We conducted an open-label, dose escalation trial of disulfiram in men with non-metastatic recurrent PCa after local therapy. Dose escalation occurred if a demethylating 'response' (that is, 10% decrease in peripheral blood mononuclear cell (PBMC) global 5-methyl cytosine (5(me)C) content) was observed in <3 patients in cohort 1. Cohorts 1 and 2 received disulfiram 250 mg and 500 mg daily, respectively. The primary end point was the proportion of subjects with a demethylation response. Secondary end points included the rate of PSA progression at 6 months, changes in PSA doubling time and safety/tolerability.

A diverse group of compounds inhibit the action of chemical carcinogens when administered prior to and/or simultaneously with the carcinogen. The inhibitors include naturally-occurring constituents of foods as well as synthetic compounds introduced into the environment. Three general mechanisms of inhibition exist. The first, illustrated by disulfiram inhibition of dimethylhydrazine-induced neoplasia of the large bowel, is the direct blocking of enzymatic activation of the carcinogen to its reactive ultimate carcinogenic form. The second mechanism of inhibition entails the stimulation of a coordinated detoxification response which results in increased activity of detoxifying enzymes in the microsomes and also the cytosol. At least two subdivisions of this response occur. One, for which butylated hydroxyanisole is a prototype, shows enhanced activity of some microsomal enzymes but not aryl hydrocarbon hydroxylase (AHH). However, it does have a rapidly active component which results in marked alteration of microsomal metabolism of benzo(a)pyrene. Another, for which a prototypical inhibitor is beta-naphthoflavone is characterized by induction of increased AHH activity. The third general mechanism of carcinogen inhibition entails the direct scavenging of reactive carcinogenic species by the inhibitor. Evidence supporting the psosibility that inhibitors play a role in the response of humans to carcinogens consists of three types. The first is the chemical diversity of the inhibitors and their actual occurrence in the environment. The second is the resposiveness of the detoxification systems, particularly those in the tissues of the major portals of entry, to the naturally-occurring or synthetic inhibitors. The third is a group of epidemiological studies which suggest that individuals consuming relatively large quantities of vegetables, a major source of naturally-occurring inhibitors, are at lower risk from gastrointestinal cancers.

In the last years, numerous studies have been performed on neurobiological mechanisms in alcohol craving. Changes in the hypothalamic cortisol pathway and the leptin metabolism, which is also associated with pharmacological interventions, have been of special interest. With acamprosate and naltrexone two substances exist for pharmacotherapy, but recent results about the efficacy are controversial. The clinical profit of disulfiram has been shown, at least in a subgroup of patients. Besides, there are several promising candidate substances. Current investigations focus on a differentiated pharmacotherapy of alcohol dependence, including psychological and genetic factors.

A 37-year-old female subject had been convicted of driving under the influence of alcohol, and 19 months later, claimed abstinence after supervised disulfiram treatment. Our aim was to elucidate the value of direct ethanol metabolites as measures of abstinence. Ethyl glucuronide (EtG) and fatty acid ethyl esters (FAEE) in hair, phosphatidylethanol in whole blood and EtG and ethyl sulphate in urine were measured. The results were compared with self-report of alcohol consumption and traditional blood biomarkers for chronically elevated alcohol consumption as carbohydrate deficient transferrin (CDT), gamma glutamyl transpeptidase, mean corpuscular erythrocyte volume, aspartate aminotransferase and alanine aminotransferase. EtG was found in distal parts of hair only, whereas the proximal parts were negative. Furthermore, FAEE concentrations were found in the typical distribution over the hair length and showed values typical for either moderate social drinking or abstinence. CDT was above cut-off in 9 out of 16 analyses with a decreasing tendency and the lowest values in the last 2 months before the end of sampling. The data suggest that in addition to traditional markers, a combination of direct ethanol metabolites can be useful in the expert assessment of judging driving ability. A careful individual interpretation of the results for the different markers, however, is an absolute necessity.

Drug addiction is a serious disease with damaging effects on the brain and physical health. Despite the increase in the number of affected individuals, there are few effective pharmacological treatment options for substance use disorders. The study of the influence of an individual's genetic features on the treatment response may help to identify more efficacious treatment options. This systematic review focuses on the serotonergic system because of its relevant role in mood and impulse control disorders, and its contribution to the development and maintenance of drug use disorders. In particular, we examine the role of serotonergic genes in the response to pharmacotherapy for alcohol, cocaine and nicotine addiction. Current evidence suggests that genetic variability of the serotonergic biosynthesis enzyme tryptophan hydroxylase 2 (TPH2) and the serotonin transporter (SLC6A4) genes mediates the efficacy of several addiction treatments, such as ondansetron and disulfiram, and the antidepressants bupropion, nortriptyline and sertraline.

In an effort to examine the placebo, psychological deterrent, and pharmacological deterrent effects associated with implanted disulfiram, subjects were given either disulfiram implants or sham operations. Ethanol challenges elicited no disulfiram-ethanol reactions (DERs), indicating that at the time of the challenge neither a pharmacological deterrent nor a placebo effect was operating. Of the patients who resumed drinking, only those with disulfiram implants experienced DERs. Sham operation subjects continued to drink after their first post-challenge drink; four of five disulfiram implant recidivists remained abstinent following their experience of a DER. It is concluded that the pharmacological deterrent effect of the disulfiram implant may have been underestimated in previous reports.

