Complexities Of Chronic Opioid Exposure, Maciej Gonek Jan 2018

Complexities Of Chronic Opioid Exposure, Maciej Gonek

Theses and Dissertations

Studies on repeated exposure to opioids have been carried out for decades yet the mechanisms for certain phenomena such as tolerance are still not fully understood. Furthermore, different medications, such as frequently prescribed benzodiazepines, or different disease states, such as HIV, have their own effects and interactions with chronic opioid exposure that are not fully understood. The overall objective of this dissertation was to investigate the complexities of chronic opioid exposure and how different disease states and medications may modulate the effects of chronic opioids. Our findings demonstrate that the administration of diazepam, at doses that are not antinociceptive or …


Lorcaserin As A Potential Opioid-Sparing Adjunct, Kumiko M. Lippold Jan 2018

Lorcaserin As A Potential Opioid-Sparing Adjunct, Kumiko M. Lippold

Theses and Dissertations

Opioids, such as oxycodone, morphine, and fentanyl, are commonly used medications in the treatment of moderate to severe pain. In spite of their efficacious analgesic properties, their increased prescribing rates by physicians and inherent abuse-related effects have led to the ongoing opioid epidemic. Their clinical utility is limited by the risk of adverse dose-dependent side effects, such as constipation and respiratory depression, and the development of tolerance and dependence. Opioid-sparing adjunctive therapies are sought to address these issues by reducing the dose of opioid needed to achieve analgesia through alternative non-opioidergic mechanisms and as a result, reduce the incidence of …
