Opiate overdose produces pinpoint pupils and varying degrees of respiratory depression and impairment of consciousness. If there is coma or bradypnoea, the opiate antagonist naloxone should be given intravenously. If the patient has taken a long-acting opioid such as methadone, a naloxone infusion should be considered1. After the administration of naloxone, opiate-dependent patients will experi...

We compared the prevalence of prescription opiate misuse among 2 cohorts of felony probationers (N = 1525). Multiple logistic regression was utilized to determine the independent correlates of prescription opiate misuse among rural (n = 782) and urban (n = 743) probationers participating in an HIV-intervention study. After adjustment for differences in demographic and drug use characteristics, ...

Opiate, muscarinic, and alpha 2-adrenergic receptors and the Ni-coupled response of adenylate cyclase (AC) inhibition were examined in neuroblastoma X glioma NG108-15 (108 CC15) and neuroblastoma X Chinese hamster brain NCB-20 clonal hybrid cells, induced to differentiate with 1.0 mM dibutyryl cAMP (dBcAMP). Scatchard analysis of binding of the opiate agonist 3H-(D-Ala2,D-Leu5)enkephalin (DADLE...

BACKGROUND Partly because of a lack of a conventional, effective treatment for cocaine addiction, auricular acupuncture is used to treat this disorder in numerous drug treatment facilities across the country for both primary cocaine-dependent and opiate-dependent populations. OBJECTIVE To evaluate the effectiveness of auricular acupuncture for the treatment of cocaine addiction. METHODS Eig...

Crit Care Med 2016 • Volume 44 • Number 12 (Suppl.) 81 adult patients admitted to the ICU of a Level I trauma center for ≥48 hours. Subjects were screened for posttraumatic stress symptoms during hospitalization, and 3, 6, and 12 months later. BU was converted to lorazepam equivalents and dosage subgroups were created. Patient characteristics were compared using t-tests, Wilcoxon rank sum tests...

Extracellular and intracellular microelectrode studies were conducted to test the actions and interactions of naloxone and naltrexone, two supposedly "pure" opiate antagonists. Both were shown to depress excitability and action potential production when applied in relatively high concentrations. Low naltrexone concentrations antagonized the depression produced by naloxone, but low naloxone conc...

A simple, inexpensive dual-detector system has been developed for measurement of positronemitting receptor-binding drugs in the human brain. This high efficiency coincidence counting system requires that only a few hundred microcuries of labeled drug be administered to the subject, thereby allowing for multiple studies without an excessive radiation dose. Measurement of the binding of [11C]carf...

Naltrexone implants and depot injections (NI) are a novel form of treatment for opiate dependence (OD). Major questions relate to their absolute and relative efficacy and safety. Opportunely, six recent clinical trial data from several continents have uniformly provided dramatic evidence of the potent, dose-related and highly significant efficacy of NI, with minimal or manageable accompanying t...

Opiates have been implicated in learned helplessness (LH), a phenomenon known to be related to opiate stress-induced analgesia (SIA). In the present study, we investigated the role of opiates in the induction of LH and SIA under different conditions. Adult female Wistar rats were trained either by receiving 60 inescapable 1-mA footshocks (IS group, N = 114) or by confinement in the shock box (c...
