BACKGROUND Opioid abuse has continued to increase at an alarming rate since the 1990 s. As documented by different medical specialties, medical boards, advocacy groups, and the Drug Enforcement Administration, available evidence suggests a wide variance in chronic opioid therapy of 90 days or longer in chronic non-cancer pain. Part 1 describes evidence(More)
Ziconotide is a conopeptide intrathecal (IT) analgesic which is approved by the US Food and Drug Administration (FDA) for the management of severe chronic pain. It is a synthetic equivalent of a naturally occurring conopeptide found in the venom of the fish-eating marine cone snail and provides analgesia via binding to N-type voltage-sensitive calcium(More)
Microglial cells appear to play a vital role in the initiation of certain neuropathic pain states. In order to initiate neuropathic pain, microglia need to be activated. Microglia activation in the spinal cord involves both hypertrophy as well as hyperplasia, progressing through a hypertrophic morphology, with thickened and retracted processes (observed(More)
Chronic noncancer pain is highly prevalent with associated negative effects on function and quality of life of the individuals involved. Opioids have been shown to decrease pain and improve function in some patients with chronic noncancer pain, but they are not always effective and are associated with multiple complications, including drug misuse, abuse and(More)
RESULTS Part 2 of the guidelines on responsible opioid prescribing provides the following recommendations for initiating and maintaining chronic opioid therapy of 90 days or longer. 1. A) Comprehensive assessment and documentation is recommended before initiating opioid therapy, including documentation of comprehensive history, general medical condition,(More)
Both chronic pain and prescription opioid abuse are prevalent and continue to exact a heavy toll on patients, physicians, and society. Individuals with chronic pain and co-occurring substance use disorders and/or mental health disorders, are at a higher risk for misuse of prescribed opioids. Opioid abuse and misuse occurs for a variety of reasons, including(More)
Opioids are broad spectrum analgesics that may be beneficial to alleviate the intense perception of algesia in patients suffering with pain. They have been one of the most controversial analgesics, in part because of their potential for addiction. Opioids or any currently available analgesic will not provide effective analgesia for every patient with(More)
Botulinum toxin (BoNT) is a potent neurotoxin that is produced by the gram-positive, spore-forming, anaerobic bacterium, Clostridum botulinum. There are 7 known immunologically distinct serotypes of BoNT: types A, B, C1, D, E, F, and G. Clostridum neurotoxins are produced as a single inactive polypeptide chain of 150kDa, which is cleaved by tissue(More)
Opioid receptors are widely expressed in the central and peripheral nervous system and in the non-neuronal tissues. Data from animal and human clinical studies support the involvement of peripheral opioid receptors in analgesia, especially in the presence of inflammation. Inflammation has been shown to increase the synthesis of opioid receptors in the(More)
