  • Background to the Celebration of Herbert D. Kleber (1904 -2018) by Thomas A
    1 Background to the Celebration of Herbert D. Kleber (1904 -2018) by Thomas A. Ban By the mid-1990s the pioneering generation in neuropsychopharmacology was fading away. To preserve their legacy the late Oakley Ray (1931-2007), at the time Secretary of the American College of Neuropsychopharmacology (ACNP), generated funds from Solway Pharmaceuticals for the founding of the ACNP-Solway Archives in Neuropsychopharmacology. Ray also arranged for the videotaping of interviews (mainly by their peers) with the pioneers, mostly at annual meetings, to be stored in the archives. Herbert Kleber was interviewed by Andrea Tone, a medical historian at the Annual Meeting of the College held in San Juan, Puerto Rico, on December 7, 2003 (Ban 2011a; Kleber 2011a). The endeavor that was to become known as the “oral history project” is based on 235 videotaped interviews conducted by 66 interviewers with 213 interviewees which, on the basis of their content, were divided and edited into a 10-volume series produced by Thomas A. Ban, in collaboration with nine colleagues who were to become volume editors. One of them, Herbert Kleber, was responsible for the editing of Volume Six, dedicated to Addiction (Kleber 2011b). The series was published by the ACNP with the title “An Oral History of Neuropsychopharmacology Peer Interviews The First Fifty Years” and released at the 50th Anniversary Meeting of the College in 2011 (Ban 2011b). Herbert Daniel Kleber was born January 19, 1934, in Pittsburgh, Pennsylvania. His family’s father’s side was from Vilnius, Lithuania, and the Mother’s side was from Germany. Both families came to the United State during the first decade of the 20th century.

  • Advances in Opioid Antagonist Treatment for Opioid Addiction
    Advances in Opioid Antagonist Treatment for Opioid Addiction a, a b Walter Ling, MD *, Larissa Mooney, MD , Li-Tzy Wu, ScD KEYWORDS • Addiction treatment • Depot naltrexone • Opioid dependence • Relapse KEY POINTS • The major problem with oral naltrexone is noncompliance. Administration of naltrexone as an intramuscular injection may be less onerous and improve compliance because it occurs only once a month (ie, extended-release depot naltrexone). • To initiate treatment with extended-release depot naltrexone, steps should be taken to ensure that the patient is sufficiently free from physical dependence on opioids (eg, detoxification). • Research on naltrexone in combination with other medications suggests many opportu- nities for studying mixed receptor activities in the treatment of opioid and other drug addictions. PERSPECTIVE ON OPIOID ANTAGONIST TREATMENT FOR ADDICTION Naltrexone, an opioid antagonist derived from the analgesic oxymorphone, was synthesized as EN-1639A by Blumberg and colleagues in 1967. Four years later, in 1971, naltrexone was selected for high-priority development as a treatment for opioid addiction by the Special Action Office for Drug Abuse Prevention, an office created by President Nixon and put under the leadership of Dr Jerome Jaffe. Extinction Model The rationale for the antagonist approach to treating opioid addiction had been advanced by Dr Abraham Wikler a decade earlier, based largely on the extinction model explored in animal behavioral studies. It was believed that by blocking the euphorogenic effects of opioids at the opioid receptors, opiate use would become Disclosures: Dr Ling has served as a consultant to Reckitt Benckiser Pharmaceuticals and to Alkermes, Inc.

  • Novel Algorithms for the Prophylaxis and Management of Alcohol Withdrawal Syndromes–Beyond Benzodiazepines
    Novel Algorithms for the Prophylaxis and Management of Alcohol Withdrawal Syndromes–Beyond Benzodiazepines José R. Maldonado, MD KEYWORDS Alcohol withdrawal Withdrawal prophylaxis Benzodiazepines Anticonvulsant agents Alpha-2 agonists Delirium tremens KEY POINTS Ethanol affects multiple cellular targets and neural networks; and abrupt cessation results in generalized brain hyper excitability, due to unchecked excitation and impaired inhibition. In medically ill, hospitalized subjects, most AWS cases (80%) are relatively mild and un- complicated, requiring only symptomatic management. The incidence of complicated AWS among patients admitted to medical or critical care units, severe enough to require pharmacologic treatment, is between 5% and 20%. Despite their proven usefulness in the management of complicated AWS, the use of BZDP is fraught with potential complications. A systematic literature review revealed that there are pharmacologic alternatives, which are safe and effective in the management of all phases of complicated AWS. BACKGROUND Alcohol use disorders (AUDs) are maladaptive patterns of alcohol consumption mani- fested by symptoms leading to clinically significant impairment or distress.1 Ethanol is the second most commonly abused psychoactive substance (second to caffeine) and AUD is the most serious drug abuse problem in the United States2 and worldwide.3 The lifetime prevalences of Diagnostic and Statistical Manual of Mental Disorders,4thedi- tion, alcohol abuse and dependence were 17.8% and 12.5%, respectively; the total life- time prevalence for any AUD was 30.3%.4 Alcohol consumption-related problems are the Psychosomatic Medicine Service, Emergency Psychiatry Service, Department of Psychiatry and Behavioral Sciences, Stanford University School of Medicine, 401 Quarry Road, Suite 2317, Stan- ford, CA 94305-5718, USA E-mail address: [email protected] Crit Care Clin 33 (2017) 559–599 http://dx.doi.org/10.1016/j.ccc.2017.03.012 criticalcare.theclinics.com 0749-0704/17/ª 2017 Elsevier Inc.
