Time frame: Period 1, 2, 3: Baseline, Days 1 and 3 and 5 (postdose every 10 minutes through 24 hours postdose)
Using a Holter monitor, heart rate was recorded every 10 minutes through 24 hours postdose on Days 1, 3, and 5 of each period. Baseline heart rate was the average of 10-minute readings taken over 2 hours prior to dosing on Day 1 of each period. Postdose heart rate was summarized over 1-hour increments using the average of the 10-minute readings within these intervals. The postdose heart rate for a day was the average heart rate for 24 hours. The least squares (LS) mean change from baseline heart rate is reported. LS mean was calculated using a mixed effects model and adjusted for participant, sequence, period, time, treatment, and time by treatment interaction.
