Results obtained at 3-minute intervals were first averaged within each volunteer across the 30-minute-long bolus administration period and then averaged among the volunteers for each drug treatment. Repeated-measures ANOVA over time was used to compare the two treatments for the presented outcomes. VRS = verbal rating score.
