One trial found speed control still worse the morning after
Fifty-nine volunteers took a sleep-aid dose at 11.30pm and drove 100 km in a simulator 6.5 hours later. Lane position, the trial's own main measure, did not move.
What the study found
The next-morning evidence is one trial and one measure
Fifty-nine volunteers took a sleep-aid dose at 11.30pm and were woken 6.5 hours later to drive 100 km in a simulator. Speed control was significantly worse than after placebo. Lane position, the trial's own primary measure, did not, so the effect is real here and narrower than it sounds.
The caveat · Designed by a competitor's maker
The dose, 76 mg of the citrate salt, is an ordinary amount in an unfamiliar unit, matching the 50 mg of hydrochloride a sleep aid delivers. Under the prespecified testing plan, the remaining comparisons were non-significant or ineligible to test. A competing product's maker designed and part-authored it.