Shock is a common reason for medical intensive care unit admission, with septic and cardiogenic accounting for most of the etiologies. However, the potential severity of adverse side effects of drugs indicates that any medication should be carefully scrutinized for potential pharmacokinetic and pharmacodynamic interactions that may result. We herein report the case of a life-threatening shock mimicking successively anaphylactic, cardiogenic, and septic shock, which was finally related to disulfiram ethanol reaction. Indeed, disulfiram ethanol reaction is known to provoke unpleasant symptoms through vasodilatation in various organs. However, extreme manifestations of vasodilatory shock may lead to circulatory failure and lactic acidosis. Because of large prevalence of alcoholism and disulfiram medication, emergency physicians and medical specialists should be aware of this life-threatening condition, with its misleading presentation.

Disulfiram and bis-(4-methyl-1-homopiperazinylthiocarbonyl)-disulphide (FLA 63) markedly inhibited the Mg2+/ATP-dependent uptake of various monoamines, e.g. dopamine (DA), by isolated membranes of bovine adrenal chromaffin granules. Both compounds affected DA-beta-hydroxylase (DBH) activity more markedly than the uptake of DA. Other inhibitors of DBH, e.g. fusaric acid and diethyldithiocarbaminate (DDC), did not interfere with DA uptake. Disulfiram and FLA 63, in contrast to fusaric acid and DDC, also caused a partial inhibition of Mg2+-dependent ATPase. It is concluded that the inhibition of monoamine uptake by disulfiram and FLA 63 is not related to their effect on DBH.

The study was designed to elucidate the basic pharmacological and biochemical effects of the disulfiram dose (Antabus) provoking disulfiram-alcohol reaction (DAR) in 52 human volunteers after ethanol challenge. Disulfiram was given daily in increasing doses (1, 100, 200, and 300 mg) in successive 14 day periods, with ethanol challenge at the end of each period, until a DAR was achieved. Irrespective of dose (except the 1 mg dose), the DAR was always accompanied by almost complete inactivation (about 97%) of aldehyde dehydrogenase (ALDH) activity in erythrocytes, plasma concentrations of diethyldithiocarbamic acid methyl ester (Me-DDC) in the range of 8-472 nmol/l and accumulated plasma concentrations of acetaldehyde in the range of 7-197 mumol/l. In four of the volunteers, the cardiovascular effects of the DAR were recorded as a decrease in diastolic blood pressure (14-47 mmHg) and an increase in pulse rate (9-40 beats/min.), accompanied by a two- to fourfold increase in the plasma concentrations of adrenaline and noradrenaline. The enzyme kinetics of ALDH in erythrocytes were regularly analysed in eight volunteers during DSF intake. In addition to the expected decrease in oxidizing capacity, the Km values were also impaired, which suggests that the inhibitor is implicated in an active site directed reaction.

Case 1: At the end of two months of treatment with disulfiram 250 mg/day, a 31-year-old woman complained of weakness in distal segments of the lower limbs associated with burning dysesthesias, numbness and pain in the soles of the feet and the legs below the knees; bilateral walking steppage, reduction in foot strength, absence of ankle jerk and knee tendon reflexes, and tactile stocking pin-pick and vibratory sensory impairment in the lower limbs below the knee. Disulfiram was discontinued and she recovered partially over three months. Case 2: After one month of treatment with disulfiram 1600 mg/day, a 27-year-old man reported walking impairment, distal lower limb weakness and paresthesias. He had unsteady gait with bilateral steppage and foot drop, absence of ankle jerks and overall sensation impairment below the knee. Disulfiram was discontinued and nine months later there was almost complete recovery of motor deficits, only minor motor weakness in distal leg muscles, and no dysesthesia, sensation deficits or areflexia. In both of them clinical and neurophysiological patterns were indicative of a distal axonopathy. DISCUSSION The mechanisms by which disulfiram cause injury in human nerves are unclear, though may involve carbon disulfide. The discrepancy between experimental and clinical observations is still unexplained.

20 elective surgical patients received either disulfiram (500 mg orally, n = 10) or nothing (controls, n = 10) the night before surgery. Disulfiram, converted in vivo to an effective inhibitor of P450 2E1, was used as a metabolic probe for P450 2E1. All patients received standard halothane anaesthesia (1.0% end-tidal, 3 h). Blood halothane and plasma and urine trifluoroacetic acid, bromide, and fluoride concentrations were measured for up to 96 h postoperatively.

A three-way crossover study was undertaken in 10 healthy subjects to characterize the reported disulfiram-like activity of moxalactam and to assess its influence on ethanol and acetaldehyde metabolism. On different occasions separated by at least 2 wk subjects were given in random order: 0.5 gm/kg ethanol orally, 0.5 gm/kg ethanol followed in 1 hr by 1.0 gm IV moxalactam, and 1.0 gm IV moxalactam every 8 hr for four doses followed by 0.5 gm/kg ethanol. Mean ethanol elimination rates of 13.1 +/- 0.76, 10.1 +/- 1.11, and 10.9 +/- 1.06 mg/dl/hr (mean +/- SEM) were observed in the three protocols, respectively. Corresponding mean estimated acetaldehyde clearance rates were 103.7 +/- 15.55, 92.8 +/- 13.79, and 97.3 +/- 10.41 l/min (mean +/- SEM). While no consistent moxalactam effect on ethanol or acetaldehyde elimination was observed, two subjects experienced mild disulfiram-like reactions to ethanol after moxalactam pretreatment. In one subject this reaction was associated with markedly elevated blood acetaldehyde concentrations. We conclude that moxalactam pretreatment may induce a disulfiram-like reaction after ethanol ingestion in some, probably due to inhibition of aldehyde dehydrogenase, and that alcoholic beverages are contraindicated in patients receiving moxalactam. We suggest, however, that such reactions will not occur when moxalactam is given after ethanol ingestion.

