In the proposed study, we will build upon our previous studies validating and characterizing hyperalgesia in MM samples to explore it's underlying mechanism from a pharmacological perspective. Utilizing a double-blind, placebo-controlled designs, the proposed work will evaluate the ability of dextromethorphan , an N-methyl-D-aspartate (NMDA)-antagonists to diminish or reverse the opioid-induced hyperalgesia complicating the pain states suffered by MM patients. Specifically, in a sample of MM patients, dextromethorphan, theorized to interfere with the development of opioid-induced hyperalgesia will be evaluated for its ability to ameliorate or diminish the opioid-induced hyperalgesia in these patients as reflected by changes on pain threshold and tolerance to both cold-pressor and electrical pain, at peak and trough methadone blood levels. The results of this work will not only provide pharmacologic insight into the mechanisms underlying poor pain tolerance in this at-risk population, but also direction for the medical management of pain complicated by opioid-induced hyperalgesia.
NCT01210066
Providing pain management to the patient who abuses prescription opioids presents a clinical challenge, not only due to concerns about "drug-seeking", but because they have increased sensitivity to pain, a phenomenon identified as opioid-induced hyperalgesia (OIH). In an effort to improve pain treatment, the aims of the proposed work are to evaluate the analgesic and hyperalgesic effects of opioids to acute pain in this vulnerable population, and to examine the role of opioid-induced proinflammatory changes in these responses.

RATIONALE: Nutritional supplements may help prevent loss of appetite, weight loss, and fatigue in patients with advanced cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of two nutritional supplements in preventing loss of appetite, weight loss, and fatigue in patients who have stage III or stage IV solid tumors.
