Randomized Controlled Trial Multicenter Study Clinical Trial
Spontaneous or neostigmine-induced recovery after maintenance of neuromuscular block with Org 9487 (rapacuronium) or rocuronium following an initial dose of Org 9487.
We have examined spontaneous and neostigmine-induced recovery after an initial dose of Org 9487 1.5 mg kg-1 followed by three repeat doses of Org 9487, a 30-min infusion of Org 9487 or two incremental doses of rocuronium. Mean clinical duration after incremental doses of Org 9487 0.5 mg kg-1 increased from 12.3 (SD 3.4) min to 14.0 (4.0) and 15.9 (5.9) min (P < 0.01), and after rocuronium from 14.4 (5.2) min to 19.2 (5.9) min (P < 0.01). ⋯ These times were significantly reduced to 9.9 (4.5), 8.6 (6.1) and 5.7 (2.5) min, respectively, after neostigmine administration at a T1 of 25% (P < 0.05). We conclude that administration of Org 9487 by repeat bolus doses or infusion was associated with slow spontaneous recovery but neostigmine administration resulted in adequate recovery in less than 10 min.

Randomized Controlled Trial Clinical Trial
Effect of riluzole on acute pain and hyperalgesia in humans.
Riluzole modulates several transmitter systems which may be involved in nociception. Antinociceptive effects have been shown in animal studies, but there are no human data. ⋯ We used a randomized, double-blind, placebo-controlled design, and subjects received riluzole 100 mg or placebo for 2 days with a 14-day interval. The burns produced significant hyperalgesia, but riluzole had no acute analgesic effects in normal or hyperalgesic skin.