The intraerythrocyte calcium concentration in blood samples of 42 hospitalized alcoholic subjects was initially elevated but declined over a period of several weeks toward normal values. The abnormally high values, which appear to be a direct consequence of prior alcohol ingestion, may explain previous reports of lowered erythrocyte potassium in chronic alcoholics, since there is a specific calcium-gated potassium channel in erythrocyte membranes.

We studied the omega-oxidation of docosanoic acid (C22:0) in rat liver microsomes. C22:0 and 22-hydroxy-docosanoic acid (omega-hydroxy-C22:0) were used as substrates, and the reaction products were analyzed by electrospray ionization mass spectrometry. In the presence of NADPH, omega-oxidation of C22:0 produced not only the hydroxylated product, omega-hydroxy-C22:0, but also the dicarboxylic acid of C22:0, docosanedioic acid (C22:0-DCA). When rat liver microsomes were incubated with omega-hydroxy-C22:0 in the presence of either NAD+ or NADPH, C22:0-DCA was formed readily. Formation of C22:0-DCA from either C22:0 or omega-hydroxy-C22:0 with NADPH as cofactor was inhibited strongly by miconazole and disulfiram, whereas no inhibition was found with NAD+ as cofactor. Furthermore, omega-oxidation of C22:0 was reduced significantly when molecular oxygen was depleted. The high sensitivity toward the more specific cytochrome P450 inhibitors ketoconazole and 17-octadecynoic acid suggests that hydroxylation of C22:0 and omega-hydroxy-C22:0 may be catalyzed by one or more cytochrome P450 hydroxylases belonging to the CYP4A and/or CYP4F subfamily. This study demonstrates that C22:0 is a substrate for the omega-oxidation system in rat liver microsomes and that the product of the first hydroxylation step, omega-hydroxy-C22:0, may undergo further oxidation via two distinct pathways driven by NAD+ or NADPH.

Diagnosis of alcoholism requires a vigilant attitude and aggressive pursuit of supporting evidence by the primary care physician. Because the alcoholic is characteristically defensive and commonly denies the diagnosis, the physician must be persistent and honest when confronting the patient. Effective treatment is available through programs comprising patient and family education, psychotherapy, medical supervision, involvement in Alcoholics Anonymous, use of disulfiram (Antabuse), and follow-up care. Since the recovering alcoholic is vulnerable to relapse, long-term maintenance of sobriety requires not only abstinence from alcohol but also avoidance of psychoactive and narcotic drugs.

The community reinforcement approach (CRA) has been applied in the treatment of disorders resulting from alcohol, cocaine and opioid use. The objectives were to review the effectiveness of (1) CRA compared with usual care, and (2) CRA versus CRA plus contingency management. Studies were selected through a literature search of RCTs focusing on substance abuse. The search yielded 11 studies of mainly high methodological quality. The results of CRA, when compared to usual care: there is strong evidence that CRA is more effective with regard to number of drinking days, and conflicting evidence with regard to continuous abstinence in the alcohol treatment. There is moderate evidence that CRA with disulfiram is more effective in terms of number of drinking days, and limited evidence that there is no difference in effect in terms of continuous abstinence. Furthermore, there is strong evidence that CRA with "incentives" is more effective with regard to cocaine abstinence. There is limited evidence that CRA with "incentives" is more effective in an opioid detoxification program. There is limited evidence that CRA is more effective in a methadone maintenance program. Finally, there is strong evidence that CRA with abstinence-contingent "incentives" is more effective than CRA (non-contingent incentives) treatment aimed at cocaine abstinence.

Desmoplasia in human pancreatic cancer (PC) promotes cancer progression and hinders effective drug delivery. The objectives of this study were to characterize a homologous orthotopic model of PC in Syrian golden hamster and investigate the effect of anti-fibrotic (pirfenidone), antioxidant (N-acetyl cysteine, NAC) and anti-addiction (disulfiram, DSF) drugs on desmoplasia and tumor growth in this model. The HapT1 PC cells when implanted orthotopically into hamsters formed tumors with morphological, cellular and molecular similarities to human PC. Protein profiling of activated hamster pancreatic stellate cells (ha-PSCs) revealed expression of proteins involved in fibrosis, cancer cells growth and metastasis. Pirfenidone, suppressed growth of HapT1 cells and the desmoplastic response in vivo; these effects were enhanced by co-administration of NAC. Disulfiram alone or in combination with copper (Cu) was toxic to HapT1 cells and PSCs in vitro; but co-administration of DSF and Cu accelerated growth of HapT1 cells in vivo. Moreover, DSF had no effect on tumor-associated desmoplasia. Overall, this study identifies HapT1-derived orthotopic tumors as a useful model to study desmoplasia and tumor-directed therapeutics in PC. Pirfenidone in combination with NAC could be a novel combination therapy for PC and warrants investigation in human subjects.

