No peer-reviewed publication reporting this trial's results has been linked yet. This can indicate results are unpublished — a known publication-bias signal. We re-check periodically.
Summary
This study will examine the next-day residual effects of a nighttime dose of gabapentin 250 mg, diphenhydramine citrate 76 mg and triazolam 0.5 mg compared to placebo and each other on simulated driving performance in normal volunteer subjects. It will also examine other measures of next-day performance and next-day sleepiness.
