Active clinical trials for "Substance Withdrawal Syndrome"

We hypothesize that transcranial direct current stimulation will reduce tobacco withdrawal symptoms of tobacco dependent smokers abstinent from smoking for more than 10 hours.

The purpose of this study is to determine the timeframe (relative to a stress task) that is most effective at attenuating the increase in symptoms of tobacco craving and withdrawal that occur when smokers are presented with stressful situations.

The purpose of RESC study is to assess the efficacy of Energetic Resonance by Cutaneous Stimulation on alcohol withdrawal symptoms measured by CUSHMAN score and in a second time to measure the benzodiazepine amount prescribed during the withdrawal time.

Objectives: To evaluate neural correlates associated with emotional processing during nicotine withdrawal preferentially involving the amygdala and associated areas within the corticolimbic and mesolimbic circuitry. We hypothesize that relative to a pre-quit baseline, post-quit nicotine withdrawal will result in increased activity to negative emotional cues, in contrast to other cues, in one or more areas of interest, and particularly in the right cerebral hemisphere. To determine if bupropion and varenicline moderate patterns of brain activation during post-quit nicotine withdrawal. We hypothesize that relative to placebo, bupropion and varenicline will attenuate the effects of post-quit nicotine withdrawal on emotional processing, reducing activation to negative emotional cues, relative to other cues, in one or more areas of interest, and particularly in the right cerebral hemisphere. To determine if genotype (DRD2 TaqA2 allele and the ins variant of the -141C ins/del DRD2) moderates patterns of brain activation during post-quit nicotine withdrawal.

Quitting smoking is a big decision, a decision to achieve better health. Trying to quit smoking can be stressful. The prospect of dealing with withdrawal symptoms, fear or failure to change the routine, can also be sources of stress. Withdrawal from nicotine is characterized by symptoms that include anxiety, irritability, hunger and cravings for more tobacco. Nicotine creates a dependency so that the body develops a need for a certain level of nicotine at all times. Unless that level is maintained symptoms of withdrawal appear. For tobacco users trying to quit, symptoms of withdrawal from nicotine are unpleasant and stressful, but they are temporary. Research has demonstrated the relative effectiveness of pharmacotherapy treatments in smoking cessation but no studies have examined the effects of the probiotics on the withdrawal symptoms associated with the tobacco cessation during nicotine replacement therapy (NRT). The purpose of this study is to assess the effectiveness of two probiotic products during NRT for managing withdrawal symptoms associated with smoking cessation.

This single-center study is a randomized, double-blind, active-controlled, multiple-dose, parallel group study to evaluate the potential withdrawal effects, safety and tolerability, and pharmacokinetic and pharmacodynamic effects of multiple doses of oral intact Oxycodone/Naltrexone capsules compared to oxycodone in methadone-maintained opioid-dependent subjects. The study will consist of a Screening Phase, an inpatient Treatment Phase (including a methadone stabilization period, a placebo administration period, a treatment administration period and a safety/washout period), and a Follow-up Phase.

Study rationale: Sensory/behavioural elements of smoking play a role in smoking behaviour and may have a potential to assist smoking cessation. Among current treatments for smokers, only the nicotine inhalator is attempting to address such factors. The inhalator's efficacy does not exceed that of the other nicotine replacement therapy (NRT) products, but it mimics the relevant sensory input to only a limited extent, and its nicotine delivery is dependent on intensive puffing. Recently a new product, the Electronic Cigarette (E-C) has become available, which provides a more realistic behaviour and sensory replacement for smoking and can provide good nicotine levels with less effort. Primary objective: To compare E-C and nicotine inhalator in their effects on tobacco withdrawal symptoms over 24hr abstinence. Hypotheses: E-C will be more effective than the inhalator in reducing withdrawal symptoms and craving and elicit more favorable user ratings. It will also provide higher nicotine levels. Study design: In a cross-over study, participants will be randomized to the sequence of conditions and provide baseline measures and samples for salivary cotinine analysis. They will be asked to abstain from smoking their usual cigarettes and use the allocated product over 24 hours. They will return to the study centre the following day, and complete measures of craving and withdrawal, ratings of subjective and sensory effects of the products, product satisfaction, and adverse effects. They will also provide saliva samples for cotinine analysis. Abstinence from smoking will be verified with CO readings.

A 30 alcohol dependent patients were divided into A: Treatment group and B: Placebo group using simple randomization technique. (Liver function tests) GGT, ALT and AST levels and MCV (Mean corpuscular volume) at admission and 2 weeks later were estimated. Daily withdrawal symptoms were assessed using the Clinical Institute Withdrawal Assessment scale (CIWA-Ar) and DTs by Delirium Observation Screening (DOS) Scale (version 0 - 1). The data collected from the two groups were compared.

Severe acute alcohol withdrawal syndrome is a potentially life-threatening condition characterized by agitation, confusion, abnormal heart rhythms and seizures. Typically, clinicians treat the symptoms of alcohol withdrawal with a class of medications known as benzodiazepines (e.g., Valium). These medications have a short duration of activity and require repeated administration, often every hour or less, to reduce the symptoms of alcohol withdrawal. Many patients suffer complications related to inadequate treatment of alcohol withdrawal (e.g., abnormal heart rhythms, aspiration, seizures) resulting in admission to an intensive care unit and prolonged hospital stay, all of which increase healthcare costs. Although alcohol withdrawal is common, especially among disadvantaged (e.g., homeless) patients, limited funding is available to advance the care of patients suffering from alcohol withdrawal. A safe and effective treatment for severe alcohol withdrawal would benefit patients and our healthcare system. Phenobarbital is an inexpensive, commonly available medication that is typically used to treat seizures. A key advantage of phenobarbital is that its calming effect lasts for a long period of time and it can be given as a 'one-time-dose' intravenously, so that it both prevents and treats withdrawal symptoms and reduces the need for repeated benzodiazepines. Through better symptom control, phenobarbital is expected to reduce the costs and complications of alcohol withdrawal. At present, physicians rarely use phenobarbital for this purpose, and additional research is needed for this medication to become part of routine care in clinical practice. The PHENOMANAL pilot trial will assess safety and whether clinicians can administer a single dose of phenobarbital intravenously, in addition to benzodiazepines, compared to benzodiazepines alone for treating patients with severe alcohol withdrawal. This information will inform the design of a larger clinical trial. For patients, the PHENOMANAL trial has the potential to revolutionize how patients suffering from severe alcohol withdrawal are treated. For society and the healthcare system, phenobarbital is expected to reduce the complications and costs associated with severe alcohol withdrawal.

Summary: There have been two published RCTs showing efficacy of buprenorphine treatment for NAS. However these trials excluded an estimated 22-47% of infants requiring pharmacologic treatment; those infants born to mothers with co-dependence on an opiate and a benzodiazepine. Although there are concerns, we anticipate that buprenorphine will be safe in this population. If it is safe, we can include these infants in the large double blind, double-dummy buprenorphine and clonidine vs. morphine and clonidine trial. If on the other hand, these infants have respiratory depression or other adverse events when buprenorphine is given, it will be important to report this study and caution the use of buprenorphine in these infants