For nearly 20 years, disulfiram implanted subcutaneously, has been used in alcoholics who have failed to respond to other treatment. Significantly positive results have been reported in a large number of cases. Despite this extensive use, many questions remain as to how these effects are exerted. As the reaction to alcohol following disulfiram implantation occurs less frequently and in lower intensity than following oral ingestion, psychological mechanisms probably play a vital role. Based in part on out own recent series of cases, the following explanations are offered regarding the possible mechanisms of action: (1) high motivation to stop drinking is manifested by agreeing to the precedure and reinforced by the procedure; (2) palpable presence of hte drug in the site of implantation; (3) generally sufficient reactivity of the agent to indicate activity to the patient;(4) in obsessional patients there is a removal of the fear of resumption of drinking for an extended period of time. For the more sociopathic patients the implant appears to provide a more structured ego boundary to allow the patient to change.

antabuse drug information

Disulfiram (DSF) is a drug used in aversion therapy to treat alcoholics and acts by inhibiting mitochondrial low-K(m) aldehyde dehydrogenase. Investigations into the mechanisms for in vivo inactivation suggest that the DSF metabolite S-methyl-N, N-diethylthiocarbamate sulfoxide reacts irreversibly with an active site Cys. This work aimed to determine if DSF generates monothiocarbamate adducts on cysteine residues in vivo by examining hemoglobin. Sprague-Dawley rats were treated with DSF po for 2, 4, and 6 weeks. Rats have four different globin beta-chains, of which three (beta-1-3) contain two cysteine residues each. MALDI-TOF MS analysis of two new globin species from DSF-treated rats collected by HPLC revealed increments of 99 Da above the mass of the unmodified chains (beta-2 and beta-3). In a separate experiment, the globin mixture was digested for 2 h with Glu-C and reanalyzed by MALDI-TOF MS. Results showed a peptide at m/z 2716.3 having a mass 99 Da higher than a known Cys-containing peptide. Subsequently, the Glu-C digest was analyzed using Q-TOF tandem MS, enabling observation of the +4 charge state of the peptide with m/z 2716.3. This peptide was fragmented to produce y-sequence ions that located the modification to Cys-125 (present on both beta-2 and beta-3). Cys-125 is the most reactive of two cysteine residues on these beta-chains. To confirm the structure of the modification, globin was hydrolyzed with 6 N HCl at 110 degrees C for 18 h. The adduct survived these conditions so that S-(N,N-diethylcarbamoyl)cysteine was detected in the hydrolysates of treated rats on the basis of comparison with the tandem MS spectrum of a standard. These results extend the findings of others obtained using glutathione conjugates and demonstrate the ability of DSF to covalently modify Cys residues of proteins in a manner consistent with the production of S-methyl-N, N-diethylthiocarbamate sulfoxide, or sulfone, intermediates.

Previous metabolic studies in rats have suggested in vivo formation of the acrolein-glutathione (acrolein-GSH) adduct following administration of the highly reactive alpha, beta-unsaturated aldehyde acrolein. Early studies by several investigators demonstrated that similar compounds such as alpha, beta-unsaturated aldehyde-cysteine adducts have toxic (carcinostatic) activity against Ehrlich ascites tumor cells implanted in mice. The current studies investigated the in vivo toxicity associated with the acrolein-GSH adduct in the male Sprague-Dawley rat. The 1:1 acrolein-GSH adduct was synthesized and characterized by physical-chemical methods. Rats given the acrolein-GSH adduct intravenously at 0.5 or 1 mmol/kg developed nephrotoxicity characterized by glucosuria, proteinuria, elevation in serum urea nitrogen, and gross and histologic changes of the kidney. The toxicity was not affected by pretreatment of rats with pyrazole, an alcohol dehydrogenase inhibitor; disulfiram, an inhibitor of aldehyde dehydrogenases; or probenecid, a renal organic anion transport inhibitor. Administration of a similar but nonaldehydic glutathione conjugate, S-n-propylglutathione, did not result in nephrotoxicity in the rat. The nephrotoxicity induced by the acrolein-GSH adduct was inhibited by acivicin, a gamma-glutamyl-transpeptidase inhibitor. These results indicate that the acrolein-GSH adduct requires processing through the first step of the renal mercapturic acid synthesis pathway to be activated to a toxic species.

The metabolism of biogenic aldehydes was measured in different fractions of human blood. Isolated erythrocytes, leukocytes, platelets and plasma were incubated with the aldehydes derived from dopamine and serotonin (DOPAL and 5-HIAL, respectively). The disappearance of the aldehydes and the formation of the acid and alcohol metabolites were analysed using HPLC with electrochemical detection. When erythrocytes were incubated with 1 microM DOPAL or 5-HIAL only the acid metabolites were formed, whereas both acid and alcohol metabolites were formed in incubations with leukocytes or platelets. No metabolites were formed when the aldehydes were incubated with plasma. In incubations with erythrocytes, the oxidation of the aldehydes was totally inhibited in the presence of 50 microM disulfiram, whereas the formation of both acid and alcohol metabolites was inhibited in incubations with platelets. Disulfiram did not affect the metabolism of DOPAL or 5-HIAL in incubations with leukocytes. The oxidation of the aldehydes was inhibited by 50-70% in the presence of a 500-fold excess of acetaldehyde. Ethanol at a concentration of 10 mM did not affect the metabolism.

