Difference of the naltrexone's effects in social drinkers by spicy food preference.
The purpose of this study was to investigate the differences in subjective acute effects of alcohol and naltrexone among those who prefer spicy food to varying degrees. Acute biphasic alcohol effects scale (BAES), visual analogue scale for craving (VAS-C), blood alcohol concentration (BAC) and food preference scale were measured in 26 men. Repeated measures ANOVA (2 preference groups×4 time blocks) on the stimulative subscale of BAES revealed a significant group by block interaction in naltrexone condition (N+) (P<0.001), but not in non-naltrexone condition (N-). ⋯ The paired t-test revealed that significant suppression of the stimulative subscale of BAES was observed at 15 min (P<0.001) and 30 min (P<0.001) after drinking when N+ compared with N- in SP. For those who prefer spicy food, the stimulative effect of acute alcohol administration was suppressed by naltrexone. This result suggests that the effect of naltrexone may vary according to spicy food preference.

Deaths related to opioid overdose have increased in the past decade. Community-based pharmacy practitioners have worked toward overcoming logistic and cultural barriers to make naloxone distribution for overdose prevention a standard and accepted practice. ⋯ Outpatient administration of intramuscular and intranasal naloxone represents a means of preventing opioid-related deaths. Pharmacists can play a vital role in contacting providers, provision of products, education of patients and providers, and dissemination of information throughout the community. Preventing opioid overdose-related deaths should become a major focus of the pharmacy profession.

Stress is related to heavy alcohol use and relapse in alcoholics. Using the reinstatement model, we have shown that corticotropin-releasing factor (CRF) underlies stress-induced relapse to alcohol seeking in laboratory rodents. Little is known about how other neurotransmitters interact with CRF in these effects. Dynorphin and its receptor (kappa opioid receptor, KOR) are involved in stress responses and in alcohol seeking. KOR and CRF receptors (CRF R) may interact in the production of stress-related behaviors but it is not known whether this interaction is involved in reinstatement of alcohol seeking. ⋯ These data further support a role for KOR in reinstatement of alcohol seeking under nonstress and stressful conditions and that KOR and CRF R interact in these effects.

Review Meta AnalysisDetoxification treatments for opiate dependent adolescents.
The scientific literature examining effective treatments for opioid dependent adults clearly indicates that pharmacotherapy is a necessary and acceptable component of effective treatments for opioid dependence. Nevertheless, no studies have been published that systematically assess the effectiveness of the pharmacological detoxification among adolescents. ⋯ It is difficult to draw conclusions on the basis of two trials with few participants. Furthermore, the two studies included did not consider the efficacy of methadone that is still the most frequent drug utilised for the treatment of opioid withdrawal. One possible reason for the lack of evidence could be the difficulty in conducting trials with young people due to practical and ethical reasons.
