Examination of Palonosetron and Hydroxyzine Pre-treatment as a Possible Method to Reduce the Objective Signs of Experimentally-induced Acute Opioid Withdrawal in Humans: a Double-blind, Randomized, Placebo-controlled Crossover Study[NCT00661674] | 10 participants (Actual) | Interventional | 2008-04-30 | Completed | |||

"The OOWS is a 13-item instrument documenting physically observable signs of withdrawal, which are rated as present (1) or absent (0) during the observation period. Maximum score possible = 13, minimum score possible = 0. T=15 minutes post naloxone administration coordinates with T = 180 (min) for the entire study session.~OOWS scores at T=180 is the primary outcome measure of the study compared with baseline OOWS scores at T=-30 (30 minutes prior to study medication administration). Reported time frames are in relation to time past since administration of study medications.~Mean post-Naloxone OOWS scores (+/- SEM) were determined for pretreatment groups" (NCT00661674)

"The SOWS score is composed of 16 subjective symptoms rated on a scale of 0 to 4 (0=not at all, 4=extremely) based on what subjects were experiencing at the time of testing. 15 minutes post naloxone administration coordinates with T = 180 (min) for the entire study session.~The highest score possible (64) would indicate that the individual was experiencing every symptom of opioid withdrawal to the fullest extent possible while the lowest score (0) would indicate that the individual was not experiencing any symptoms of opioid withdrawal.~Mean post-naloxone SOWS scores (+/- SEM) were computed for pretreatment groups: Placebo, palonosetron, and palonosetron with hydroxyzine" (NCT00661674)
