Filter by:The purpose of the study is to determine whether buprenorphine is a beneficial, safe, cost effective treatment alternative to morphine sulfate in the treatment of Neonatal Abstinence Syndrome (NAS).
The overarching goal of this project is to improve the clinical quality of patients with Benzodiazepine-resistant alcohol withdrawal syndrome.
The primary objective of this study is to assess QTc (an interval of the heart rhythm) interaction effects between lofexidine and methadone. The secondary objectives of the study are to evaluate the safety and tolerability of lofexidine by evaluating and monitoring pharmacokinetics (amounts of drug in the blood), vital signs (heart rate and blood pressure) and adverse events (side effects) when co-administered with methadone; to describe effects on opiate withdrawal when lofexidine is introduced following a 50% methadone dose reduction, as required to elicit a withdrawal response; and to evaluate the QTc interaction effects of lofexidine compared with placebo. The investigators hypothesize that while both agents (lofexidine and methadone) are known to prolong the QTc interval, the combination of the drugs will not create an additive effect which creates a significant safety concern. The investigators further hypothesize that subjects will be able to tolerate the therapeutic dose of lofexidine (0.8 mg four times daily) when the methadone maintenance dose is lowered to elicit withdrawal.
Although there are several tools that can be used to evaluate the severity of ongoing alcohol withdrawal syndrome (AWS), there is no available tool that can predict which patients are at risk for developing AWS at the time admission, before the patient has developed AWS. Unfortunately, there are severe symptoms of alcohol withdrawal (e.g., seizures) which may develop early in the hospitalization, and before the development of other systemic symptoms which may warn medical personnel of the possibility of impeding alcohol withdrawal (e.g., autonomic instability, delirium). The goal of this study is to evaluate the psychometric properties (e.g., predictive validity) of a new tool, the Prediction of Alcohol Withdrawal Severity Scale (PAWSS), on identifying which patients are at risk for developing complicated AWS (i.e., seizures, hallucinosis, delirium tremens) among hospitalized, medically ill patients.
Background: - Marijuana is the most widely used illicit drug in the world, yet relatively little is known about users who try to quit without formal treatment ( spontaneous quitting). Studies have suggested that there are some common strategies that many individuals use in spontaneous quitting, such as changing one s lifestyle or identity, reminding oneself of negative consequences, support from family and friends, and religion. However, more research is needed to determine potential treatment strategies for marijuana use. Objectives: - To identify strategies used to help with marijuana quitting among non-treatment seeking adult marijuana users. - To identify withdrawal symptoms experienced during marijuana quitting and their relationship to the quitting strategies used and the outcome of the quit attempt. - To evaluate whether subgroups of marijuana users differ in their experience of marijuana quitting. Eligibility: - Individuals at least 18 years of age who have made at least one attempt to quit marijuana use. Design: - The study will consist of one visit of approximately 1 to 2 hours. - Participants will fill out three questionnaires. The questionnaires have different types of questions, and will ask about background and lifestyle, marijuana use and craving patterns and behaviors, and difficulties in previous attempts to quit using marijuana.
The primary objective of this study is to assess QTc (an interval of the heart rhythm) interaction effects between lofexidine and methadone. The secondary objectives of the study are to evaluate the safety and tolerability of lofexidine by evaluating and monitoring pharmacokinetics (amounts of drug in the blood), vital signs (heart rate and blood pressure) and adverse events (side effects) when co-administered with methadone; and to describe effects on opiate withdrawal when lofexidine is introduced following a 50% or 100% methadone dose reduction, as required to elicit a withdrawal response. The investigators hypothesize that while both agents are known to prolong the QTc interval, the combination of the drugs will not create an additive effect which creates a significant safety concern. The investigators further hypothesize that subjects will be able to tolerate the therapeutic dose of lofexidine (0.8 mg four times daily) when the methadone maintenance dose is lowered to elicit withdrawal.
Opioid medications are commonly used for pain relief. When given over time, physical dependence can occur. This results in unpleasant side effects (such as agitation and nausea) if opioid medications are suddenly stopped. This study aims to test the use of the drug ondansetron to reduce the symptoms associated with opioid withdrawal and to prevent the progression of opioid physical dependence, thereby allowing future investigators to better test the role of physical dependence in the development of addiction and also possibly improving acceptance of abstinence-based programs for addiction.
A polymorphism in the dopamine transporter (DAT) may determine how much dopamine is available at the synapse and this may affect the underlying reasons for relapse in smokers. This research will use Single-photon emission computed tomography SPECT and the DAT-specific ligand, TRODAT (Dopamine Transporter Density by [99mTc]), to examine the availability of DAT in smokers grouped by genotype in the sated (just having smoked) and withdrawal (4 hours without smoking) conditions.
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.
This will be a 2-4 week double-blind, placebo-controlled study. Twenty four male and female smokers will first have two 4-day treatment periods, in which they will be randomized to galantamine (8 mg/day) or placebo. These treatment periods will be separated by a 3 to 14 day washout period. During the first 3-days of each treatment period, smokers will have daily clinic visits, where they will receive study medications and any adverse effects from study medications will be monitored. Starting at 10 p.m. on Day 1 of each treatment period, subjects will refrain from smoking for approximately 2.5 days, until the experimental session on Day 4. Compliance with non-smoking will be verified by CO levels < 10 ppm. During the experimental sessions, subjects will receive saline or 1.0 mg/70 kg of nicotine intravenously in a random, double-blind manner. The sequence of nicotine treatments will be counterbalanced among subjects such that equal number of subjects will receive saline first or nicotine first. Following each saline and nicotine treatments, physiological, subjective and cognitive measurements will be obtained
