Randomized Controlled TrialClinical outcomes during opioid titration following initiation with or conversion to Remoxy®, an extended-release formulation of oxycodone.
Intra- and interpatient variability in opioid response usually necessitates opioid therapy titration to optimally balance analgesia and side effects, whether initiating therapy or converting from another opioid. Remoxy® (King Pharmaceuticals, Inc., Bristol, TN, which was acquired by Pfizer Inc in March 2011) is an extended-release formulation of oxycodone designed to maintain its rate-controlling mechanism following physical and chemical manipulation. A recent phase 3 trial, which required dose titration following initiation or conversion to Remoxy, demonstrated the long-term safety and efficacy of Remoxy in relieving moderate to severe chronic pain. ⋯ Of opioid-naïve patients, 300 (76%) reached a stable dose of Remoxy (mean, 2.2 titration steps), 253 (84%) of whom successfully initiated on Remoxy. Pain intensity decreased from baseline to study completion by approximately 35% for both opioid-experienced and opioid-naïve patients and adverse events were similar to those typically reported for opioids, with a higher incidence rate reported during titration (pre-stable dose period). These data provide important clinical information when initiating opioid-naïve patients on or converting opioid-experienced patients to Remoxy.