Cancer cells, characterized by local invasion and distant metastasis, are very much dependent on the extracellular matrix. The expression of matrix metalloproteinases (MMPs) has been implicated in the invasion and metastasis of cancer cells. In this study, we reported the effects of disulfiram, a clinically used anti-alcoholism drug, on tumor invasion suppression, as well as its effects on the activity of MMP-2 and MMP-9 in human osteosarcoma cells (U2OS). Disulfiram has been used for alcohol aversion therapy. However, recent reports have shown that disulfiram may have potential in the treatment of human cancers. Herewith, we showed that the anti-tumor effects of disulfiram, in an invasion assay using U2OS cells and that disulfiram has a type IV collagenase inhibitory activity that inhibits expression of genes and proteins responsible for both cell and non-cell mediated invasion on pathways. In conclusion, disulfiram inhibited expression of MMP-2 and MMP-9 and it regulated the invasion of human osteosarcoma cells. These observations raise the possibility of disulfiram being used clinical for the inhibition of cancer invasion.

Crush injury to the sciatic nerve resulted in a significant impairment of functional response which gradually recovered over a period of 22 days. Treatment of animals with DEDC caused a significant delay in functional recovery which was accompanied by poor histo-logical and electrophysiological outcome. Prooxidant effect of DEDC is quite evident from a significant decrease in vitamin E levels in both injured and uninjured sciatic nerves.

We found significantly higher FSS levels in patients with a current partnership. No significant influence was found of the FSS on days until relapse and retention time. However, FSS was positively correlated with cumulative abstinence. In comparison with another patient sample, it can be shown that the patients of the close-meshed biopsychosocial treatment program seemed to perceive more FSS, presumably through the higher frequency of the outpatient treatment contacts.

The inhibition of the low-Km, rat-liver mitochondrial aldehyde dehydrogenase (ALDH) by the alcohol-sensitizing agents cyanamide, 1-aminocyclopropanol (ACP) and disulfiram was studied in vitro. All three compounds caused a progressive decline in the enzyme activity. Restoration of activity could not be achieved by gel-filtration, dilution or by the addition of excess thiol. High concentrations of acetaldehyde partly restored the activity of the cyanamide-inactivated enzyme but had no effects on the disulfiram- or ACP-inactivated enzyme. In the presence of saturating concentrations of the coenzyme (NAD+), the inactivation process followed first-order kinetics at fixed concentrations of the inhibitors. Plots of the apparent first-order rate constants against inhibitor concentration were curved, suggesting the formation of saturable, reversible holoenzyme-inhibitor complexes prior to the covalent reactions. In the absence of NAD+, the rate of inactivation by disulfiram was biphasic and considerably higher than that in the presence of NAD+. In contrast, no inactivation was obtained with cyanamide in the absence of NAD+. Likewise, the presence of NAD+ greatly promoted the inactivation by ACP. The esterase activity of the enzyme was also affected by the inhibitors, although to a lesser extent than was the dehydrogenase activity. The results obtained suggest that all three inhibitors inactivate the enzyme through covalent reactions with the thiol groups at the active site. It is proposed that binding of NAD+ limits access of disulfiram to the thiols at the active site but provides a situation that favours an electrophilic attack of cyanamide and ACP on the thiol groups.

The authors report a case of symmetric multiple lipomatosis in a young woman with chronic liver disease caused by previous alcohol abuse whose onset occurred three years after the suspension of the toxic agent. The introduction includes a review of the latest literature, focusing in particular on the most probable etiopathogenetic causes, the most common clinical presentations and therapeutics choices. After a description of this particular case, the authors discuss the unusual presentation of the syndrome caused by the rapid onset of lipid accumulation a long time after the suspension of alcohol abuse.

Although disulfiram (tetraethylthiuram disulfide; DSF) has been used in the treatment of alcoholism for almost a quarter of a century, little is known about its in vivo metabolism. One reason for this is that few analytical methods are available that can determine DSF and its buy antabuse online various metabolites in biologic fluids and tissues. This article describes two simple procedures for the determination of these substances.

The published literature tends to buy antabuse online find that the outcome of mandatory treatment for alcohol dependence is no worse than that for 'voluntary' treatment. Supervised disulfiram has been shown to improve outcome in Court-referred patients. When offenders take treatment offered as part of probation or a deferred sentence, they choose to do so, rather than face a penalty. It is not a 'free' choice in the usual sense, but the outcome can be beneficial to the offender as well as to society and this helps to justify its use. Coping and social skills therapy have value, as probably have antipsychotic and antidepressant drugs in some cases. Supervised disulfiram has a role supported by controlled studies.

The halothane dose was similar in all groups. Methoxsalen decreased 0- to 8-h trifluoroacetic acid (23 +/- 20 micromol vs 116 +/- 78 micromol) and bromide (17 +/- 11 micromol vs 53 +/- 49 buy antabuse online micromol) excretion (P < 0.05), but not thereafter. Plasma F2-isoprostanes in controls were increased from 8.5 +/- 4.5 pg/ml to 12.5 +/- 5.0 pg/ml postoperatively (P < 0.05). Neither methoxsalen nor troleandomycin diminished reductive halothane metabolite or F2-isoprostane concentrations.

Fifty male alcoholics had serum dopamine-beta-hydroxylase (DBH) activity, and serum prolactin (PRL) levels measured on the day of withdrawal, and 22 of them also on days 7 and 28 after it. The obtained values were related to the development of withdrawal symptoms. Treatment was begun with meprobamate on the first day of withdrawal, and from day 7 it was completed with disulfiram (250 and 500 mg/day, respectively). Serum DBH activity decreased significantly by day 7, however a further fall of it occurred by day 28 only in patients receiving high doses (500 mg) of disulfiram. PRL levels rose over the period of withdrawal which reached significance level on day 28. No correlation was found between serum DBH activity and the severity of withdrawal symptoms. Serum DBH activity did not differ from that of the healthy controls at either point of time, while serum PRL level was significantly buy antabuse online elevated throughout the period of the study.

