Effects Of Mu Opioid Receptor Agonists On Intracranial Self-Stimulation In The Absence And Presence Of “Pain” In Rats, Ahmad Altarifi

Theses and Dissertations

Pain is a significant health problem. Mu opioid receptor agonists are used clinically as analgesics, but their use is constrained by high abuse liability. Intracranial self-stimulation (ICSS) is a preclinical behavioral procedure that has been used to assess abuse potential of opioids, and drug-induced facilitation of ICSS is interpreted as an abuse-related effect. ICSS can also be used as a behavioral baseline to detect affective dimensions of pain. Specifically, pain-related depression of ICSS can model pain-related depression of behavior and mood, and drug-induced blockade of pain-related ICSS depression can serve as a measure of affective analgesia. This dissertation used mu …

Opium, the dried resin obtained from the unripe seedpods of the poppy flower, has been used for medicinal and euphoric purposes since ancient times. Morphine, the main active ingredient of opium, and other clinically useful opioid analgesics all mediate their effects through activating the mu opioid receptor. Studies involving the mu opioid receptor knockout mice showed that the interaction with the mu opioid receptor is also responsible for many notorious side effects associated with these drugs including dependence and addiction. Therefore, selective antagonists for the mu opioid receptor are needed to study its function in drug abuse and addiction. Previously, …
