Secondary	Change From Baseline in Cognitive Function-Numeric Working Memory Sensitivity Index (SI)	Working memory is a sum of accuracy measures from the numeric and spatial working memory tasks (sensitivity index [SI]). Working Memory SI is based on how fast the participant responds correctly and how many are correct responses. A high score reflects someone able to hold in memory for a prolonged period. A negative change from baseline reflects impairment compared to baseline.; A series of 5 digits were presented on a computer screen, one every 1.15 seconds, for the participant to hold in memory. This was followed by a series of 30 probe digits for each of which the participant had to decide whether it had appeared in the original series of digits and press the corresponding 'Yes' or 'No' response button as quickly as possible. This procedure was repeated 2 times using 2 different series and probes. Least squares means were adjusted for baseline, period, sequence, time, treatment and treatment*time.	Baseline, 2, 4, 8 hours on Day 3

Secondary	Change From Baseline in Cognitive Function-Word Recognition Sensitivity Index (SI)	Word Recognition SI is based on how fast the participant responds correctly and how many are correct responses. SI ranging from zero (chance performance) to one (perfect accuracy). Higher SI indicates better cognitive function. A negative change from baseline reflects impairment compared to baseline.; The original words from Word Presentation plus 15 distractor words were presented one at a time in a randomized order. For each word, the participant was required to indicate whether they recognized it from the original list of words by pressing the corresponding 'Yes' or 'No' button as quickly as possible. Following each response, there was a delay of 1 second before the next word was presented. Participant's response was measured twice.

Baseline, 2, 4, 8 hours on Day 3
Secondary	Change From Baseline in Cognitive Function-Postural Stability	The ability to stand upright without moving was assessed using equipment modeled on the Wright Ataxia-meter. To measure movements, a cord was attached to the participant who was required to stand for one minute, as still as possible, with feet apart and eyes closed. The amount of sway is expressed as the total angular movement calibrated in units of one-third degree of angle of sway.; The amount of sway is expressed as the total angular movement in the antero-posterior plane and calibrated in units of one-third degree of angle of sway. Higher result indicates better postural stability. A negative change from baseline reflects impairment compared to baseline. Least squares means were adjusted for baseline, period, sequence, time, treatment and treatment*time.	Baseline, 2, 4, 8 hours on Day 3
Secondary	Change From Baseline in Cognitive Function-Self-rated Alertness	The participant was required to rate how they felt "at this moment" on sixteen 10 centimeter visual analogue scales. The scale endpoints were anchored using polar word pairs such as 'drowsy-alert', 'clumsy-well coordinated', 'mentally slow-quick witted' and 'incompetent-proficient'. Responses from the 16 scales were scored to yield 3 main factors: Self-rated Alertness, Self-rated Contentment, and Self-rated Calmness. The possible range of scores are 0 to 100 for each factor and are represented in millimeters on the 10 centimeter line with higher numbers indicating greater alertness. Least squares means were adjusted for baseline, period, sequence, time, treatment and treatment*time.	Baseline, 2, 4, 8 hours on Day 3