Disulfiram (DSF) can considerably alter the organotropy of chemical carcinogens. For N-nitrosodimethylamine and for N-nitrosodiethylamine the organotropy is shifted from the liver to the nasal cavity or the oesophagus, respectively. Whereas the influence of DSF or its metabolites on enzyme systems has been studied, little is known about its interaction with the carcinogens at a molecular level. Therefore, postulated buy antabuse online reaction products of a series of alpha-hydroxylated N-nitroso-dialkylamines and dithiocarbamate were synthesized and tested for mutagenicity in Salmonella typhimurium TA 1535. The results show that the compounds conjugated at a primary alpha-C-atom are not mutagenic, whereas those conjugated at a secondary alpha-C-atom are active. The primary N-nitroso-dithiocarbamates represent unique examples of inactivated dialkyl-nitrosamine derivatives. In addition, their formation in vitro was indirectly demonstrated. The possible role these inactivated compounds may play during the DSF-modulation of carcinogenesis will be discussed.

Disulfiram treatment was associated with significantly better retention in treatment, as well as longer duration of abstinence from alcohol and cocaine use. The two active psychotherapies (CBT and TSF) were associated with reduced cocaine use over time compared with supportive psychotherapy (CM). Cocaine and alcohol use were strongly related throughout treatment buy antabuse online , particularly for subjects treated with disulfiram.

n-Butyraldoxime (n-BO) is known to cause a disulfiram/ethanol-like reaction in humans, a manifestation of the inhibition of hepatic aldehyde dehydrogenase (AIDH). As with a number of other in vivo inhibitors of AIDH, n-BO does not inhibit purified AIDH in vitro, suggesting that a metabolite of n-BO is the actual inhibitor of this enzyme. In re-examination of the effect of n-BO on blood acetaldehyde levels following ethanol in the Sprague-Dawley rat, we found that pretreatment with substrates and/or inhibitors of cytochrome P450 blocked the n-BO-induced rise in blood acetaldehyde in the following order of decreasing potency: 1-benzylimidazole (0.1 mmol/kg) > 3-amino-1,2,4-triazole (1.0 g/kg) > ethanol ( buy antabuse online 3.0 g/kg) > phenobarbital (0.1% in the drinking water, 7 days) > SKF-525A (40 mg/kg). Rat liver microsomes were shown to catalyze the conversion of n-BO to an active metabolite that inhibited yeast AIDH. This reaction was dependent on NADPH and molecular oxygen and was inhibited by CO and 1-benzylimidazole. Hydroxylamine, postulated by others to be a metabolite of n-BO, inhibited AIDH via a catalase-mediated reaction and not through an NADPH-supported microsome-catalyzed reaction. Using GLC-mass spectrometry, 1-nitrobutane (an N-oxidation product) and butyronitrile (a dehydration product) were identified as metabolites from microsomal incubations of n-BO. However, neither of these metabolic products inhibited AIDH directly or in the presence of liver microsomes and NADPH. We conclude that another NADPH-dependent, cytochrome P450-catalyzed metabolic product of n-BO is responsible for the inhibition of AIDH by n-BO.

Rats were treated with either coprine or disulfiram and the inhibition of aldehyde dehydrogenase (ALDH) in liver and brain mitochondria was measured with acetaldehyde, 3,4-dihydroxyphenylacetaldehyde (DOPAL), and succinate semialdehyde at different concentrations. The inhibition pattern was similar for both inhibitors, but the degree of inhibition was lower with disulfiram. The ALDH activity both in the liver and the brain was inhibited at low concentrations of acetaldehyde and DOPAL, but not with succinate semialdehyde. The high-Km enzyme activities with acetaldehyde were not inhibited in liver and brain. The activity at high concentration of DOPAL was inhibited in the liver, but only slightly affected buy antabuse online in the brain, suggesting the presence of a brain enzyme with an intermediate Km value for DOPAL. In contrast with the results observed in vivo, it was found that the high-Km activities with acetaldehyde and DOPAL in brain mitochondrial preparations were more sensitive to the inhibitors in vitro than the low-Km activities. Kinetic studies on ALDH preparations from brain and liver mitochondria suggested that acetaldehyde and DOPAL are metabolized by the same low-Km ALDH.

Total halothane dose, measured by cumulative end-tidal (3.8 SE 0.1 minimum buy antabuse online alveolar concentration hours) and blood halothane concentrations, was similar in the two groups. Plasma concentrations and urinary excretion of trifluoroacetic acid and bromide, indicative of oxidative and total (oxidative and reductive) halothane metabolism, respectively, were significantly diminished in disulfiram-treated patients. In control and disulfiram-treated patients cumulative 96 h postoperative trifluoroacetic acid excretion was 12,900 (SE 1700) and 2010 (440) mumol, respectively (p < 0.001) while that of bromide was 1720 (290) and 160 (70) mumol (p < 0.001).

