We hypothesized that the opioid antagonist naltrexone would inhibit the redevelopment of a preference for a high-sucrose diet after an abstention period from this diet. Rats that chose between a starch or sucrose diet for 10 days preferred the sucrose diet. Rats were then given access to the starch diet alone for another 10-day period. A miniosmotic pump containing saline or naltrexone was then...
PURPOSE Obese individuals vary in their experience of food cravings and tendency to engage in reward-driven eating, both of which can be modulated by the neural reward system rather than physiological hunger. We examined two predictions in a sample of obese women: (1) whether opioidergic blockade reduced food-craving intensity, and (2) whether opioidergic blockade reduced an association between...
There is a concerted research effort to investigate brain mechanisms underlying addiction processes that may predicate the development of new compounds for treating addiction. One target is the brain's opioid system, because of its role in the reinforcing effects of substances of abuse. Substance-dependent populations have increased numbers of the mu opioid receptor (MOR) in fronto-striatal reg...
Objectives: To investigate the hypothesis that naltrexone augmentation of antipsychotics may show beneficial effects on symptoms of schizophrenia. Method: Sixty nine participants were randomized to two groups for a 12-weeks trial. Positive and negative symptoms of schizophrenia were assessed with the Scale for Assessment of Positive Symptoms (SAPS) and the Scale for Assessment of Negative Sympt...
Gambling is characterized by cognitive distortions in the processing of chance and skill that are exacerbated in pathological gambling. Opioid and dopamine dysregulation is implicated in pathological gambling, but it is unclear whether these neurotransmitters modulate gambling distortions. The objective of the current study was to assess the effects of the opioid receptor antagonist naltrexone ...
S. HERLING, Naltrexone effects on foodand codeine-maintained responding in rhesus monkeys, European J. Pharmacol. 73 (1981) 41--49. The delivery of food or the i.v. injection of codeine maintained lever pressing in rhesus monkeys during alternating periods of daily experimental sessions. Responding was maintained by food or codeine under a chain differential reinforcement of other behavior 30 s...
AbstractObjectives: The purpose of present study was to review the literature for advantages and shortcomings of ultra rapid detoxification. This method often is performed with naloxone and naltrexone with symptoms of withdrawal controlled under general anesthesia or deep sleep. Method: More than 70 full text articles were studied they were looked up in Medline, from 1985 to 2002, using the key...
AbstractObjectives: This project was conducted to compare two programs of treatment, the rapid (naltrexone/ clonidine) and the conventional (clonidine) detoxification. Method: 54 opioid dependent patients referred to the clinic of Iran Educational Psychiatric Center participated in the study they were randomly placed in two groups. 28 patients in group A (naltrexone/ clonidine) and 26 patients ...
This research study investigated the effect of nicotine gum, clonidine, and naltrexone, in the maintenance treatment of cigarette smoking. In a double blind study, 171 nicotine-dependent male subjects who met DSM-IV criteria for nicotine dependence and smoking 10 cigarettes or more per day, were allocated randomly to three equal groups of 57. Subjects received nicotine gum, clonidine, or naltre...
BACKGROUND There is increasing interest in naltrexone, an opiate antagonist, in the treatment of opiate addicts. The effects of naltrexone are often compromised by a lack of compliance and drop-out. The effects of this compound are probably more favorable when combined with a psychosocial intervention such as the Community Reinforcement Approach (CRA). AIM To explore the effects of a combinat...
