Randomized Controlled Trial Clinical Trial
Efficacy and safety of controlled-release versus immediate-release oxycodone: randomized, double-blind evaluation in patients with chronic back pain.
To compare the efficacy and safety of controlled-release oxycodone given every 12 hours with immediate-release oxycodone given four times daily in patients with persistent back pain. ⋯ Controlled-release oxycodone given every 12 hours was comparable with immediate-release oxycodone given four times daily in efficacy and safety, and it provides convenient, twice-daily, around-the-clock treatment for selected patients with persistent back pain that is inadequately controlled by nonopioids or as-needed opioid therapy.

Randomized Controlled Trial Clinical Trial
Intrathecal coadministration of bupivacaine diminishes morphine dose progression during long-term intrathecal infusion in cancer patients.
To determine the difference in intrathecal morphine dose progression between a continuous intrathecal infusion of a morphine/bupivacaine mixture and morphine for pain relief in patients with cancer. ⋯ The diminished intrathecal morphine dose increase in the combination group is considered to be due to a synergistic effect of bupivacaine on the intrathecal morphine-induced antinociception. A dose increment during long-term intrathecal infusion in cancer patients appears to be related to both disease progression and tolerance phenomena.