This study examines the effects of tetraethylthiuram disulfide (TTD; disulfiram, Antabuse) on the toxicokinetics in mice of 109Cd-labelled cadmium buy antabuse online chloride, as determined by whole-body and organ gamma-counting. At the highest single dose of orally administered CdCl2, i.e. 70 mumol/kg, orally administered TTD enhanced the inhibitory effect of CdCl2 on intestinal motility and increased the fractional whole-body retention of the dose of cadmium chloride, indicating enhanced intestinal cadmium absorption. Also, TTD induced extensive changes in organ distribution of absorbed cadmium; the relative hepatic and testicular deposition was reduced, while the relative deposition in heart, spleen, lungs, brain and carcass was increased. In a prolonged exposure experiment where CdCl2 was added to the drinking water and TTD to the feed, TTD increased the intestinal absorption of cadmium by more than four-fold as compared to the controls. Further, decreased deposition was seen in the carcass and increased deposition in intestines and liver. In a third experiment, oral doses of TTD given twice weekly had no influence on the rate of excretion of aged cadmium depots, and also the organ distribution was unchanged. Thus, the effect of TTD on cadmium metabolism seems to be exerted only during intestinal absorption and the distribution phase immediately thereafter.

We retrospectively evaluated the use of disulfiram among alcoholic patients being treated for active tuberculosis. There were 13 alcoholics treated with disulfiram, 105 alcoholics not on disulfiram, and 249 non-alcoholics. Rates of toxicity were higher among alcoholics than among non-alcoholics (58% vs. 32%), but there was no difference between alcoholics taking and those not taking disulfiram (61% vs. 57%). There were no neurological side Serevent Mdi Dosage effects in the disulfiram group. Disulfiram appeared to be safe when added to intermittent, directly observed isoniazid-containing tuberculosis treatment, and was useful in managing complications of alcohol abuse. However, the small number of patients on disulfiram limits the strength of this negative finding.

Aldehyde dehydrogenase (ALDH) enzymes are responsible for the metabolism of aldehydes, including acetaldehyde (AA), and are linked to disease. We describe a method to study ALDH activity in cell cultures involving the measurement of AA concentrations in the gas/vapour phase. This has been achieved using selected ion flow tube mass spectrometry (SIFT-MS), developed for the rapid quantification of trace gases in humid media. Human cells of the hepG2 hepatocellular carcinoma cell line and primary bone marrow-derived mesenchymal stem cells (hMSCs) depleted AA from the culture media, but the application of ALDH inhibitors diethylaminobenzaldehyde (DEAB) and disulfiram (DSF), suppressed this depletion or in some cases resulted in elevated AA concentrations. Further, the cells were shown to reduce the dimethyl sulphoxide (DMSO) to dimethyl sulphide, which is mediated by methionine sulfoxide reductase A (MsrA) enzymes. Interestingly, this process was also Celebrex Online inhibited by DEAB and DSF. The results of this study indicate that SIFT-MS gas phase analysis could be applied to the study of volatile metabolites of intracellular enzyme reactions, this having potential utility in disease research and drug discovery.

The steps that control the Entamoeba histolytica glycolytic flux were here identified by elasticity analysis, an experimental approach of metabolic control analysis. The concentrations of glycolytic metabolites were gradually varied in live trophozoites by (a) feeding with different glucose concentrations and (b) inhibiting the final pathway steps; in parallel, the changes in the pathway flux were determined. From the metabolite concentration-flux relationship, the elasticity coefficients of individual or groups of pathway reactions were determined and used to calculate their respective degrees of control on the glycolytic flux (flux control coefficients). The results indicated that the pathway flux was Symmetrel Tablets mainly controlled (72-86%) by the glucose transport/hexokinase/glycogen degradation group of reactions and by bifunctional aldehyde-alcohol dehydrogenase (ADHE; 18%). Further, inhibition of the first pathway reactions with 2-deoxyglucose (2DOG) decreased the glycolytic flux and ATP content by 75% and 50%, respectively. Cell viability was also decreased by 2DOG (25%) and more potently (50%) by 2DOG plus the ADHE inhibitor tetraethylthiuram disulfide (disulfiram). Biosate as an alternative carbon (amino acid) source was unable to replace glucose for ATP supply, which indicated that glucose was the main nutrient for amoebal ATP synthesis and survival. These results indicated that glycolysis in the parasite is mainly controlled by the initial pathway reactions and that their inhibition can decrease the parasite energy load and survival.

It was shown that the prevalence of alcoholism among pulmonary tuberculosis patients was high and the outcomes of both the diseases proceeding in the presence of lowered immunity were often unfavourable, including the results of long-term follow-ups. The use of a specially constructed instrument for investigating the neurodynamic characteristics of the cerebral cortex and determination of gamma-glutamyl transpeptidase in the serum promoted diagnosis of prenosological entities of alcoholism. Higher efficacy of alcoholism treatment in the patients with tuberculosis was achieved with narcotic psychotherapy using the mixture of nitrous oxide and oxygen, esperal implantation and application of rifusal, a new preparation, as well as application of extracorporeal hemosorption and enterosorption for eliminating the intoxication. Higher efficacy of tuberculosis treatment in the alcoholic patients was achieved with intravenous drop-wise infusion of antituberculous drugs along with other routes of administration. For increasing the cellular immunity, the patients were treated with chlorophylliptum or Effexor Maximum Dose T-activin. Continuation of the complex antialcoholic and antituberculous treatment of outpatients along with simultaneous observation by phthisiologists and narcologists provided higher results.

