Pande1, Brian J. Piper1,2* 1Department of Medical Education, Geisinger Commonwealth School of Medicine 2Center for Pharmacy Innovation and Outcomes * Brian J. Piper, Ph.D.525 Pine Street, Geisinger Commonwealth School of Medicine Scranton, PA 18411, USA Abstract: Buprenorphine, an analogue of thebaine, is a Schedule III opioid in the United States used for opioid-use disorder and as an analgesic. Research has shown drugs like buprenorphine have a complicated pharmacology with characteristics that challenge traditional definitions of terms like agonist, antagonist, and efficacy. Buprenorphine has a high affinity for the mu (MOR), delta (DOR), kappa (KOR), and intermediate for the nociceptin opioid receptors (NOR). Buprenorphine is generally described as a partial MOR agonist with limited activity and decreased response at the mu- receptor relative to full agonists. In opioid naïve patients, the drug’s analgesic efficacy is equivalent to a full MOR agonist, despite decreased receptor occupancy and the “ceiling effect” produced from larger doses. Some argue buprenorphine’s effects depend on the endpoint measured, as it functions as a partial agonist for respiratory depression, but a full-agonist for pain. Buprenorphine’s active metabolite, norbuprenorphine, attenuates buprenorphine's analgesic effects due to NOR binding and respiratory depressant effects. The method of administration impacts efficacy and tolerance when administered for analgesia. There have been eleven-thousand reports involving buprenorphine and minors (age < 19) to US poison control centers, the preponderance (89.2%) with children. -

Litjens RPW, Brunt TM. Clin Toxicol 2016; online early: doi: 10.3109/15563650.2016.1138226: Context Ibogaine is a psychoactive indole alkaloid found in the African rainforest shrub Tabernanthe Iboga. It is unlicensed but used in the treatment of drug and alcohol addiction. However, reports of ibogaine's toxicity are cause for concern. Objectives To review ibogaine's pharmacokinetics and pharmacodynamics, mechanisms of action and reported toxicity. Methods A search of the literature available on PubMed was done, using the keywords "ibogaine" and "noribogaine". The search criteria were "mechanism of action", "pharmacokinetics", "pharmacodynamics", "neurotransmitters", "toxicology", "toxicity", "cardiac", "neurotoxic", "human data", "animal data", "addiction", "anti-addictive", "withdrawal", "death" and "fatalities". The searches identified 382 unique references, of which 156 involved human data. Further research revealed 14 detailed toxicological case reports.

Use of Analgesics in Exotic Felids Edward C. Ramsay, DVM Professor, Department of Small Animal Clinical Sciences, University Of
Use of Analgesics in Exotic Felids Formatted: Centered Edward C. Ramsay, DVM Professor, Department of Small Animal Clinical Sciences, University of Tennessee, and Consulting Veterinarian, Knoxville Zoological Gardens, Knoxville, Tennessee. Corresponding address: Ed Ramsay Dept. of Sm Animal Clin Sci C247, Veterinary Teaching Hospital University of Tennessee Knoxville, TN 37996-4544 Phone: 865-755-8219 FAX: 865-974-5554 Email: [email protected] 2 Treatment of pain in domestic and non-domestic cats has been a challenge for the clinician. Many cat species are stoic and show few or very subtle external signs of pain. Additionally, the adverse effects of nonsteroidal antiinflammatory drugs (NSAIDs) in domestic cats are well documented and have discouraged many practitioners from trying novel NSAID’s in exotic felids. As in other animals, each cat’s response to pain and analgesics will vary, necessitating an individualized treatment plan. As a rule, always treat painful felids to effect, and not by rote reliance on published dosages. It is frequently necessary to try different agents and combinations to find which produces the optimal analgesic effect in exotic felids. In order to minimize adverse effects, it is desirable to work toward treatment with the lowest effective dose when treating chronic pain. Non-steroidal Antiinflammatory Drugs NSAIDs are antiinflammatory drugs which act both centrally and peripherally. The primary effects are believed to be caused by their ability to inhibit cyclooxygenase (COX) enzymes in the arachidonic acid metabolism cascade. The COX-1 isoform is regarded as constitutive (continuously expressed) and is responsible for many homeostatic processes, such as maintenance of gastric mucosal integrity, platelet function, and renal autoregulation. -

They are based explicitly on the available evidence and presented as recommendations to aid clinical decision making for practitioners alongside a detailed review of the evidence. A consensus meeting, involving experts in the treatment of these disorders, reviewed key areas and considered the strength of the evidence and clinical implications. The guidelines were drawn up after feedback from participants. The guidelines primarily cover the pharmacological management of withdrawal, short- and long-term substitution, maintenance of abstinence and prevention of complications, where appropriate, for substance abuse or harmful use or addiction as well management in pregnancy, comorbidity with psychiatric disorders and in younger and older people.

Psychoactive Substance Use Disorders
Psychoactive Substance Use Disorders 14 th March, 2011 Introduction: • In most societies, use of substances to alter mood, behaviours, perceptions etc is accepted. • In our culture, use of alcohol, caffeine and nicotine is widely accepted as normal. • Nevertheless, these substances can lead to all sorts of problems for the user. What are psychoactive substances? • Psychoactive substances (chemicals which affect the central nervous system) become a problem when their consumption becomes habitual, when a craving develops, leading to and/or exacerbating persistent social, occupational, psychological and physical problems. Complexity of substance use disorders: • Substance use disorders know no social class boundaries: people at all levels of society may fall victim. • Understanding and dealing with substance use is very difficult and complex because – Recreational drug use is widespread – Complex interactions of physical, chemical, psychological, socio-cultural variables are involved in drug use – Certain drugs (alcohol, tobacco), although culturally accepted, pose serious dangers to users Dependence and Abuse: • Dependence: cognitive, behavioural and physiological symptoms that indicate the person has impaired control over the psychoactive substance and continues to use the substance despite adverse consequences. • Symptoms: physiological tolerance to the drug and withdrawal reactions when the drug is not available. • Key component: impaired control Distinction: • Physical dependence: when certain drugs are ingested for an extended period of time, the body habituates to the particular substance (tolerance). Thus, larger amounts are needed to achieve the same effects. If the amount of the drug is reduced the body (now habituated to the higher dosage) reacts with withdrawal: cramps, panic, restlessness, sweating, vomiting. Distinction: • Psychological dependence: other types of drugs, although frequently taken, do not alter the body’s tolerance for the drug. -
