CONTEXT Clinicians have traditionally withheld opiate analgesia from patients with acute abdominal pain until after evaluation by a surgeon, out of concern that analgesia may alter the physical findings and interfere with diagnosis. OBJECTIVE To determine the impact of opiate analgesics on the rational clinical examination and operative decision for patients with acute abdominal pain. DATA ...
Scientific information about the neurobiology of addictive behaviors provides an increasingly important rationale to support opioid agonist pharmacotherapy, primarily methadone maintenance treatment, for long-term heroin addiction. In late 1963 and 1964, the first research was performed at The Rockefeller Institute for Medical Research by Dole, Nyswander, and Kreek in an attempt to develop a ne...
Several medications are approved for treatment of opiate abuse, but determinants of their clinical effectiveness are not completely understood. States of opiate dependence or withdrawal may constitute one important set of determinants. To test this hypothesis, the effects of naloxone, buprenorphine, and methadone were assessed on choice between heroin and food in nondependent rhesus monkeys and...
The importance of the GABA-benzodiazepine receptor complex and its subtypes are increasingly recognised in addiction. Using the α1/α5 benzodiazepine receptor PET radioligand [(11)C]Ro15 4513, we previously showed reduced binding in the nucleus accumbens and hippocampus in abstinent alcohol dependence. We proposed that reduced [(11)C]Ro15 4513 binding in the nucleus accumbens was a marker of add...
BACKGROUND Ketamine is an N-methyl-d-aspartate receptor antagonist that has been shown to be useful in the reduction of acute postoperative pain and analgesic consumption in a variety of surgical interventions with variable routes of administration. Little is known regarding its efficacy in opiate-dependent patients with a history of chronic pain. We hypothesized that ketamine would reduce post...