Disulfiram, an aldehyde dehydrogenase (ALDH) inhibitor, induces a flushing reaction upon the ingestion of ethanol, exerting aversion against alcohol that has been used in the treatment of alcoholism. This unpleasant response has been associated with an accumulation of acetaldehyde, and more recently, with an increase in vascular prostacyclin (PGI2) production. To evaluate the possibility of evoking the flushing reaction with drugs less toxic than disulfiram, we studied the effects of propranolol and dipyridamole on ALDH and PGI2. Acetaldehyde oxidation rate was assessed by gas chromatography in mitochondria from rats treated with these drugs for seven days. Prostacyclin generation was determined in rat aortic rings incubated in Krebs-Ringer with these drugs separately and associated to acetaldehyde, and measured by radioimmunoassay of 6-keto-PGF1 alpha. Propranolol inhibited acetaldehyde oxidation rate whereas dipyridamole did not. Furthermore, propranolol increased blood acetaldehyde levels without affecting ethanol elimination rate. Both drugs stimulated prostacyclin synthesis but only dipyridamole enhanced the stimulatory effect of acetaldehyde on vascular prostacyclin production. These results strongly suggest the possibility of producing a deterrent effect on the consumption of alcohol by using propranolol or dipyridamole. In contrast to disulfiram, these drugs could potentially induce the flushing reaction in humans in the presence of low acetaldehyde Asacol Tablets 800mg concentrations; this new therapeutic approach might have an important clinical and toxicological relevance.

Associated with the oxazaphosphorine-specific acquired resistance exhibited by a human breast adenocarcinoma subline growing in monolayer culture, viz. MCF-7/OAP, was the overexpression (> 100-fold as compared with the very small amount expressed in the oxazaphosphorine-sensitive parent line) of a class 3 aldehyde dehydrogenase, viz. ALDH-3, judged to be so because it is a polymorphic enzyme (pI values ca. 6.0) present in the cytosol that is heat labile, is insensitive to inhibition by disulfiram (25 microM), much prefers benzaldehyde to acetaldehyde as a substrate and, at concentrations of 4 mM, prefers NADP to NAD as a cofactor. No other aldehyde dehydrogenases were found in these cells. As compared with those of the prototypical class 3 human ALDH-3, viz. constitutive human stomach mucosa ALDH-3, the physical and catalytic properties of the MCF-7/OAP enzyme differed somewhat with regard to pI values, native M(r), subunit M(r), recognition of the subunit by anti-stomach ALDH-3 IgY, pH stability, cofactor influence on catalytic activity, and the ability to catalyze, albeit poorly, the oxidation of an oxazaphosphorine, viz. aldophosphamide. Hence, the MCF-7/OAP ALDH-3 was judged to be a novel class 3 aldehyde dehydrogenase. Small amounts of a seemingly identical enzyme are also present in normal pre- and post-menopausal breast tissue. None could be detected in human liver, kidney or placenta, suggesting that it may be a tissue-specific enzyme.

The proteasome pathway is an important target for anticancer drug development. Here, we identify the antialcoholism drug disulfiram and its analogue pyrrolidine dithiocarbamate (PDTC) as inhibitors of the 26S proteasome activity in a cell-based screening assay. As expected for proteasome inhibitors, these compounds also inhibited TNF-alpha-induced nuclear factor-KappaB (NF-KappaB) translocation and were cytotoxic. Disulfiram was more cytotoxic against chronic lymphocytic leukemia cells compared to peripheral blood mononuclear cells (PBMC) at clinically achievable concentrations. Proteasome and NF-KappaB inhibition were achieved with a potency in the same range as that of the clinically used proteasome inhibitor bortezomib. Disulfiram was also able to induce accumulation of p27(Kip1) and to prolong the half-life of c-Myc, both targets for proteasome-dependent degradation. It is concluded that the previously observed antitumoral and NF-KappaB inhibiting activity of disulfiram and PDTC could be attributed to their inhibition of the 26S proteasome.

Suffering from alcohol dependence, as well as realizing the need for, and entering treatment, were associated with shame and stigma, and were strong barriers to treatment. Other barriers included the desire to deal with alcohol problems on one's own and the view that seeking treatment required total abstinence. Negative health-effects were mainly a nonissue. The participants' knowledge about treatment options was limited to lifelong abstinence, medication with Disulfiram and residential treatment. These were seen as unappealing and contrasted sharply with preferred treatment. CONCLUSIONS/IMPORTANCE: Public health literacy regarding alcohol use, dependence, and treatment ought to be improved in order to lower barriers to treatment. Treatment services need to better match the needs and wishes of potential service users, as well as taking stigmatization into account. In order to develop suitable treatments, and to reach the majority who do not seek treatment, the clinical understanding of alcohol dependence needs to be expanded to include mild to moderate dependence.

Phosphatidylserine (PS) exposure on the surface of cells has been considered a characteristic feature of apoptosis. However, we demonstrate herein that externalization of PS occurs in a cell-type-specific, albeit caspase-dependent, manner. Moreover, we could find no correlation in six different cell lines between the level of expression of the phospholipid (PL) scramblase and the capacity of these cells to externalize PS during apoptosis. Overexpression of PL scramblase in Raji cells, which exhibit low constitutive expression of this enzyme, by retroviral transduction of PL scramblase or treatment of the cells with interferon-alpha, failed to confer the capacity to expose PS in response to apoptotic stimuli. However, the lack of PS exposure in some cell types was not due to their inability to translocate PS molecules to the cell surface, since incubation with thiol reactive agents, such as N-ethylmaleimide, disulfiram and diamide, yielded rapid and pronounced PS exposure in all cell lines. These data suggest that plasma membrane PS exposure is not an obligatory component of the apoptotic phenotype, and that PL scramblase is not the sole determinant of PS externalization in apoptotic cells when this occurs.
