 10 mg stack and five every five minutes until the patient is calm, calm, not comatose. Uh There's a big difference there uh and we stand at the bedside and administer diazePAM and we treat DTs readily with a lot fewer complications than any of the other medications. Now there are a few problems with benzodiazepines, one of which is outlined on this slide and that is you should not give them into muscularly. The benzodiazepine drugs, all of them are poorly absorbed from inter muscular sites. You can see that the plasma levels of the clear days up oxide in this case are much lower than the oral, the same dose of the oral drug. So avoid these particular drugs. Uh Inter muscularly. The usual story Is that you give 50 of Librium and 50 more and 50 more in the patient sleeps for a week and has aspiration pneumonia. You don't want to be treating acute withdrawal in that fashion. One of your biggest problems, of course, is you create this kind of issue, namely that you an attempt to treat withdrawal. You wind up getting valley aholic or a liberal aholic instead of an alcoholic. And you want to attempt to use benzodiazepine drugs in the largest dose at the least frequent interval if you're going to use them at all. And in general, it's better not to use these medications chronically and people who are already abusing alcohol or other medications. Now, this is the drug that for practical purposes should be given to almost all alcoholics. I give myself Iran to virtually every alcoholic that comes my way. Why? Because it's virtually impossible to work with a person who's drinking. They will not keep their appointments. They will not work with you in any way. You have no hope for practical purposes. This medication must be given in order to achieve a more prolonged period of detoxification. High sulphur in itself is a drug which blocks alcohols metabolism and causes patients to become ill if they consume alcohol along with the dye sulfur and the reaction is proportional to the amount of myself or am and the amount of alcohol so that I rarely give more than 250 mg. Instead, I usually give 100 and 25 mg and we usually give the medication at bedtime because there's slight sleepiness associated with it. Some countries France and Canada have mandated this treatment via the court system, have been implanted it in people's rear ends uh in their attempt to treat alcoholics. This medication does three things for you. That is a value in the treatment of alcoholism. Number one. This medic medication is only useful in the treatment of alcoholism so that it's called anti abuse and it can't be confused with depression or anxiety or anything else. So you get very clear with the patient that they can't deny this problem, namely that you're an alcoholic and you're different. The second thing is you can't possibly take this drug and drink so that you achieve a more prolonged period of detoxification. And finally, and perhaps most importantly, that without some motivation on the part of the patient to modify their addiction, you don't have any chance at all in this process and that the sulfur and becomes the best way to check the motivation for the patient to take the medication and what we've done now we've published is to set up a method, a simple method of measuring compliance. We're able to measure this drug and blood, breath and urine. This happens to be one of our clinic patients. We just have a given amount of C. 02 that's breathed uh through this female failing. And we collect carbon di sulfide which is one of the metabolites of diesel from the patient blows into it until the color turns clear. And then you'll note that this patient was taking his Antabuse. There's a definite yellow color. This costs very little to run this test and you find out that many people who claim to be taking interviews are in fact not taking it. You also find out that many people that complain of the side effects of this medication in fact aren't taking it so that when they say that there is impotence, yes, I'm impotent taking Antabuse which must be extremely rare in my experience. They never were taking the medication in the first place and impotence is very high frequency amongst alcoholic patients in general. Well, a prospective study, I wanted to also mention to you that there are many sources of alcohol and I want to remind you that we had some physicians prescribing Alex offline and Antabuse together and wondering why the patients were having Antabuse reactions when they weren't drinking. I've had the opportunity to prepare a booklet for the patients and um this is free to anyone who wishes to get this from your sales representative. Um It's my personal feeling that our patients should know as much about any medication that they're taking. And I give this book prior to giving the patient a prescription so that they will know everything that they need to know about deciding to take this medication. It is written for the patient, not for the doctor. I recommend that if you use and abuse that you can have these in your office and you give them to the patient. Finally, I wanted to mention to you that we now have a prospective study underway using our patches as an endpoint for the alcohol consumption and using the drug lithium, which was shown in this one study to be a great value in the skid row public and every population in preventing hospitalization in chronic alcoholics. Well, to conclude this this part, I just wanted to relate to you that we've reviewed the issues about alcohol from psychological and physical point of view and all of this. I had the opportunity to write in in Time magazine. I was very happy to do this because um I think you can appreciate that in addition to a medical issues involved with alcoholism, you obviously appreciate the social and psychological implications of this. I might also add that I'm not an alcoholic and that no one in my family's ever been an alcoholic, but I've certainly felt the pressure on myself treating these kinds of patients and their sort of Laos um if you will. So I was kind of happy to prepare this. And unfortunately when the article was published, um there were everything that I had said had been removed And they were 14 ads extolling the virtue of alcohol, including this one suggesting that what mother needs for mother's day is Harvey's Bristol cream. Um it's, if you will, it's the problem and that sort of summarizes it for me exactly what many people have felt all along, that we paid a great deal of lip service to this in some way.
